# Overview HumanGenerator generates parametric, rigged, outfitted humans in NVIDIA Omniverse. This project relies on the Makehuman project from https://github.com/makehumancommunity/makehuman. # Getting Started The easiest way to get started is using Omniverse Create. Navigate to the Extensions window and click on "Community". Search for `HumanGenerator` and you should see our extension show up. The extension may take a few minutes to install as it will download makehuman and install it in the Omniverse's local Python instance. For use, check out the walkthrough video on Github. ## License *Our license restrictions are due to the AGPL of MakeHuman. In line with the statements from MakeHuman, the targets and resulting characters are CC0, meaning you can use whatever you create for free, without restrictions. It is only the codebase that is AGPL.

![preview](https://user-images.githubusercontent.com/11399119/226725400-fa9054e3-a13f-4a9f-8294-d08cbee51519.PNG) This repository is for the omniverse extension for crowd simulation. If you are looking for a project that can be run without omniverse, checkout [Python-only crowd simulation](https://github.com/cadop/warpcrowd) A crowd simulator API with a default demo scene. The main python API can be used in a few ways. There is an examples folder showing a few use-cases. Users can also switch between social forces and PAM as the crowds algorithm. The extension will load an populate some demo configuration. It will create an Xform called CrowdGoals. To add a goal for the crowd. Create an xform under the "CrowdGoals". We automatically check for those prims as the method of determing crowd goals. For every additional xform under CrowdGoals, we evenly split the crowd to assign those goals. There are two options for the crowd objects. The default uses geompoints, which is faster and runs its own integration of the forces for position and velocity. It does not interact with any physics in the scene. Alternatively the "Rigid Body" can be used, which creates physical spheres that interact with the scene. Press Play to see the crowd. The default number of demo agents is a 3x3 grid (9 agents). The current simulator in python may struggle above 25 agents, depending on CPU configuration. We plan to support more methods in the future, as well as more crowd simulators. Contributions are welcome.

# kit-cv-video-example Example Omniverse Kit extension that demonstrates how to stream video (webcam, RTSP, mp4, mov, ) to a dynamic texture using [OpenCV VideoCapture](https://docs.opencv.org/3.4/dd/d43/tutorial_py_video_display.html) and [omni.ui.DynamicTextureProvider](https://docs.omniverse.nvidia.com/kit/docs/omni.ui/latest/omni.ui/omni.ui.ByteImageProvider.html#byteimageprovider). ![demo](./images/demo.gif) For a basic example of how to use `omni.ui.DynamicTextureProvider`, please see <https://github.com/jshrake-nvidia/kit-dynamic-texture-example>. **WARNING**: This is a prototype and is not necessarily ready for production use. The performance of this example may not meet your performance requirements and is not optimized. This example is a temporary solution until a more mature and optimized streaming solution becomes available in the platform. This example currently only scales to a very limited number of low resolution streams. ## Getting Started - Requires Kit 104.1 >= - Tested in Create 2022.3.1, 2022.3.3 ``` ./link_app.bat --app create ./app/omni.create.bat --/rtx/ecoMode/enabled=false --ext-folder exts --enable omni.cv-video.example ``` Make sure that eco mode is disabled under Render Settings > Raytracing. From the extension UI window, update the URI and click the Create button. A plane prim will be created at (0, 0, 0) with an OmniPBR material containing a dynamic video stream for the albedo texture. The extension should support whatever the OpenCV VideoCapture API supports. Here are a few URIs you can use to test: - Your own web camera: `0` - HLS: `https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8` - RTSP: `rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4`

# Dynamic Texture Provider Example Demonstrates how to programmatically generate a textured quad using the [omni.ui.DynamicTextureProvider](https://docs.omniverse.nvidia.com/kit/docs/omni.ui/latest/omni.ui/omni.ui.ByteImageProvider.html) API. Tested against Create 2022.3.1. ```console .\link_app.bat --path C:\Users\jshrake\AppData\Local\ov\pkg\prod-create-2022.3.1 .\app\omni.create.bat --ext-folder exts --enable omni.dynamic_texture_example ``` ![demo](./demo.gif) ## *Omniverse Kit* Extensions Project Template This project is a template for developing extensions for *Omniverse Kit*. # Getting Started ## Install Omniverse and some Apps 1. Install *Omniverse Launcher*: [download](https://www.nvidia.com/en-us/omniverse/download) 2. Install and launch one of *Omniverse* apps in the Launcher. For instance: *Code*. ## Add a new extension to your *Omniverse App* 1. Fork and clone this repo, for example in `C:\projects\kit-extension-template` 2. In the *Omniverse App* open extension manager: *Window* &rarr; *Extensions*. 3. In the *Extension Manager Window* open a settings page, with a small gear button in the top left bar. 4. In the settings page there is a list of *Extension Search Paths*. Add cloned repo `exts` subfolder there as another search path: `C:\projects\kit-extension-template\exts` ![Extension Manager Window](/images/add-ext-search-path.png) 5. Now you can find `omni.hello.world` extension in the top left search bar. Select and enable it. 6. "My Window" window will pop up. *Extension Manager* watches for any file changes. You can try changing some code in this extension and see them applied immediately with a hotreload. ### Few tips * Now that `exts` folder was added to the search you can add new extensions to this folder and they will be automatically found by the *App*. * Look at the *Console* window for warnings and errors. It also has a small button to open current log file. * All the same commands work on linux. Replace `.bat` with `.sh` and `\` with `/`. * Extension name is a folder name in `exts` folder, in this example: `omni.hello.world`. * Most important thing extension has is a config file: `extension.toml`, take a peek. ## Next Steps: Alternative way to add a new extension To get a better understanding and learn a few other things, we recommend following next steps: 1. Remove search path added in the previous section. 1. Open this cloned repo using Visual Studio Code: `code C:\projects\kit-extension-template`. It will suggest installing a few extensions to improve python experience. 2. In the terminal (CTRL + \`) run `link_app.bat` (more in [Linking with an *Omniverse* app](#linking-with-an-omniverse-app) section). 3. Run this app with `exts` folder added as an extensions search path and new extension enabled: ```bash > app\omni.code.bat --ext-folder exts --enable omni.hello.world ``` - `--ext-folder [path]` - adds new folder to the search path - `--enable [extension]` - enables an extension on startup. Use `-h` for help: ```bash > app\omni.code.bat -h ``` 4. After the *App* started you should see: * new "My Window" window popup. * extension search paths in *Extensions* window as in the previous section. * extension enabled in the list of extensions. 5. If you look inside `omni.code.bat` or any other *Omniverse App*, they all run *Omniverse Kit* (`kit.exe`). *Omniverse Kit* is the Omniverse Application runtime that powers *Apps* build out of extensions. Think of it as `python.exe`. It is a small runtime, that enables all the basics, like settings, python, logging and searches for extensions. **Everything else is an extension.** You can run only this new extension without running any big *App* like *Code*: ```bash > app\kit\kit.exe --ext-folder exts --enable omni.hello.world ``` It starts much faster and will only have extensions enabled that are required for this new extension (look at `[dependencies]` section of `extension.toml`). You can enable more extensions: try adding `--enable omni.kit.window.extensions` to have extensions window enabled (yes, extension window is an extension too!): ```bash > app\kit\kit.exe --ext-folder exts --enable omni.hello.world --enable omni.kit.window.extensions ``` You should see a menu in the top left. From here you can enable more extensions from the UI. ### Few tips * In the *Extensions* window, press *Bread* button near the search bar and select *Show Extension Graph*. It will show how the current *App* comes to be: all extensions and dependencies. * Extensions system documentation: http://omniverse-docs.s3-website-us-east-1.amazonaws.com/kit-sdk/104.0/docs/guide/extensions.html # Running Tests To run tests we run a new process where only the tested extension (and it's dependencies) is enabled. Like in example above + testing system (`omni.kit.test` extension). There are 2 ways to run extension tests: 1. Run: `app\kit\test_ext.bat omni.hello.world --ext-folder exts` That will run a test process with all tests and exit. For development mode pass `--dev`: that will open test selection window. As everywhere, hotreload also works in this mode, give it a try by changing some code! 2. Alternatively, in *Extension Manager* (*Window &rarr; Extensions*) find your extension, click on *TESTS* tab, click *Run Test* For more information about testing refer to: [testing doc](http://omniverse-docs.s3-website-us-east-1.amazonaws.com/kit-sdk/104.0/docs/guide/ext_testing.html). # Linking with an *Omniverse* app For a better developer experience, it is recommended to create a folder link named `app` to the *Omniverse Kit* app installed from *Omniverse Launcher*. A convenience script to use is included. Run: ```bash > link_app.bat ``` If successful you should see `app` folder link in the root of this repo. If multiple Omniverse apps is installed script will select recommended one. Or you can explicitly pass an app: ```bash > link_app.bat --app create ``` You can also just pass a path to create link to: ```bash > link_app.bat --path "C:/Users/bob/AppData/Local/ov/pkg/create-2021.3.4" ``` # Adding a new extension Adding a new extension is as simple as copying and renaming existing one: 1. copy `exts/omni.hello.world` to `exts/[new extension name]` 2. rename python module (namespace) in `exts/[new extension name]/omni/hello/world` to `exts/[new extension name]/[new python module]` 3. update `exts/[new extension name]/config/extension.toml`, most importantly specify new python module to load: ```toml [[python.module]] name = "[new python module]" ``` No restart is needed, you should be able to find and enable `[new extension name]` in extension manager. # Sharing extensions To make extension available to other users use [Github Releases](https://docs.github.com/en/repositories/releasing-projects-on-github/managing-releases-in-a-repository). 1. Make sure the repo has [omniverse-kit-extension](https://github.com/topics/omniverse-kit-extension) topic set for auto discovery. 2. For each new release increment extension version (in `extension.toml`) and update the changelog (in `docs/CHANGELOG.md`). [Semantic versionning](https://semver.org/) must be used to express severity of API changes. # Contributing The source code for this repository is provided as-is and we are not accepting outside contributions.

# Introduction Here are the ROS simulation packages for Unitree robots, You can load robots and joint controllers in Gazebo, so you can perform low-level control (control the torque, position and angular velocity) of the robot joints. Please be aware that the Gazebo simulation cannot do high-level control, namely walking. Aside from these simulation functions, you can also control your real robots in ROS with the [unitree_ros_to_real](https://github.com/unitreerobotics/unitree_ros_to_real) packages. For real robots, you can do high-level and low-level control using our ROS packages. ## Packages: Robot description: `go1_description`, `a1_description`, `aliengo_description`, `laikago_description` Robot and joints controller: `unitree_controller` Simulation related: `unitree_gazebo`, `unitree_legged_control` # Dependencies * [ROS](https://www.ros.org/) Melodic or ROS Kinetic (has not been tested) * [Gazebo8](http://gazebosim.org/) * [unitree_legged_msgs](https://github.com/unitreerobotics/unitree_ros_to_real): `unitree_legged_msgs` is a package under [unitree_ros_to_real](https://github.com/unitreerobotics/unitree_ros_to_real). # Build <!-- If you would like to fully compile the `unitree_ros`, please run the following command to install relative packages. --> For ROS Melodic: ``` sudo apt-get install ros-melodic-controller-interface ros-melodic-gazebo-ros-control ros-melodic-joint-state-controller ros-melodic-effort-controllers ros-melodic-joint-trajectory-controller ``` For ROS Kinetic: ``` sudo apt-get install ros-kinetic-controller-manager ros-kinetic-ros-control ros-kinetic-ros-controllers ros-kinetic-joint-state-controller ros-kinetic-effort-controllers ros-kinetic-velocity-controllers ros-kinetic-position-controllers ros-kinetic-robot-controllers ros-kinetic-robot-state-publisher ros-kinetic-gazebo8-ros ros-kinetic-gazebo8-ros-control ros-kinetic-gazebo8-ros-pkgs ros-kinetic-gazebo8-ros-dev ``` And open the file `unitree_gazebo/worlds/stairs.world`. At the end of the file: ``` <include> <uri>model:///home/unitree/catkin_ws/src/unitree_ros/unitree_gazebo/worlds/building_editor_models/stairs</uri> </include> ``` Please change the path of `building_editor_models/stairs` to the real path on your PC. Then you can use catkin_make to build: ``` cd ~/catkin_ws catkin_make ``` If you face a dependency problem, you can just run `catkin_make` again. # Detail of Packages ## unitree_legged_control: It contains the joints controllers for Gazebo simulation, which allows users to control joints with position, velocity and torque. Refer to "[unitree_ros/unitree_controller/src/servo.cpp](https://github.com/unitreerobotics/unitree_ros/blob/master/unitree_controller/src/servo.cpp)" for joint control examples in different modes. ## The description of robots: Namely the description of Go1, A1, Aliengo and Laikago. Each package includes mesh, urdf and xacro files of robot. Take Laikago for example, you can check the model in Rviz by: ``` roslaunch laikago_description laikago_rviz.launch ``` ## unitree_gazebo & unitree_controller: You can launch the Gazebo simulation with the following command: ``` roslaunch unitree_gazebo normal.launch rname:=a1 wname:=stairs ``` Where the `rname` means robot name, which can be `laikago`, `aliengo`, `a1` or `go1`. The `wname` means world name, which can be `earth`, `space` or `stairs`. And the default value of `rname` is `laikago`, while the default value of `wname` is `earth`. In Gazebo, the robot should be lying on the ground with joints not activated. ### Stand controller After launching the gazebo simulation, you can start to control the robot: ``` rosrun unitree_controller unitree_servo ``` And you can add external disturbances, like a push or a kick: ``` rosrun unitree_controller unitree_external_force ``` ### Position and pose publisher Here we demonstrated how to control the position and pose of robot without a controller, which should be useful in SLAM or visual development. Then run the position and pose publisher in another terminal: ``` rosrun unitree_controller unitree_move_kinetic ``` The robot will turn around the origin, which is the movement under the world coordinate frame. And inside of the source file [move_publisher.cpp](https://github.com/unitreerobotics/unitree_ros/blob/master/unitree_controller/src/move_publisher.cpp), we also provide the method to move using the robot coordinate frame. You can change the value of `def_frame` to `coord::ROBOT` and run the catkin_make again, then the `unitree_move_publisher` will move robot under its own coordinate frame.

# UDPComms This is a simple library to enable communication between different processes (potentially on different machines) over a network using UDP. It's goals a simplicity and easy of understanding and reliability. It works for devices on the `10.0.0.X` subnet although this can easiliy be changed. Currently it works in python 2 and 3 but it should be relatively simple to extend it to other languages such as C (to run on embeded devices) or Julia (to interface with faster solvers). This new verison of the library automatically determines the type of the message and trasmits it along with it, so the subscribers can decode it correctly. While faster to prototype with then systems with explicit type declaration (such as ROS) its easy to shoot yourself in the foot if types are mismatched between publisher and subscriber. ### To Send Messages ``` >>> from UDPComms import Publisher >>> a = Publisher(5500) >>> a.send({"name":"Bob", "age": 20, "height": 180.5, "mass": 70.1}) ``` ### To Receive Messages #### recv Method Note: before using the `Subsciber.recv()` method read about the `Subsciber.get()` and understand the difference between them. The `Subsciber.recv()` method will pull a message from the socket buffer and it won't necessary be the most recent message. If you are calling it too slowly and there is a lot of messages you will be getting old messages. The `Subsciber.recv()` can also block for up to `timeout` seconds messing up timing. ``` >>> from UDPComms import Subscriber >>> a = Subscriber(5500) >>> message = a.recv() >>> message['age'] 20 >>> message['height'] 180.5 >>> message['name'] "Bob" >>> message {"name":"Bob", "age": 20, "height": 180.5, "mass": 70.1} ``` #### get Method The preferred way of accessing messages is the `Subsciber.get()` method (as opposed to the `recv()` method). It is guaranteed to be nonblocking so it can be used in places without messing with timing. It checks for any new messages and returns the newest one. If the newest message is older then `timeout` seconds it raises the `UDPComms.timeout` exception. **This is an important safety feature!** Make sure to catch the timeout using `try: ... except UDPComms.timeout: ...` and put the robot in a safe configuration (e.g. turn off motors, when the joystick stop sending messages) Note that if you call `.get` immediately after creating a subscriber it is possible its hasn't received any messages yet and it will timeout. In general it is better to have a short timeout and gracefully catch timeouts then to have long timeouts ``` >>> from UDPComms import Subscriber, timout >>> a = Subscriber(5500) >>> while 1: >>> try: >>> message = a.get() >>> print("got", message) >>> except timeout: >>> print("safing robot") ``` #### get_list Method Although UDPComms isn't ideal for commands that need to be processed in order (as the underlying UDP protocol has no guarantees of deliverry) it can be used as such in a pinch. The `Subsciber.get_list()` method will return all the messages we haven't seen yet in a list ``` >>> from UDPComms import Subscriber, timout >>> a = Subscriber(5500) >>> messages = a.get_list() >>> for message in messages: >>> print("got", message) ``` ### Publisher Arguments - `port` The port the messages will be sent on. If you are part of Stanford Student Robotics make sure there isn't any port conflicts by checking the `UDP Ports` sheet of the [CS Comms System](https://docs.google.com/spreadsheets/d/1pqduUwYa1_sWiObJDrvCCz4Al3pl588ytE4u-Dwa6Pw/edit?usp=sharing) document. If you are not I recommend keep track of your port numbers somewhere. It's possible that in the future UDPComms will have a system of naming (with a string) as opposed to numbering publishers. - `ip` By default UDPComms sends to the `10.0.0.X` subnet, but can be changed to a different ip using this argument. Set to localhost (`127.0.0.1`) for development on the same computer. ### Subscriber Arguments - `port` The port the subscriber will be listen on. - `timeout` If the `recv()` method don't get a message in `timeout` seconds it throws a `UDPComms.timeout` exception ### Rover The library also comes with the `rover` command that can be used to interact with the messages manually. | Command | Descripion | |---------|------------| | `rover peek port` | print messages sent on port `port` | | `rover poke port rate` | send messages to `port` once every `rate` milliseconds. Type message in json format and press return | There are more commands used for starting and stoping services described in [this repo](https://github.com/stanfordroboticsclub/RPI-Setup/blob/master/README.md) ### To Install ``` $git clone https://github.com/stanfordroboticsclub/UDPComms.git $sudo bash UDPComms/install.sh ``` ### To Update ``` $cd UDPComms $git pull $sudo bash install.sh ``` ### Developing without hardware Because this library expects you to be connected to the robot (`10.0.0.X`) network you won't be able to send messages between two programs on your computer without any other hardware connected. You can get around this by forcing your (unused) ethernet interface to get an ip on the rover network without anything being connected to it. On my computer you can do this using this command: `sudo ifconfig en1 10.0.0.52 netmask 255.255.255.0` Note that the exact command depends which interface on your computer is unused and what ip you want. So only use this if you know what you are doing. If you have internet access a slightly cleaner way to do it is to setup [RemoteVPN](https://github.com/stanfordroboticsclub/RemoteVPN) on your development computer and simply connect to a development network (given if you are the only computer there) ### Known issues: - Macs have issues sending large messages. They are fine receiving them. I think it is related to [this issue](https://github.com/BanTheRewind/Cinder-Asio/issues/9). I wonder does it work on Linux by chance (as the packets happen to be in order) but so far we didn't have issues. - Messages over the size of one MTU (typically 1500 bytes) will be split up into multiple frames which reduces their chance of getting to their destination on wireless networks.

Run ``sudo hciconfig hci0 up`` to turn the radio on. Then restart the pi. #. Check the status of the robot service * Run ``sudo systemctl status robot`` * The output varies depending on the order of you running various programs, but just check that it doesn't have any red text saying that it failed. * If it did fail, usually this fixes it: ``sudo systemctl restart robot`` 7. Done! ######### Continue to Calibration.

# PupperCommand ## Installation ```shell git clone https://github.com/stanfordroboticsclub/PupperCommand.git cd PupperCommand sudo bash install.sh ``` Then clone https://github.com/stanfordroboticsclub/PS4Joystick/ and follow the installation instructions in the README. ## Starting the joystick publisher 1. The ```install.sh``` script makes the Raspberry Pi automatically look to pair and connect to PS4 joysticks on boot. 2. So once the Raspberry Pi turns on, put the PS4 controller into pairing mode by holding the share and PS button at the same time. The light should start blinking in bursts of two. 3. By around 10 seconds, the joystick should have paired with the Raspberry Pi and the front light on the joystick will change to whatever color you specify in the ```joystick.py``` script. ## Debugging To see if the controller is publishing to the Rover topic use: ```shell rover peek 8830 ``` You can also check the status of the system daemon (systemd) running the ```joystick.py``` script by doing ```shell sudo systemctl status joystick ``` If it shows that the service failed, you can try ```shell sudo systemctl stop joystick sudo systemctl start joystick ``` ## Notes If a packet is lost over the joystick connection, the PS4Joystick code will raise an exception and cause the program to exit. Systemd will then restart the ```joystick.py``` script, which means you will have to re-pair the joystick (hold share + ps4 button until double blinking).
