I’ve published a video presenting a tutorial on how to create a simple drivable chassis using the Unity gaming engine interfacing to Robot code using the WPILib WebSocket simulation. The tutorial will walk you through creating the basic (really basic!) chassis, adding wheels, motors, TalonSRX motor controllers, and gearboxes. The aim is to show just how easy it is to get started.
Here is a link to the Video: https://youtu.be/Qryc2ck-AgY
Here is a link to the starter code and instructions on GitHub: GitHub - kinahawi/FRC-2021-Starter-Project: Unity project to use when getting started with simulations for FIRST Robotics during the 2021 season.
Here is a link to a completed version of the tutorial in case you have trouble or just want to give it a try: GitHub - kinahawi/Chassis-Demo-Complete: Completed chassis demo example using Unity and WPILib
I hope to produce more content and instruction, but that will be somewhat dependent on how useful folks think it is, so please let me know if you like it or if I’m wasting time or duplicating something that already exists.
