This is a project about control robot with Unity3D.
I am using websocket to develop communication the module. Because webGL does not support normal socket and the only way to use unity on Linux ARM is webGL. This project can also runs on all platforms.
Websocket plugin for unity: https://github.com/y85171642/UnityWebSocket


As for ROS client, I am using this project: https://github.com/Pithikos/python-websocket-server
The delay is acceptable in normal WIFI environment. This project shows that it is convenient to develop GUI for robot with Unity.
