I present to you my latest project. Utilizing an Arduino, Ethernet Shield, Jaguar Speed Controllers, and an off the shelf wireless router, I developed a custom control system for Team 221 Robotic Systems. Source code and wiring diagrams coming soon!
The driver side of the control system also used an Arduino, Ethernet Shield, a PS2 controller, and a WiFi Bridge. I have an Android app in the works that eliminates the need for the driver station and simply uses the WiFi and accelerometers built into a phone.
The driver station and robot controller communicate using UDP packets and are surprisingly low latency.
