Overview
The goal of this project is to control an mbed robot wirelessly using a Sony Dualshock 3 controller. A C# application running in Microsoft Visual Studio along with MotionInJoy software is used to capture the analog values of the left and right joysticks and transmit them to the mbed over a bluetooth serial connection. The analog joysticks allow for variable speed control of the motors. Additionally, the robot uses several peripherals: a speaker for a car horn, ShiftBrite lights that cycle through on, dim, and high beams, and an IR sensor for back-up collision avoidance. Created by Alexander Ferrara and Luke LeFeve.
