Finally put together Lynxmotion’s Viper kit. The chassis and wheel provide a nice starting point. For our outfit used Adafruit motor shield on a Arduino Uno. We originally started with a Arduino 101 but ran into some library incompatibilities and switched to Uno. Lynxmotion has some line detectors that fit nice in the chassis and to identify opponents a HC-SR04 was added on top. We had been playing with Adafruit’s 2.8″ touchscreens which made a nice addition. The screen we displayed the current direction of the robot, the readings from the sensors, motor RPM and general status. A big start/stop button rounded out the display. Note sure we should leave the screen on for combat, but it’s cool for around the house.
