Robo Dave was an autonomous, game-playing robot designed and built for Stanford’s ME 218B. Optimized for a specific game board and game protocol, Robo Dave incorporated various electro-mechanical functionalities, including:

• Ability to follow a current carrying wire by using peak LC resonance circuits

• Ability to communicate with the LOC (a provided micro-controller) that spits out real time gameplay information through an SPI

• Ability to read the presence and frequency of a magnetic field

• Ability to sense a given IR frequency, and aim a shooter towards the IR emitter

• Ability to shoot a foam ball 6 ft. into a 1 ft. diameter bucket

• Ability to emit IR at a given frequency to a fixed detector

• Ability to receive new foam balls from a reloader

Robo Dave’s mechanical design was based around two distinct subassemblies - a base level which held our drivetrain, the majority of our circuitry and a stepper motor to drive the turret, and a rotating turret which housed our shooting, reloading and IR sensing subsystems.
