The goal of this project is to create a BeagleBoard-powered robot capable of competing in an autonomous sumo competition in the 3.0 kg weight class (an example). This would have minor hardware and electronics elements, but would focus on communication with sensors using the BeagleBoard and the Linux kernel. At minimum, this involves sensors to detect the edge of the ring and the opposing robot.



  • IR rangefinders
  • Sonic rangefinders (need a way to power-cycle these [1])
  • Edge sensors (used to detect the white lines at the edge of the ring)
  • Header for accelerometer module
  • USB camera (eventually; low priority)
  • Contact sensors (buttons, leaf switches?)

Other I/O

  • Microcontroller to do motor control PWM
    • Socket for ATMega 328
    • Use four L298 motor drivers (one for each motor)
  • Input button to start start match
  • LEDs
    • "Ready" LED (blinks when counting down to match start)


  • Power conversion
    • Motors take 7.2 V, 4A at stall
