BugBot

BugBot is a compact robot built for learning, prototyping, and classroom use.

  • Omnidirectional drive — the robot can move in any direction without turning first
  • Computer vision — the robot can see and identify objects around it
  • Depth sensing — the robot can sense the surrounding space to build a map and avoid obstacles
  • Motion tracking — know where the robot has been and where it is now
  • Wireless — control the robot from your PC with no cables

All controllable from Python with a few lines of code.

from bugbot import Robot

with Robot(0) as bot:
    bot.led("green")
    bot.forward(50)          # drive forward at 50% speed
    import time; time.sleep(2)
    bot.stop()
