I just added another video.

the original video shows the robot with gear ratio 334.2:1 the new video shows the robot running at a gear ratio of 114.7:1.

this makes it a lot faster but it sometimes slips off the line, i also had to increase the operating speed from 8Mhz up to 16Mhz.

Line Following

  • Actuators / output devices: Tamiya double gearbox
  • CPU: Picaxe 20x2
  • Programming language: Basic
  • Sensors / input devices: 2 homemade IR Digital Sensors
  • Target environment: indoor, Flat
