Frankentosh: Building Robots using Mac OS X
 
   
  • Mindstorms -- Building a robot
    • Next, We'll create a robot which follows a line
    • Simple tank of a robot: two tank treads attached to the sides of the RCX, one motor each
    • On the front, we'll put a light sensor pointing towards the ground
    • We'll assume a few things about the line: a dark line on a light background, that the line doesn't double back, and the line's edge is regular
    • These assumptions allow us to use an intersting strategy: follow one side of the line
      • We're always on the left edge, so turn left if it's too light, and right if it's too dark
      • If we weren't using the edge, we'd have trouble determining which direction the bot should turn to adjust to the line
