Step 5

• Attach two plastic bumpers using four sheet metal
  screws

11
Step 6

• Attach line follower to the bottom of the robot

12
Step 7

• Plug in the Interface Cable

Test the Behavior of the Line Follower

• SYMBOL Detectors B0
• SYMBOL RightDetect BIT0
• SYMBOL LeftDetect BIT1
• Line_Finder_Check
• Detectors 0
• RightDetect PINC.0
• LeftDetect PINC.1
• DEBUG
• GOTO Line_Finder_Check

Step 8

• Write the line follower program
• Drive the robot forward
• Check both sides of the line follower
• Steer which ever way detects the black line
• Repeat until both sides of line detector see black
