Light Activated Car

• Group Members
• Matt Burich (team leader)
• Mike Lechtenberg
• Nick Treder
• TA Jong Hoon Nam

2
Objective

• Design and program a model car to follow a light
  source that moves at varying speeds in forward
  and backward directions.

3
Tasks

• Modified RC car
• Removed unnecessary components
• Mounted sensors on front and rear
• Adjusted cars alignment
• Mounted handyboard
• Wrote program with Interactive C 4.0
• Use average sensor value equation
• Fine tune program via trial and error to minimize
  OS

4
Systems Explanations

• Mechanical
• Solid axle, single motor driven
• Front actuator left in car to maintain wheel
  alignment
• Hose, Paint and misc parts
• Electrical/Programming
• 2-Photocell sensors,2-touch sensors,Handyboard
• IC Language, Priority-Based Programming, Feedback
  PID Controller

5
Conclusions

• Priority-Based Touch sensors are top priority,
  light sensors are middle priority, and motor is
  lowest priority
• Tracking error reduced by several trial-and-error
  runs
• Fine tuned PID controller gains
• Eliminated 3 sensors
• Added light shields
• Painted car black
