Line Follower Robot Chassis 3D Printed

Parts needed:

• 2x yellow TT motor + wheel kit
• 1x Arduino Uno or clone
• 1x Motor shield for Uno
• 3x Line sensor
• 1x small LiPo battery
• wires, standoffs, rubber band, nuts and screws

Notes

• Instead of the three line sensor modules you can also use an 8 channel sensor array. The chassis has holes for this sensor board also. This array has analog output and you need an Arduino Uno clone with additional A6 and A7 pins to use all 8 channels of the sensor
• When you use LiPo packs without protection you should also use a LiPo low voltage alarm
• I use a screw in one of the front holes and let the front part of the robot slide on the screw.
