LEGO WeDo 2.0 Zig Zag

LEGO WeDo 2.0 line following robot uses a special mechanism to drive and steer

Move and steer with a single motor

ZigZag is a LEGO WeDo 2.0 robot that can follow lines on the ground, and can be remote controlled. Since the LEGO WeDo 2.0 set includes just one motor, I had to adopt a mechanism that allows the motor to drive both wheels, to make the robot able to drive and steer. Thanks to this two-way mechanism, the motor drives one wheel at a time depending on the direction it turns. This WeDo 2.0 robot proceeds in a zig-zag motion, hence the name. You can use this robot as inspiration to make other WeDo 2.0 robots that can drive and steer using just a motor.
