KaiRider, an easy and fun to build DIY line tracer (line follower) robot from Korea.  The robot kit include the body assembly, connecting motors, motherboard assembly, sensor module assembly and wheel assembly.  No programming is required and therefore no PC is needed.  Your child will learn to use screw driver to fix up the parts with bolts & nuts.  All electronics are plugged into position so no soldering is involved.  Upon completion and some fine tuning, the robot will be able to follow a black line (track) over a white background.  We will be conducting camp/workshop during the December school holidays so that your child will be guided step-by-step to build up the robot.
