Elenco Line Tracking Robot Kit

It barely worked, and frustrated my son.

Surprised to see negative reviews of this. My son and I built it when he was five, and it gave him many, many hours of amusement, making tracks on the floor with electrical tape. Eventually, one of the wheels jammed, so it spun in a circle, as one of the other reviews described. I helped him take it apart, and he fixed the wheel and put it back together. I think this is an excellent toy on its own merits as well as being a good teaching tool for electronics and machinery.

It is doing the job but it requires a very smooth surface and the black trail must have a certain width to work. Too wide or too narrow is not good.

Son enjoyed putting it together but it only spins in one place on the black line. It doesn't matter if it's a black marker line on white paper or electrical tape. Cool idea just wish it worked :-(

Simply does not work. Won't follow a black line no matter how wide or narrow we make it.
