Chrome Dome is a fascinating robot! It can follow a black line (use black electrical tape or a black marker) on a light surface. Not only does it reliably follow the unique "line track" that you lay out for it but it also does it with style. Features colorful brilliant blue and yellow LEDs that flash back and forth as each motor is activated. This robot features 4 separate adjustable controls to allow fine tuning of "Chrome Dome's" line tracing abilities. Fascinating to watch, fun to build and operate.
