Description
Kids will be amazed at how the inductive robot follows the Black Line automatically and have great fun.
The robot toys can read BLACK THICK LINE drawn by any BLACK mark pen, cuz it has an optical sensor inside.
Children can plan routes for the robot toys to follow with their own imagination and creativity.
Batteries are installed in the robot with two insulation slices, just remove the insulation slices, then turn on the switch, the robot toys will work.
