This is the small precision line-sensing robot that travels on top of a tablet’s screen by reacting to different light intensities it detects. The robot’s sophisticated optical recognition system enables it to cruise over a tablet’s screen, paper, or gameboard via precision line-sensing. Detecting the difference between the dark line of a “wall” and the white space of a “corridor”, it navigates its way through mazes and labyrinths, follows your finger’s on-screen drawings, and competes with other tablet bots (not included) within specially designed free downloadable games. While its superior intelligence enables it to operate autonomously, you can create codes that program the bot to perform specific functions. Multicolor LEDs indicate when it is on-track or when it’s become lost. Its rechargeable battery provides up to 80 minutes of operation from a 30-minute charge using the included USB cable. 1” H x 1” Diam. (8 oz.)
