“PUSH MY BUTTONS AND WATCH ME GO!” The 4th generation of WAO programmable robot kits. WAO Cranium is a 2-wheeled robot that you can program to follow an interesting path “WITHOUT” a personal computer. The brain is an 8-bit micro-controller and keyboard with 33 tactile buttons. Stores up to 60 programming steps and 30 FOR-NEXT multiplex loops. 6 vision sensors (two infrared light sensors to detect obstructions and four floor light sensors enables it to detect a contrast of light like an edge of a table). Programming makes you plan ahead, think systematically and logically, develop problem-solving skills, and challenge you to think creatively. Easy to assemble. Intermediate level kit.
