4 years & up. Meet Sammy, the cute little peanut butter and jelly sandwich that is actually a robot! This robot teaches coding principles and skills in a fun and exciting way. Simply lay down a sequence of physical code cards or the map cards and send the robot driving over them. The OID optical scanner on the bottom of the robot reads the code cards one by one and loads the program. The integrated output gear allows children to build simple robotic creations with arms or other moving parts that respond according to the program's instructions. Your child can program the robot to move in different directions, activate its output gear, light up its LED, play sounds, and respond to different function cards. This robot kit features 30 lessons that teach physical engineering and problem solving skills through a series of building and coding lessons.
