Tamiya 7021370213 Springing Arm Robot The Educational Construction Series provides a range of informative and educational experiences through the construction of fun models. The Springing Arm Robot is no exception. The effective yet easy-to-understand mechanism allows the Springing Arm Robot to use its two motor-powered flexible arm-like appendages to propel itself rapidly forwards in an energetic springing motion. It can cover 1 meter in a mere 4-5 seconds, and thanks to the bar-shaped rear stays on the back of the robot, it will automatically right itself if it gets put the wrong way up.Specifications:Motorized model assembly kit.
