70213 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.
Motorized model assembly kit. Length: 184mm, width: 126mm, height: 82mm.
Comes with conveniently pre-attached motor and switch, and includes everything needed for hassle free snap-fit/screw-together assembly.
The twin rear bars not only help the model to regain its feet, they also aid balance when the robot "jumps", and can be adjusted to help the robot turn as it progresses.
A durable underside cover protects the gearbox and underside of the robot.
Operates for up to 2 hours on a single AA battery (sold separately).
