Introduce your child to concepts of physics, engineering and robotics while enjoying hours of fun with the Build-It-Yourself Robotic Arm. Kids are fascinated by robots, and learning more about them can help to foster a lifelong love of engineering and science. The Robotic Arm is the perfect way for kids to begin to explore the world of robotics. This set includes all of the pieces necessary to build a real working robotic arm with five motors and five joints. Using the remote control, kids can then make their robotic arm grab items, move upwards and downwards and release objects. The robot features base rotation, elbow and wrist motion and a functional gripper with a five-switch wired controlloer. Maximum lift is 100 grams. Requires 4 D batteries (not included).
