## Description

The robotic arm of the future is here! Assemble this cutting-edge, segmented arm from almost 300 plastic pieces and learn how each part comes together in its intricate mechanical design. This innovative system is controlled by a pair of joysticks that pull and release a network of nylon cables threaded throughout, enabling intuitive and precise movements, much like how tendons work to control the muscles in your arm. The result is a mesmerizing motion reminiscent of a cyborg creature’s tentacles in a sci-fi movie! Use the buttons on the top of each joystick to open, close, and rotate the claw 180 degrees. Challenge yourself or your friends to grab, move, and release various objects. Bonus: Switch out the gripper claw with a model of an eel’s head to transform your robotic arm into a slithery bionic eel. A full-color manual guides model building and experimentation and provides engaging scientific information about how this type of robotic arm works while offering up real-world examples.
