THA Bionic Robotic Arm

A segmented bionic arm driven by cables like tendons, producing mesmerizing, tentacle-like motion. Assemble the arm from almost 300 plastic pieces and control it intuitively with two joysticks that pull multiple nylon cables: the right joystick controls the upper body and the left joystick controls the lower body. A touch of the right button rotates the claw up to 180 degrees; the left button opens and closes the claw. Move the joysticks and press the buttons to maneuver the claw to grab, move and release objects. The arm operates without motors or electricity. Bonus: replace the gripper claw with an eel head to transform the arm into a bionic eel and try picking up the included small shrimp models. A full-color manual guides model building and provides scientific information and real-world examples.
