About this product

The Thames & Kosmos Bionic Robotic Arm Kit is a hands-on STEM toy that allows users to assemble a segmented robotic arm from nearly 300 plastic pieces. Operated manually through dual joysticks and nylon cables, the arm mimics biological movement, enabling precise control of the claw's opening, closing, and 180-degree rotation. It includes a detachable gripper claw and a bonus eel head attachment for alternate use. The kit comes with a full-color manual offering step-by-step instructions and scientific insights into mechanical engineering and biomimicry. No batteries or motors are required.
