Fat Brain Toy Bionic Robotic Arm Sale

This segmented arm – built by YOU! – is driven by cables like the tendons in muscles, resulting in a mesmerizing motion reminiscent of an eel.

In fact, once it’s built, you can actually switch out the three-pronged claw for an eel head, and then you can try and catch the included shrimps!

The two joysticks intuitively control the arm by pulling and releasing the multiple nylon cables threaded throughout it, enabling easy and precise movement.

The right button rotates the claw up to 180 degrees while the left button opens and closes the claw to grab objects.

And it’s all controlled entirely by the power of your hands – no motors or electricity required!

Dig into the wonders of engineering with the Bionic Robotic Arm kit.
