This construction kit challenges you to build a fully functional VEX® Robotic Arm. With four points of motion, you can use each control knob to pick up surrounding objects with the claw!
The Robotic Arm™ can raise objects up to 14 inches by twisting the "left" hand knob forward and backward. It also extends out to 10 inches by twisting the "right" hand knob forward and backward. By turning the dial on the rear of the Arm will allow you to pick up many common household objects using the claw! The whole crane can rotate 360 degrees, allowing this miniature robot to perform the complex actions of its real-life counterpart.
