This unique Robotic Arm is hand powered and can pick up and relocate items using four degrees of freedom and an articulated grabber hand. The whole crane can rotate 360 degrees, allowing this miniature robot to perform the complex actions of its real life counterpart. Kids and robotics enthusiasts alike will have fun building this STEM-based kit that pays special attention to important scientific principals including gear reductions and power transfer through the robotic arms intricate gearing techniques.
