Build Your Own Robot Arm

Engineers team up to design and construct an 18-inch-long robotic arm that can successfully pick up a paper cup. Each group is given the exact same set of materials, but it is up to them to decide what to use and how to use it. It is a straightforward, yet challenging plan for your physical science class.
