SO101 Robot Arm Fin-Ray Gripper

New gripper for the SO101 Robot Arm. This uses the Fin-Ray effect for controlled buckling to allow gripping strangely shaped, thin, and brittle objects. Overall, it works much better than the standard gripper across a variety of shapes. Unlike most standard fin-ray grippers, we use slanted ribs and an angled bottom to control the direction of buckling; Some FEA simulation output is attached. When assembling, you need an additional 8x M3*20 bolt to attach the blade to the jaws. When calibrating you should press the jaws together as far as they will go so the ridges mesh. This will allow you to pick up thin objects like paper or sheet metal.
