OpenArm Hardware Modifications for Cloth Folding

Custom 3D-printable parts used in the Unfolding Robotics project, where we trained a bimanual robot to fold t-shirts with a 90% success rate. These files modify the standard OpenArm.

File Description

J4_5cm_extended.step Extended upper arm (bicep) segment, adds +5 cm of reach to compensate for the lack of a hip/torso in our setup. STEP format for easy modification.
