SO-101 6DoF + Symmetric Gripper

An upgrade kit for the SO-101 robotic arm, adding a 6th degree of freedom (wrist pitch + yaw) and a symmetric parallel-jaw gripper. The 6DoF wrist enables the arm to approach objects from any angle, and the symmetric gripper provides balanced grasping force -- together enabling seamless integration with state-of-the-art grasp generation models and making it easier to grasp objects reliably.
