The new-generation robotic arm in the SO-ARM series, SO-ARM 102, has launched after approval by Rob Knight. Compared with the previous generation SO-101, its payload is increased to 2.5 times, positioning accuracy is about 2 times, movement speed is about 1.6 times, and its reach is about 36 mm longer; the gripper remains parallel throughout, and key joints use Feetech 3250 servos. SO-ARM 102 runs on Hugging Face LeRobot, and its tools and workflow are the same as those of SO-ARM 101, so existing setups can be used directly. The structure is optimized for stiffness with PET-CF material, and it can also be printed in PLA.
