SO-ARM 102 goes open source in the next few weeks.
What's new:
- A parallel gripper: the jaws stay parallel through the whole stroke instead of pivoting around the object as they close.
- PET-CF instead of PLA+ for a much stiffer frame.
- A topology-optimized structure.
- Wider joint rotation and folding range.
- STS3250 servos on the first shoulder joint.
Compared with the SO-ARM 101, that adds up to 2.5x the payload, roughly 2x better positioning accuracy, roughly 1.6x the movement speed, and about 36 mm more reach.
It runs on Hugging Face LeRobot, so the same tooling, training pipeline and tutorials for the SO-ARM 101 work on it from day one. posted an update 4 days ago

In November, with https://huggingface.co/Robonine are starting work on the next version of the SO ARM 102 manipulator. The version will be open source and agreed upon with https://huggingface.co/therobotbuilder the creator of the original manipulator.
We are planning to:
- increase positioning accuracy by approximately 2x using Feetech STS 3250 motors
- increase working payload from 200g to 300g
- increase rigidity using parametric design optimization and stiffer plastic
- increase length to 550 mm
- increase folding angles
- use ISO 9409-1-50-4-M6 mounting standard for the gripper
- use a parallel gripper in the default version
- update the mounting plate for different camera types, M3 grid with 12.5 mm pitch
- add table mounting standard 80x80 M8
The number of degrees of freedom and basic kinematics will remain the same.
Are there other things missing for working with SO ARM 100?
- Any standard inputs/outputs, for example?
- Status indicators?
- Perhaps some types of mounting for third-party grippers are more preferable?
- Anything else?
