Feetech STS32XX open-source firmware released, SO-ARM positioning error reduced
What happened
Someone has written and open-sourced firmware for the Feetech STS32XX series servos, which the author claims nearly eliminates positioning error in most cases. According to the author's figures, SO-ARM101 positioning error dropped from 35 mm to 10 mm, and SO-ARM102 from 25 mm to 0–2 mm. The firmware is open-sourced on GitHub; the above reductions are the author's claims, and the report does not provide independent verification results. Subsequent testing turned to load scenarios: on SO-ARM101/102, gravity compensation calibrated with an empty gripper reduced deviation from about 70 mm to about 35 mm under a 250 g load. The team is soliciting input on how to automatically adapt to different loads, and the relevant code has been placed in the repository.
