so101-sysid
A calibrated simulation of your SO-101. Identifies each servo's control loop (delay, gains, backlash, gravity) and outputs a MuJoCo model that moves like the real arm.

Cheap robots for actual work.
Open tools that take a $200 robot arm from toy demo to useful machine. Every result is published with its trial count, failures and cost.
Projects
Phone to robot
Film your bare hand on a tripod iPhone. The arm learns the task. No teleop rig, no gloves.
Breakfast
A $200 arm makes breakfast every morning. Success means 19 out of 20 runs, measured, not a single good take.
Rules
Real workTasks someone would pay for or do daily, not tricks.
Honest numbersTrials, failures, cost and human help reported for every result.
OpenCode, models and data released so anyone with the arm can repeat it.
