Before you build
Learning setups often pair a follower arm with a leader arm you move by hand. Check whether the maker’s cost covers one arm or both.
Hobby servos keep a build affordable. Check the documented actuators, reach and payload before you plan a task around them.
A ready LeRobot, ROS 2 or MuJoCo setup can save weeks. Look for calibration and teleoperation code, not only CAD.
Costs are the maker’s documented figures, with their original scope. Stars are recorded GitHub snapshots, never a quality score. Search the whole collection
