Before you build
A typical quadruped needs several motors per leg. Check the actuator type and count against the documented cost.
Look for published gait or reinforcement-learning controllers and a simulation model you can test first.
Check whether the boards are custom designs with published files or off-the-shelf parts you can buy.
Costs are the maker’s documented figures, with their original scope. Stars are recorded GitHub snapshots, never a quality score. Search the whole collection
