Manufacturer profile
mjbots
Open-hardware developer of quasi-direct-drive servo actuators and the moteus brushless controller family for legged and dynamic robots.
Identity boundary
Profile, not endorsement.
RCI links the manufacturer identity to public evidence. Inclusion does not imply independent verification of performance, commercial availability in every region, or any commercial relationship with RCI.

1 models · 14 claims
2 distinct claim sources and 5 explicit unknown, conflict or limitation entries.
Editorial next step
Deepen the weakest conditions
Prioritize thermal, lifecycle, compatibility and independent-test gaps.
Questions RCI applies before comparison.
These checks define the evidence work still required; they are not claims about this manufacturer.
A
Motion & Actuation
- Separate continuous, peak and stall output
- Preserve duty cycle, thermal and cooling conditions
- Resolve gearing, backlash, encoder and brake boundaries
- Pin voltage, firmware and communication variant

qdd100 beta 3
This record freezes the third beta revision of the mjbots quasi-direct-drive servo. The official page is unusually explicit about torque-versus-time behaviour, publishing a four-step torque-duration ladder down to an indefinite 3.3 N·m point under one stated thermal condition. The page also states the unit is not currently stocked and carries a 50-unit minimum order.
