About mjbots

mjbots Robotic Systems is a small US robotics-components company best known for the moteus family of brushless motor controllers and the qdd100 quasi-direct-drive actuator. The moteus controllers — sold in r4, n1 and related variants through the mjbots web store — turn off-the-shelf brushless motors into high-performance servo actuators, using CAN-FD communications, an integrated magnetic encoder and field-oriented control, and the design is developed openly, with hardware and software published as open source. The qdd100 pairs that control approach with a low-ratio planetary actuator aimed at dynamic legged robots, a product line that grew out of the company’s open-source mjbots quad A0 quadruped project.

Around the core controllers, mjbots sells accessories that make multi-actuator robots practical to build: the pi3hat Raspberry Pi interface with multiple CAN-FD buses and an IMU, power distribution boards, CAN-FD USB adapters (fdcanusb / mjcanfd-usb), cables and encoder magnets. The store ships to a long list of countries, reflecting a customer base of research labs, universities and independent robot builders rather than large OEM accounts. For directory partners, mjbots is a specialist source for torque-controlled actuation components for legged and dynamic robots, with unusually open documentation and tooling for a company of its size.

GlobleMatch Trust Signals

A directory that doesn’t sell stars. Trust Signals are built only from verifiable facts — never from anonymous ratings, and never for sale. There is no single hidden score.

Public information coverage	5 of 9 fields on the standard profile could be filled from public sources. This counts how much public information exists about the company — not how good the company is. The nine fields are listed in the methodology. Claiming the profile lets the company complete the remaining fields itself.
Last verified	9 November 2026 — facts on this profile were checked against the sources listed below. Profiles are re-checked on a published 90-day cycle; this date is never quietly refreshed.

Claim this profile to unlock response record, directory tenure and peer endorsements. The full methodology — what each signal measures and how it is calculated — is published in the Trust Signals methodology, including a change log.
