Humanoid Robotics from Japan

Living with people,
powered by SI.

SI = Superintelligence

BorgRoid is the name we coined for the robots of the future: living with people, powered by SI. Founded in Nagano in 2023, we are a Japanese robotics company working toward general-purpose humanoids.

Who We Are

A humanoid robotics company
born in Japan.

01

Founded in Japan, 2023

Founded in Nagano in June 2023, as the SI wave was gathering pace, we are among the early humanoid robotics startups in Japan. Today we are based in Kawasaki, Kanagawa.

02

Aiming for general-purpose humanoids

Not a machine built for a single task, but a general-purpose humanoid robot that can work alongside people in every part of life and work.

03

Starting with the joint

Joint modules define a humanoid's performance. We help you select, quote and procure them — supporting the first step of your robot development.

Anatomy

Motor, gear and control — in one unit.

  1. 01

    Motor

    Frameless torque motor. Also available on its own.

  2. 02

    Reducer

    Planetary (DZ) / G4 (SJB) / strain wave (SJC).

  3. 03

    Control & encoder

    Built-in 19-bit dual magnetic encoder. EtherCAT / CANopen / RS485.

Our Core Business

The drive performance
a robot joint needs.

Three series to choose from by size, torque and control interface.
