Founded in Japan, 2023
Founded in Nagano in June 2023, as the generative-AI wave was gathering pace, we are among the early humanoid robotics startups in Japan. Today we are based in Kawasaki, Kanagawa, working closely with customers across Japan.
Humanoid Robotics from Japan
Living with people,
Living with people,
powered by AI.
That is BorgRoid — the name we coined for the robots of the future.
Founded in Nagano, Japan in 2023, BorgRoid is a Japanese robotics company working toward general-purpose humanoid robots. As a first step, we supply the DZ and SJ series of robot joint modules to customers in Japan.

Who We AreA humanoid robotics company
A humanoid robotics company
born in Japan.
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.
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.
Our Core BusinessThe drive performance
The drive performance
a robot joint needs.
