Established May 26, 1988.
If we must work at a job, why not work at a job that gives you a sense of fulfillment and happiness　and not only makes others feel happy but is beneficial to people in their everyday lives?
Muscle was established from the dream of an engineer.
We named the company “MUSCLE” out of our determination to make robots that move as flexible as a human muscle can be.

We specialize in motion control for various types of motors. By using inexpensive stepping motors, we succeeded in creating a product with high performance at an unprecedentedly lower cost. Our systems have been adopted in various fields such as industrial embroidery sewing machines, medical equipment such as ventilators, semiconductor/HDD manufacturing, and inspection equipment, which have earned us a great reputation in the industry as a unique “control” specialist.

We are a small company. However, we, as an elite force with advanced techniques and great sales capabilities, develop products in-house as a fabless manufacturer by outsourcing manufacturing to top-notch companies.

While owning numerous patents and expertise at hand, we are growing and evolving in order to achieve what other companies cannot do.
In 2010, our “Yume Robo” gained much popularity at the Japan Industry Pavilion at the Shanghai World Expo. Taking the opportunity of this success, we transformed ourselves into a robot manufacturer, which had been a dream of ours ever since the founding of the company.We started developing a much-anticipated nursing-care robot, “ROBOHELPER SASUKE” and launched the sales of this robot in 2016.
In 2018, we developed a robot that livens up dance performances and showcased its performance at the G20’s VIPT reception in 2019, also our care-robot was exhibited at the Osaka section then as well.
While working on further improvements to our existing products, we aim to produce products that are beneficial to the well-being of people's lives.
The next milestone we have in our sight is the Japan Expo in 2025.
