The lab researches robots inspired by the structure and motion control of living organisms.

AboutAbout the lab
Building moving robots inspired by living organisms.
The Min-Sato Lab researches and develops robots inspired by the structure and motion-control capabilities of living organisms.
Its work includes quadruped robots that incorporate animal musculoskeletal systems and underwater robots that move using soft materials.
The lab also researches and develops advanced robot and mechatronic systems to meet the needs of society and industry.
Students who wish to join the lab are required to visit it beforehand and meet with the faculty members.
Key terms
- Soft actuator
- A drive component made of soft materials that moves a robot.
- Muscle-tendon complex
- The structure in an animal's leg in which muscle and tendon work as one unit. It stores energy on landing and reuses it in jumping.
- Direct drive
- A method in which a motor drives the moving part directly, without a reducer or similar transmission.

Inspired by the structure and motion-control capabilities of living organisms, the lab researches and develops biomimetic robots, focusing on exploiting dynamic and nonlinear characteristics. In addition to quadruped robots, underwater robots, and flapping-wing robots, it also works on robot hands and gear measurement robots.
*Illustrative imageQuadruped robots modeled on animals
The lab researches and develops quadruped robots modeled on animal musculoskeletal systems. It reproduces the function of the muscle-tendon complex with links containing elastic bodies and combines them with electromagnetic actuators to develop leg mechanisms that are both flexible and self-stabilizing.
*Illustrative imageRobot hands with high-speed sensing
Building on sensing technology that rapidly measures touch, slip, and proximity, the lab studies robot systems that perform intelligent motions at high speed.
*Illustrative imageBiomimetic soft underwater robots
Using soft actuators such as piezoelectric fiber composites and dielectric elastomers, the lab researches and develops underwater robots with soft, organism-like structures, smooth motion, and fast, efficient propulsion.
*Illustrative imageCompact gear measurement robots
Using a direct-drive (DD) drive system supported by air bearings, the lab researches and develops inexpensive, compact gear measurement robots that can easily be installed on gear production lines.
