Tanaka Lab
Machine-translated · View original
A lab that supports people's lives with machines that are safe, comfortable, and long-lasting.
AboutAbout the lab
Machines that are safe, comfortable, convenient, and long-lasting.
The Tanaka Lab aims to devise and build the mechanisms of machines that are useful to people.
If the machines it designs make life safer, more comfortable and convenient, and also last a long time, people's quality of life (QOL) improves.
To this end, the lab works on machine diagnosis and analysis technologies and on developing life-support devices that support daily living.
Its themes are wide-ranging, including walking assist devices, standing-up assist devices, and laser-based gear fault diagnosis.
Key terms
- Life-support device
- A device that supports daily movements such as walking and standing up
- Hemiplegia
- A condition in which paralysis affects either the left or right side of the body, caused by stroke or other conditions
- Neural network
- A computational mechanism modeled on the connections between neurons in the brain. It learns features from many examples

ResearchResearch themes
The design of mechanical systems can be guided by the Three Laws of Robotics, which emerged more than 60 years ago, if they are rephrased as "safe, comfortable and convenient, and long-lasting." Aiming for the machines it designs to improve people's quality of life (QOL), the Tanaka Lab develops machine diagnosis and analysis technologies and life-support devices.
*Illustrative imageWalking assistance
The lab develops a variety of walking assist devices and proposes equipment and programs suited to each user, from patients to older adults to healthy people. People with hemiplegia need a device that can improve their gait, while older adults need support for going up and down stairs safely.
*Illustrative imageStanding-up assistance
For older adults, the lab recommends leaning the trunk forward as a way of standing up that puts less strain on the joints, and studies assistance that helps users acquire this movement naturally. It is developing devices such as one that transforms from a wheelchair into a bed, and one that can be used as a walker after the user stands up.
*Illustrative imageGear fault diagnosis
Gears remain an essential machine element, but inspecting every unit is not easy. The lab studies diagnostic technology that uses relatively inexpensive laser sensors to enable fast, low-cost inspection of all units and continuous monitoring, and in recent years it has also worked on diagnosis using neural networks.
