A Depressurization Assistance System for a Seated Patient on a Wheelchair

Journal of Robotics and Mechatronics, 2012
For reducing the risk of pressure sores caused by a long period of sitting in a wheelchair, we have developed a depressurization motion assistance system that is low in cost and suitable for practical use. Our developing system consists of a seat cushion that the patient sits on and four air cells that can lift or incline the seat cushion.

Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

Advanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful
