A Bionic pipe-crawling soft robot based on the pneumatic silicone actuator

Soft, Rotating Pneumatic Actuator.

This article describes a soft pneumatic actuator that generates cyclical motion. The actuator consists of several (three, four, or five) chambers (arranged around the circumference of a circle surrounding a central rod) that can be actuated independently using negative pressure (or partial vacuum). Sequential actuation of the four-chamber device using reduced pressure moves the central rod cycl...

Pneumatic Soft Actuator for Human Assist Technology

In the coming advanced age society, an innovative technology to assist the activities of daily living of elderly and disabled people and the heavy work in nursing is desired. To develop such a technology, an actuator safe and friendly for human is required. It should be small, lightweight and has to provide a proper softness. We call such an actuator soft actuator. A pneumatic rubber artificial...

Bionic Robot Control based on Advanced Updating

In view of the balance control problem of self-balance robot, the reinforcement learning mechanism based on the advanced updating is proposed as a self-balance bionic learning algorithm of the robot. This algorithm can choose optimal behavior above the baseline with the certain probability by using baseline in the advanced updating and unifying the probability curiosity mechanism in reinforceme...

Soft Pneumatic Actuator Fascicles for High Force and Reliability

Soft pneumatic actuators (SPAs) are found in mobile robots, assistive wearable devices, and rehabilitative technologies. While soft actuators have been one of the most crucial elements of technology leading the development of the soft robotics field, they fall short of force output and bandwidth requirements for many tasks. In addition, other general problems remain open, including robustness, ...
