Variable-rigidity reinforced pneumatic soft driver

Abstract

The invention discloses a variable-rigidity reinforced pneumatic soft driver. A non-strain layer is pasted to the bottom face of a drive cavity inner core, and an initial drive cavity inner core is formed. The periphery of the initial drive cavity inner core is wrapped by thin wires on the top face and the bottom face of the initial drive cavity inner core. A drive cavity outer packaging skin layer is arranged on the outer sides of the thin wires to achieve packaging, and a packaged drive cavity is formed. The bottom plane of the drive cavity is pasted to the top face of a rigidity adjusting cavity wrapping body, and the two ends of the drive cavity are sealed by a front end cover and a rear end cover correspondingly. A drive gas cavity is formed in the sealed drive cavity inner core. A variable-rigidity adjusting gas cavity is formed in the rigidity adjusting cavity wrapping body. Multiple endoskeletons are arranged in the variable-rigidity adjusting gas cavity, and particle spheres are distributed in the variable-rigidity adjusting gas cavity and between the adjacent endoskeletons. A gas source gas inlet guide pipe stretches into the drive gas cavity from the rear end cover, compressed air enters the drive gas source through the gas source guide pipe, a gas source gas outlet guide pipe stretches into the variable-rigidity adjusting gas cavity from the rear end cover, and thevariable-rigidity adjusting gas cavity is vacuumized through the gas source guide pipe.

AI Technical Summary

Benefits of technology

This patented technology uses an improved design for vehicles called compound arms. These arm parts are designed without any reinforcement elements like wires inside them, making their overall weight lighter than traditional designs while still maintaining strength and flexibility. They also allow for more accurate movements due to its unique shape. Overall, this new design improves vehicle performance and efficiency.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the functionality and precision of conventional hydraulically expandable or contractable actuators while maintaining their strength against external forces such as tensiles. These issues include limited displacement capabilities, difficulty controllably achieving multiple levels of movement, insensitive torque, and lack of feedback during operation.
