Patent for Sale:

Flexible Hydraulic Muscle    

This technology provides a powerful flexible muscle for performing various types of useful work, including as a robotic arm via hydraulic fluid or pressurized air in a longitudinal biasing system.


A flexible muscle capable of exerting both great and small degrees of force, depending on the application. This technology also includes a fully articulating hydraulic arm comprising two or more of the disclosed hydraulic muscles.

Primary Application of the Technology

Industrial automation, industrial equipment, robotics manufacturers

The Problem Solved by the Technology

Provides a new level of freedom of movement for robotic arms. Enables humans to work in close quarters with robots without risk of significant injury.

How the Technology Solves the Problem

The flexible nature of the disclosed technology allows increased freedom of movement and provides a new level of safety for those working near such a robotic arm.

Competitive Advantage

Prior art robotic arms have much more limited range of motion and are generally unsafe to come into contact with humans. This technology avoids those issues.
