Improved Robot Actuator Motors for Medical Applications

Due to the demanding requirements associated with operation in combat environments, unmanned robotic systems are working towards developing lighter weight systems without sacrificing performance. This requires high power-to-weight ratio actuation systems that can be scalable to various robotic devices and configurations. Conventional actuator motors and hydraulic manipulator arms are known to be unfavorably heavy, which can lead to a multitude of concerns for deployment. As such, Techno-Sciences, Inc., in collaboration with Vecna Technologies and the University of Maryland, proposes to develop a technology centered on artificial muscle actuation, which features high force capability at low operational pressures and light weight. Building upon our extensive experience and related patent portfolio, we will perform analyses and design refinements in Phase II of the project to properly scale the system for an application on the Battlefield Extraction-Assist Robot (BEAR), followed by a full prototype actuator demonstration.
