Servo Cylinders in Parallel Mechanism Space Structures Robot

Six Standard (A1) Servo Cylinders were used on the NINJAR robot to help NASA meet its goals for robotic in-space assembly and manufacturing. The Servo Cylinders are mounted in a parallel kinematic arrangement to provide multiple degrees of freedom and high stiffness to the structure. The parallel manipulator allows for complete control over the structure’s shape with very high precision and repeatability.

Throttle Valve Actuators

Using a triple redundant version of Ultra Motion’s Phase Index absolute position sensing technology, these actuators provide high accuracy, high bandwidth control over propellant flow in a manned spaceflight application. In order to comply with NASA-STD-5017 requirements, these actuators were designed to provide utmost reliability across extreme environmental conditions (shock, vibe, saltwater submergence, and a wide temperature range)
