Actuation technology for the development of robotic systems

Reference TD-IT-1013

TECHNOLOGY DESCRIPTION

An advanced actuation system for robotic arms has been developed to operate in extreme environments such as space, underwater, nuclear facilities, and high-temperature settings. The system employs hydrostatic transmissions (“Fluid Wires”) to transfer motor power from an external Actuation Box to lightweight, passive robotic arms. By removing electronics, sensors, and actuators from the arm itself, the system enables exceptional thermal management, radiation shielding, and mechanical simplicity. It also allows for sensorless yet precise torque control, ideal for applications where reliability and control fidelity are critical. Demonstrated capabilities include underwater operation, resistance to radiation levels up to 1.5 MGy, and initial compatibility with vacuum conditions. Its modular architecture supports scalable and reconfigurable implementations.

• All motors and sensors housed in a central Actuation Box (away from hazardous zones)
▪ Extreme environmental resistance (radiation, vacuum, heat, underwater)
▪ No motors/gears in robotic arm → lightweight, slender, and safe
