Exoskeletons reduce risk of injury and augment user strength

29 January 2020

Sarcos Robotics has developed two technologies to help reduce the risk of injury within industrial and hazardous environments. The Guardian GT is a human-controlled, dual-armed, exoskeleton system that enables the operator to lift and move heavy objects, or to cut pipelines and handle hazardous materials from a safer distance.

The Guardian GT is designed for dexterity and is kinematically equivalent, which means the cameras and arms on the robot are positioned in a way that mimics the human body. Each seven-foot arm is controlled by the user’s real-world movements, making the robot feel like a natural extension to the user’s arms. Force feedback means the operator is also able to feel the environment through the machine’s hands. These features mean that an inexperienced user is able to control the machine with little training.

A second technology designed by Sarcos is the Guardian XO, a full-body, battery-powered exoskeleton. The Guardian XO has been designed to augment operator strength without restricting freedom of movement. The exoskeleton allows the operator to safely lift and manipulate up to 90 kilograms (200 pounds) without fatigue or strain.

The onboard power source offers up to eight hours of operation on a single charge with a hot-swappable battery design extending operational uptime and flexibility. In the event of sudden power loss, redundant hardware and software limit-stops enable "passive braking" to prevent operator injury. The XO Pod docking station facilitates battery charging as well as easy don/doff operation and configurations for transport/shipping. Users are also able to select from different end effectors depending on the use case.
