project specification

Guardian GT

A large-scale industrial exoskeleton allowing an operator to lift and move heavy objects. A dual-armed system that lifts payloads of up to 1,000 lbs, allowing the operator to move, transport and position heavy items reducing risk of personal injury. The robotic arms act as a natural extension of the operator’s real-world arm movements. Each 7-foot arm boasts 7 degrees of freedom, plus a task set-specific end effector that allows the operator to reach objects four feet in front of the mobile platform.

Overview

A dual-armed system that lifts payloads of up to 1,000 lbs, allowing the operator to move, transport and position heavy items reducing risk of personal injury. The robotic arms act as a natural extension of the operator’s real-world arm movements. Each 7-foot arm boasts 7 degrees of freedom, plus a task set-specific end effector that allows the operator to reach objects  four feet in front of the mobile platform.

The distance between the stereo cameras and the shoulders of the robot are the same ratio as you have in the human body. Same goes for the distance between the shoulder and the elbow and the elbow and the wrist. That kinematic equivalent concept enables a brand new operator with no training at all to be able to get into the machine. The robot uses force feedback, which enables the operator to feel the environment through the machine's hand (which consists of three fingers instead of five). 

A modified COTS-tracked base can travel at 4 mph through the use of a diesel-fueled engine.
