Technologies Inc. is building and testing a highly agile and powerful
mobile robot capable of lifting and carrying an injured human out
of harm’s way using a gyro balance system mounted on two wheeled
(tracked) base. The gyro system and tracked base are intended to
give the robot a high degree of mobility over rough, uneven terrain
and dynamic balancing behavior for high-speed mobility when speed
phase approach is planned with two successive prototypes being built:
Phase I is research and design phase with the initial design laboratory
prototype being built on a 2-wheeled Segway base. Phase II will
be development of the operational prototype and operational testing.
Phase II BEAR prototype will be composed of a mobility base tightly
integrated with a powerful but sensitive upper body with arms. The
Phase II BEAR prototype will be further enhanced by adding a tracked
capability over the road wheels. The track array will be segmented
in two places allowing the robot to tilt forward or backward to
maintain a low profile on the battlefield, bend down on it “knees”
to pick up a casualty, or all the way into a prone position to pick
up and carry a casualty maintaining a low profile (low crawl position).
The segmented design approach will enable the robot to recover from
falling or being knocked over from any position.
body movement of the BEAR is controlled by a system of hydraulic
valves and pressure sensors and amplifier array which enables a
movement CPU to lift loads by compensating for weight and pressure
by sending messages to a system of hydraulic valve controllers.
Completed robot system will be JAUS compliant.
the design features a torso and arms that use a unique hydraulic
system that can lift and carry its cargo or "passengers"
safely and effectively up to 500 pounds, it could be leveraged for
logistic support missions as well as medical missions.
