PIONEERING Powered exo-suits

 

A powered exoskeleton is a mobile machine worn by a person, powered by a system of hardware and software that delivers assisted or amplified movement.

Our company is comprised of individuals obsessed with making these powered exoskeletons a reality. The BeltScrew™ innovation is made out of necessity to achieve our longterm goals.

The importance of Powered Exo-suits

STRENGTH GAIN

Our passion lies in strength-enhancing exoskeletons, which provide users with increased productivity and a captivating, fun experience.

INJURY PREVENTION

Exoskeletons can assist those who perform strenuous and repetitive tasks, resulting in lowered rates of injury.

REHABILITATION

Exoskeletons are used to facilitate recovery from neurological conditions such as a stroke, resulting in fast and effective recoveries for patients.

the importance of actuators

WEIGHT OF ACTUATORS

To accomplish real-world feats, a powered exoskeleton must be sufficiently strong and powerful.  This often necessitates heavy power components such as gearboxes or hydraulic pumps.

CONTROL OF ACTUATORS

To create fluid and dynamic motion, an actuator must be highly controllable, responding precisely and quickly to the desired motion.  Pneumatics, for example, are often too soft and compliant to create useful motion.

COST OF ACTUATORS

Cost of manufacture is a dominant consideration when choosing an actuation strategy.  Expensive components that offer sufficient power density and control are still unlikely to reach the market.

BELTSCREW™ Power solution

The ideal powered mobile mechanism would have a minimum number of components in the path to actuation. A minimal design means minimal parts and weight with maximal control.

Unfortunately, existing motors today are most efficient when run at higher speeds, making this ideal arrangement difficult to achieve without using step-down transmissions to the joints.

Existing systems use liquids, compressed gases, or gears as transmission methods to step down high motor speeds to usable high torque motion.

However, most of these transmission methods have inherent inefficiencies requiring much larger batteries to compensate for wasted heat. This is where the BeltScrew™ Drive excels as a solution.

The BeltScrew™ Drive is a high performance linear transmission element.  When used in conjunction with Bowden cables, power can be delivered to the location of interest while keeping the majority of the bulk and weight at a central and convenient location, such as a backpack.
