Power components

for

mobile Motion products

 

Rise Robotics invents, develops, and manufactures novel power components that are affordable, lightweight, and efficient.

Our first product, the Cyclone Rope Piston, tensions and contracts two points efficiently using fibrous rope and injection molded plastics.

It is driven by conventional electric motors, and is intended to power wearable robotics used in the Construction, Industrial, and Medical markets.

we like Powered exoskeletons

 

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 the intent of pioneering exoskeletons.

The importance of Powered Exoskeletons

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 expeditious and effective recoveries for patients.

the exoskeleton problem is an actuation problem

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.

Out of our intentions to see exoskeletons quickly reach the market, we developed a blank slate approach to actuation.

By thinking strictly in methods of contact mechanics, we developed the conical differential, a cost effective way of reducing high speed rotary torque to slow linear motion through methods of rolling friction.

This insight into a new family of actuation has just begun. The Cyclone Rope Piston's performance is competitive with existing solutions, offering a low weighthigh speed, high force, and controllable solution.

CYCLONE ROPE PISTON BENEFITS

 

HIGH PERFORMANCE
The elimination of friction as a critical function of energy transfer allows for efficiencies in the 90% range.

 

BACK DRIVABLE
The Cyclone Rope Piston can deliver power as easily as it can regenerate power on the backstroke.

LOW COST
The nature of distributed surface pressure of rope over rolling surfaces allow for the use of molded plastics.

 

LIGHTWEIGHT
Thanks to favorable mechanics, the Cyclone Rope Piston is rendered lightweight in comparison to existing transmissions.

ELIMINATION OF CUT GEARS
The conical differential approach eliminates the need for precision machining of cut gears.

 

VARIABLE PROFILES
Depending on specific linkage designs, Profiles can be generated to counteract force curves with variable profiling.

Cyclone Power solution

The ideal powered exoskeleton 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 fast speeds making this ideal arrangement difficult to achieve without involving step-down transmissions.

Existing systems use compressed gases, fluids or gears as transmission methods to step down high motor speeds to usable high torque small motion. However, most of these transmission methods have inherent inefficiencies requiring much larger batteries to compensate for wasted heat. This is where the Cyclone Rope Piston excels as a solution.

 
 

The Cyclone Rope Piston 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.
