The importance of actuation

 

Rise Robotics designs, manufactures and assembles breakthrough components for more efficient mobile products. The company was founded in 2011 to advance the robotics industry, with the ultimate goal of enabling powerful wearable exoskeletons for all.

Our first product, the Cyclone Cable Piston enables new mobile robotic products in productivity fields such as Construction, Industrial, and Medical markets.

This new power handling mechanism avoids the need for precision hardened metal parts by avoiding the need for friction to function.

The Cyclone Cable Piston was invented out of the necessity for a more portable, efficient, cost effective, and easier to maintain power solution for mobile exoskeletons. Traditional components and methods are inherently limited by the requirement of friction to function making the field of robotics a complicated, slow and expensive market to grow and adopt.

Using best practices in contact mechanics, the Cyclone Cable Piston is a cost effective way of reducing high speed rotary torque to slow linear using only rolling contact. The Cyclone Cable Piston excels at higher reduction ratios unlike conventional gear box methods.

Lightweight and efficient, the Cyclone Cable Piston reduces motor size and usage.

CYCLONE cable 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 Cable Piston can deliver power as easily as it can regenerate power on the backstroke.

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

 

LIGHTWEIGHT
Thanks to favorable mechanics, the Cyclone Cable 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.

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.

Cyclone 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 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 Cable Piston excels as a solution.

 
 

The Cyclone Cable 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.
