Start Year 02011

Arron Accosta and Blake Sessions, two MIT graduated students who came together over the vision of personal wearable powered exoskeletons. Blake Sessions envisioned tangible means of being superhuman and Arron was inspired to be his first follower. Science Fiction exosuits like Iron Man inspired them both. They intend to become the most influential figures in the wearable hardware space.

Rise Robotics plans to introduce powerful and economical robotics into our reality.


THE HIP BELT

Year 02011

321.png
 

The first piece of innovation at the Rise Robotics lab was a passive mechanical hip belt to give the user the feeling of floating in water while suspended in an exoskeleton. Referred to as the Hip Belt, it consisted of a series of concealed cables and pulleys donned around the waist to unload the hip from stresses.  The configuration allowed for the support of a person's full weight without any imposition or restriction on their motion.


THE BOUNDERS BOOT

August 02012

321.png
 

With the intention of providing an elastic trampoline experience anywhere in the city, Rise developed the Bounders boot.  It consists of a "foot" component coupled to a novel compound fiberglass spring design that provides tremendous elastic energy at a minimum of weight and bulk.

The new spring design mimics the Achilles tendon efficiency by utilizing inexpensive and high-performance pultruded fiberglass sheets cut into diamond shapes to minimize structural and material waste.  Applied to the ankle joint, the user feels increased ankle elasticity that enables enormous stride lengths while keeping the user grounded.


THE ANKLE CLUTCH

The bounders boot demonstrated the exotic spring design well, but the passiveness of the boot was limiting the full potential of improving the user's experience. The Ankle Clutch (as shown above) was an improvement of the Bounders boot by integrating a flexural clutch that releases the spring's stored energy at appropriate moments to allow for both amplification of motion at some times during usage as well as complete freedom of motion at other times, resulting in power amplification at the user's whim.


THE FLIGHT SOURCE SPRING

November 02012

321.png
 

Spring innovations lead Rise Robotics to compacting the fiberglass elements into a dense and modular assembly. As a successful component, Rise Robotics found it as an answer to the robotics industry where power density is a much desired trait. It worked by using tensile rope elements in tandem with the tessellated diamond shaped pieces of fiberglass. Nicknamed the "Flight Source", the spring proved to be incredibly power dense compared to traditional helical steel springs. 


THE HERO BOARD

Year 02012

321.png
 

To demonstrate the potential of the Flight Source springs to customers, a simple spring testing jig was made to compare and feel the differences between old and new paradigms. This physical demonstration proved to be such a successful way of communicating the importance of the proposed Flight Source Springs that commercializing the jig into a portable trampoline could be a way of generating revenue to help sustain spring research and development. This project was nicknamed "the Hero Board".

Although the Hero Board was incredibly power dense and lightweight, it had complaints of not being robust enough for a product with such a high parts count. The Hero Board also suffered the shortcomings of a classical trampoline in the sense that they can only return energy not amplify. The Hero Board product was not worth mass producing until some of these short comings could be answered.

After some developed insights into product development, the team went back to improving the Flight Source Spring component.


THE FIBER BLOCK SPRING

Year 02012

321.png
 

Working with the overtly complex Flight Source Spring components in the Hero Board informed the team to simplify and increase robustness of the components they design. With new insights and experienced pain points from trying to implement components to systems, the Flight Source Springs complexity dropped significantly. This improved version is nicknamed "The Fiber Block".  Although not as ideal as working with pure tension and pure compression, the Fiber Block Springs eliminated the need for tensile string elements to simplify assembly at the cost of power density metrics. The improved spring component also featured the ability to add or remove sections to tune & change the behavior characteristics of the spring. The overall column-like form it takes on is more familiar to what engineers are used to when designing with off the shelf components for hopes of better acceptance & adoption.

The purity of the Flight Source was not forgotten, and alternative methods for manipulating the tensile rope elements were under development. This intension lead to the fact that actuation is a major limiting factor, not the elastic element.

Articulating the Fiber Blocks or the Flight Source springs became the real challenge. There was no actuator that came close to matching the efficiency of the light weight springs designed. This led to the insight that it is not springs that is not holding back industry, it is actuation.

The quest to develop a comparable actuator begins.


PROTOTYPE OF THE FIRST ROPE PISTON

August 02013

321.png
 

Blake Sessions discovered a way of compacting and balancing the ancient Chinese Windlass mechanism as a cost effective way of efficiently converting rotary motion to linear motion. This compacted windlass approach is known as the "conical differential drive".

As a proof of concept, a 31 inch actuator was made utilizing a 1mm steel cable that could pull 45lbs over 100mm in an astounding 1.8 seconds. While weighing 300 grams. However, due to its wide cross-sectional area, its rated Pounds per Square inch rating resides at 3.17, Rise Robotics's current means of measuring its ultimate performance. Its application demonstration was to assist Hesham's lift project an affiliate of Rise Robotics. As with any new innovation, failure modes are not entirely understood. This design would fail imminently if the lines were ever tangled by improper handling.

THE NUVU MINI CYCLONE 1.1 ROPE PISTON

September to October 02013

An invention that behaves unlike any other linear actuator required customer validation wether it belonged in the marketplace as a usable component. Arron and Blake took this invention to a nearby technical high school to educate and distribute miniaturized rope pistons in hopes of seeing applications where the device is put to best use.

12 of these actuators were distributed amongst student projects. 5 of them still function today and are consistently recycled from old projects.

THE CYCLONE 1200 SERIES

December 02013 to June 2014

321.png
 

The first Cyclone Rope Piston to be publicly debuted in front of Make MITFirst Robotics and Maker Fare. It is a robust improvement to the the Cyclone Mini. Featuring a balanced symmetry with one gear stage, this actuator was a substantial improvement of performance due to the utilization of Dyneema and Kevlar fibered ropes.

The Cyclone 1 was incredibly fast, efficient, and back-drivable due to its minimal parts count and repair simplicity. It suffered from un-spooling when improperly handled with making this an unlikely candidate to be fully productized.

THE CYCLONE 2

July to September 02014

The Cyclone 2 was the design to commit to a small run of 500 units to donate to the First Robotics Challenge as a competing component. This design focused on eliminating common failure modes seen on the previous versions. Featuring a single motor, a simplistic gearbox, and the new anti-detensioning rail system that eliminated the de-spoiling problem when improperly handled.

The design was locked-in and local manufactures in Massachusetts were ready to initiate mass production but due to a skeptically high bill of materials price from the gearbox, plans were halted in fear of existential expenditures. Gears must be eliminated

Once the Cyclone 3 prototype was able to back drive and prove its efficiency as predicted, Arron, Blake, and Bill decided to fly to San Francisco for the 2015 Launch Festival to debut to the public a mechanism that the company could stand behind confidently. Our efforts payed off and received the Hardware Award. Investment alliances grew.


THE CYCLONE 4

April to June 02015

With new insights into high life cycle testing of the tensile element, a new Cyclone Cable Piston architecture is made. Using a new robust co-molded Kevlar and Urethane round belt with a more compact rectangular cross-section, the Cyclone leaves behind issues of frailties and becomes significantly more robust. Self destruction by end conditions is now a thing of the past. A smooth and fast operation with a recommended 75lb limit.

With the Cyclone Cable Piston component becoming stable enough to quantify, Rise Robotics can begin demonstrating its utility within an Application.

THE CYCLONE 5 PNEUMATIC PUMP RIG

July to September 02015

 The Cyclone Cable Piston can now push and pull with true backlash free properties. With this new architecture upgrade, we chose to cross pollinate this actuator outside of the Robotics space. Going after the existing pneumatic power tool market will be an excellent way to benchmark this new actuators abilities amongst existing products. First attempts were met with success when compressing a half gallon tank up to 100 P.S.I at 1.5 SCFM. Targeted to be a trim compressor, the cyclone also brings some unique benefits to the customer such as a lightweight structure with a quiet operation mode.
