Rehabilitation Robotics; STRAC, Symbiotic Terrain Robotic Assist Chair;

For Paralysis Victims. Designed & built in 6 weeks in 1999.











In 1999 STRAC was designed and built in 6 weeks. It was one of the select few Rehabilitation Robotic Prototypes that were demonstrated before the "International Conference On Rehabilitation Robotics" "(ICORR)" at Stanford University, in California.

STRAC, stands for Symbiotic Terrain Robotic Assist Chair.  Although STRAC, features some of its predecessors functions like artificial touch, artificial instinct and facial feature controlled actions, its improvements include Self Therapy. It may also be the most powerful wheelchair ever built. It’s base is an all terrain design that is strong enough to pull a car.  STRAC, is capable of climbing hills, curbs, and can tilt itself to compensate for the  slant of the ground, raise and lower the patient, speak to the user to inform about its current status, sense the patient’s facial movements & react to those movements by creating appropriate actions in its autonomous base and two exoskeleton arms and metal fingers. It also features an automatic navigation system that can “see”  in light or dark to assist in avoiding obstacles.  The chair sees using short bursts of ultrasonic sound bounced off objects to judge distance. STRAC also has an improved pen attachment that allows better reach and  more dexterity when drawing and writing.  The chair operates on 24 Volts.

STRAC uses 3 or 4 facial feature movements to utilize 40 different basic functions which is expandable to hundreds, while relating it’s status through a visual indicator console. In practical terms this design is easy to control and allows multitasking. An Adaptive Tech example; a person can easily control a five range of motion robotic arm on a robotic wheelchair base entirely through the use of moving their eyebrows and nostrils alone. This enables them to maneuver around a room in any direction, pick up and move objects, and print or draw on a vertical surface.

STRAC’s, wheels are unique triangular multi wheel devices, designed to climb uneven surfaces. The idea behind STRAC, is to give paralysis victims hands on interaction with their environment and the durability to challenge the outside terrain.

STRAC, also sends information about it’s status to the patient by beaming it into the top of the lens of the eye. There is no need to look down at a control panel which had been a short coming of the original chair. STRAC’s  console is always a glance away and held in permanent focus to the patient’s eye.


STRAC II, was designed in 1999, however its completion date is dependant upon available funding. It is a streamlined, light weight version of STRAC.  STRAC II is forty percent lighter and has increased dexterity and modes of operation.  The ultimate design will literally form to the patients body, has self therapy applications and is light enough to easily handle.



We purchased a 36,000sq.ft disused school on roughly 10 acres on the plains of North Dakota and are transforming it into a Prototype Environment for a low cost, low impact, self-sustaining, alternative energy powered, Humanitarian & Environmental Research & Development institute with a Think Tank and Invention labs, in a Zone 3 growing area. Our purpose is to invent and present responsible, low cost and easy to implement, beneficial humanitarian and environmental based technologies and methods that assist with social, ecological, sustainable and economic solutions. Accomplishing the prototype environment alone requires research & development of new technologies & improvement of existing technologies. To help fund our R & D part of the Institute will be used as a World-Class “Interactive, Hands-On, Robotics, Technology, Invention & Nature Center” that will feature our standard line of World-class exhibits and Showcase our Private Collection of Innovative, Interactive Exhibits & Devices. It will also incorporate “Responsible Technologies”! Admission will be free to the underprivileged.
