Rehabilitation Robotics; Artificial Autonomics & Robotic Interface, For Paralysis Victims
Designed & built in 1998, in 2 weeks.
The robotic chair above can operate a five range of motion arm, move objects, draw on paper and maneuver around a room by sensing three facial movements. In theory and in practice the chair uses a custom designed control console and unique Boolean matrix to control fourteen separate functions.
This prototype was chosen to be demonstrated before the
"International Conference On Rehabilitation Robotics"
"(ICORR)" at Stanford University, in
California, on July 1999.
Feature Controlled Wheelchair
This experiment uses only three
facial movements to utilizes fourteen functions that control a five range
of motion robotic arm and a mobile wheelchair base, while relating it’s
status through a visual indicator console. This design is easy to control
and allows multitasking. It maneuvers around a room in any direction, can
pick up and move objects, and allow the user to print or draw on a vertical
surface with primitive strokes. We condensed it’s circuits
and power distribution by designing an unusual circuit which takes simple
signals from sensors on a patient’s face and integrates them through a
matrix of wires, relays and electronics which relate Boolean logic
and power distribution in both directions and on one set of common paths.
Next Phase Wheelchair
The exoskeleton design redefines the concept of earlier experiments by reconfiguring the unit to appear to fit like armor without the drive components being directly visible. As illustrated this design would reduce the bulky look associated with such concepts . Each range of motion would have both mechanical and electronic limits to insure that hazardous over travel in a given range of motion does not occur. The design would embody the concept of an artificial motor control and instinctive reactionary system, that links to a patient’s features.
Preliminary experiment was successful.
In each design the challenge in configuration is the inability of a patient to easily convey enough motion request data to the artificial system for fluid movement and quick action. To accommodate this problem, modes of operation can be designed to take care of known factors of movement relating to the surrounding environment. A mode can for example be balancing a glass of water, performing an emergency action to avoid tipping, calling for help if the patients vital signs are questionable, calculating climbing angles for rough terrain, navigating towards an object, shaking hands, etc.
We distribute functional limitations across a robotic device to increase the chances of safe operation. For instance limits and simple logic circuits relate positions of arms and will not let them travel beyond a safe point regardless of what the main circuit board tells it to do. I believe that robots would ideally have their “Electronic Brain” spread out across the entire robots body, freeing the main boards to imply actions rather than being the total governing discipline.
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.
