Ron Perranoski ITMG

Robotic suit, built by Argo Medical Technologies, ltd with the purpose to allow paraplegics to walk again.

Connected to the harness and the leg braces is a computer, which is located inside a backpack User is strapped into a harness and to two motorized leg braces.

 Attached to the users wrist is a remote control with five settings: standing from sitting, sitting from standing, walking (fixed pace), descending (stairs), and climbing (stairs.)

 The user holds two crutches to move their upper body. (Upper body mobility is required to use the ReWalk.) Motion sensors placed in the chest and torso region detect the change in gravity, movement, and direction of the body.

The computer takes the information picked up by the sensors and computes the motion that will be taking place, depending on which setting the user picks.

 The computer then sends the message and directs the legs in the way they need to function.

ReWalk ComponentsFunction Backpack Computer Backpack holds the computer Computer calculates how the body of the suit should move, based on the body position and movements detected by the motion sensors Motion Sensors Placed in the torso/chest region of the harness Sensors contain three axes of angular rate sensing and three axes of acceleration, which gives a precise area of where the body is in space and at what speed and direction it is moving Motorized Legs Composed of DC motors at the limb areas Strong enough to support weight of body Move according to the function directed by the computer

ReWalk Components (Continued)Function (Continued) Crutches Held by the user Moves the crutches to change upper body position and gravity Wrist remote control Used to select which setting to use Settings: standing from sitting, sitting from standing, walking (fixed pace), descending (stairs), and climbing (stairs.) Harness Connects backpack computer and motorized legs to body Batteries Easily rechargeable/accessible Power the ReWalk

 Wheelchair users suffer from an array of problems: urinary, respiratory, cardiovascular, and digestive system problems, as well as osteoporosis, pressure sores and other afflictions.

 Even by just being guided through the motions with the ReWalk, it will lead to better overall health and fitness and will even amplify bone density.

 The ReWalk cuts costs of health care through complications caused by wheelchairs and equipment used to help mobilization, (bed lifts, standing devices, etc.)  These health care costs can save someone tens of thousands of dollars annually.

 With new technology comes flaws: - Daunting appearance - Instability on unlevel surfaces - Limited to people without control of only their lower bodies

 The first cell phone was  created in 1973  Cell phones Today ReWalk Today ReWalk in 40 years?

 Argo Medical Technologies ltd believes that the ReWalk will be available for the public before the end of the year  The price is estimated to be around twenty thousand dollars, but when you subtract the price of annual health costs without it, it will balance out, if not, save the user money.
