Wheelchairs having automatic prime movers were wrongly referred to as automated.
However, modern wheelchair designs have dramatically changed, making a revolutionary product development beyond imagination.
As per the latest trend, an automated wheelchair is with guide sensors, nonlinear signal processing circuit, pulse-steering drive and so many other controls for smooth move.
They are designed to suit indoor and outdoor application.
To ease the convenience of the user, push-button switches are given involving simplicity in operation.
This sophisticated equipment is more intricately designed with great complexities; yet quite user friendly for the rider.
Normally designed to move over a level contact surface, automated wheelchair comprises of an operator-chair for the user, two wheels for propelling, a programmable computer to control, an input device for operator to give commands which will be transmitted to the computer, set of extendable and retractable spokes that are part of the main wheels, group of sensor devices attached to these spokes that send signals to the programmable computer, several motors with sensors to respond to these signals for input as well as output signals to and from the computer and overall coordinating controls to connect with the commanding center of the controller.
More than two million Americans use wheelchairs and it is estimated the demand to grow multifold.
This expectation has motivated for more sophisticated developments upgrading the automation in automated wheelchair industry.
However, in spite of recent developments in technology, the modern wheelchairs are still incapable of meeting many requirements of the user's expectations and needs.
There is a constant demand for more options and better maneuverability with better performance capabilities.
For example more and more models are coming to transact steps and stairs of various types, measurement and styles like regular, spiral and complex.
Now wheelchairs can climb up staircase and can climb over most types of landscapes with ease.
Some models of wheelchairs allow the users to stand up and reach the highest cupboards in the home.
These days' automated wheelchairs are coming for rough outdoor use also.
They are not only sturdy but also very user-friendly.
The predicaments of the handicapped operators are taken into consideration for constant developments and up gradation.
In addition to the function that provides braking system, infrared sensors are incorporated to suddenly stop the wheelchair against a collision.
While improving the functionality, safety also is given prime importance to transact any emergency while the wheelchair is moving at a top speed of about eight kilometers per hour!
