This continuing need is detrimental to anyone with a limited movement, which forces them to occupy a wheelchair and rely on others.
An electric robotic wheelchair saves energy and make things possible for people with varying mobility levels and special needs. It has made its impact over the market which doesn’t seem to get replaced by other alternatives anytime soon. Factory wheelchairs might come with different settings for a person who wants to do something more than just using it for the ease of mobility in their daily life.
However, modification is a vague term, it could include all sorts of modifications. As for wheelchairs, it can be defined as modifying the wheels to make it go through some challenging terrains, modifying the battery for optimum life, the seating position or using A.I robotic wheelchairs can be made to self- drive.
Developers never let their minds go in vein. They are always looking to manufacture new and innovative products. By using a few distance sensors, a few cameras and a board (Arduino etc); A.I can help build a robotic wheelchair which doesn’t require the person to push or handle it. It will go where it’s told to through voice commands.
Another type of robotic wheelchair, a less complicated one, can be made using a distance sensor and a few cameras. It will not need the user to push it. It will follow the movements of the user's shoulders. Camera and distance sensors work with a pretty impressive response time, allowing the user not have to wait for the wheelchair to respond, it responds as soon as it gets the signal, without any delays.
It can also be made to follow its user by mimicking the movements of that person, wherever he/she moves, it will follow them exactly. Each move will be instantaneous and it will not make the user wait for the robotic wheelchair’s response. Generally, such settings are made to keep the wheelchair on left side of the walking companion.
Using such a system will have a lot of advantages. Some of the advantages of using this customized wheelchair is obstacle safety. The person riding it does not need to worry about the obstacles as the wheelchair will avoid the obstacles on its own. Obstacles even include the moving things, like a human being. The robotic wheelchair will itself choose the path that has lesser obstacles in.
What parts are required for Wheelchair Conversion?
For making this project a reality, both electrical and electronic components are required to be modified accordingly. Some of them are briefly described below:
In-wheel motors: Most 250-watt motors are gear-wheel motors, meaning they have planetary gear reduction, so the motors rotate at the best RPM. This makes the motor more efficient than a simple direct drive, 250 watts hub motor. Planetary gears mean higher torque and more efficient electric motors. In the motor shown below, you can see planetary gears that make the motor rotate 5 times faster than the wheels. Because electric motors like fast RPMs (more efficient, more torque, and more reliable), planetary gears allow smaller, lighter motors with the same output power as larger motors. By weight, a gear wheel hub motor is much better than a direct drive wheel hub motor. Although some companies produce 250-watt direct-drive motors (such as Bionx's 250-watt motor, which is the same motor used on smart bikes). We strongly recommend that you purchase a bicycle with this motor size and choose a geared hub motor over a direct-drive hub motor as they are lighter, smaller and more efficient. Like most in-wheel motors today, 250-watt motors on the market utilise efficient brushless motors.
