I have started a major project “WHEELCHAIR CONTROLLER USING HEAD GESTURE” .
Can any one help me with the specification of DC Motor and other specifications.
I want to use Rapberry pi and what all sensors are required for the same so.
Ideally you would start with a used motorized wheelchair rather than adapting a non-motorized one. A manual wheelchair’s wheels don’t have any evident way of driving them via DC motor, so you’ll have a lot of hacking to do. Before starting, check local “for sale” sites like Kijiji to see if you can get a used power wheelchair or even power scooter and use those motors, the controller and battery. If not, you’ll actually end up spending quite a bit on brand new motors, controller and battery. For example, moving a person up an inclune takes quite a bit of power and you would need something like 2x of these gear motors:

These take power controllers and large batteries. For example:

Once you have motorized the wheelchair, you’ll need the sensors, and an IMU can be used for head tracking.

A Raspberry Pi is not necessary. You can get away with using a normal microcontroller like an Arduino:

Thanks CBenson Admin,
Can you also give me insight about battery . Is it possible to use 7.5 v 2amp battery * 4
The battery’s voltage should correspond to the motor’s nominal voltage.
For example if your motors operate at 12V nominal, you should use a 12V lead acid, 12V NiMh or 11.1V LiPo battery pack.
It will need to be able to discharge at the maximum current needed by both motors.
