This object is designed to primarily help those who do not have great movement with their forefingers and thumbs, forming the famous forceps and use a motorized chair . This was inspired from my own needs when I got a motorized chair, last year.
The motorized chair that I use came only with a joystick model in pyramidal (conventional) shape . However, for my needs, this format is not very functional , since my forceps movements are limited , difficulting to control the chair.
So, I developed a joystick model where I hold it with my whole hand to have a better control (speed and direction)which makes its easier to use.
The model was designed in Solid Works and the measures initially refer to the size of my hand.
