hi, im new to this site and wanted some advice or help! i am building a robot form wheelchair parts, ie, im useing 4, 24volt motors, 2 motor controllers and wanted to wire it all into 1 joystick, ???? can this be done?  any advice or help would be a great help. thanks

waltr:
Which controllers are you using? Link to data sheet.
Do they have resistive control inputs?

What function do you want the motors to do when the Joystick is non-centered?

This would be fairly easy to do using a micro-controller. the joystick's two pots feed a variable voltage to the u-controller's ADC inputs. Then based of the measured ADC values send info the the motor controllers.

joefish41, if you also got the controller(with a joystick) that came with the motors, you could use that.
the sweet thing about using wheelchair controllers is all the built in safeties.

hi guys, thanks for the advice, the 4 motors, 2 controllers and the 1 joystick came from 2 identical wheelchairs they are quite old controllers and joystick, they are penny + giles d49464/5 controllers, what i had planed to is use both controller, with both the wiring looms from the chairs  and wire the looms into 1 joystick, speed control  but i wasnt sure if this would work? or if the 2 controllers would be to much for the 1 joystick, speed control, im not that cleaver when it come to electronics as i am new to all this kind of stuff???

joefish41, if both controllers share a common power source I could see it working(IMO 90% chance).
 the P&G controllers are programmed for a particular acceleration/deceleration and speed profiles for
different users, chances are your going to have to have them reprogrammed to operate the same(cost me $50.00Us).
