Can The Ez Robot Board Directly Control A Wheelchair Controller?

Hi All,

New Builder here.

Does anyone know if its possible to directly connect the EZ Robot board to a wheelchair controller? I have a complete Pride Mobility Jet 3 wheelchair (used to be Mom's). I also have a life size Lost in Space Robot (aka: B9 Robot, aka: 'The G-bot') that my Son and I built a few years ago. While we have had much fun with it over the years, I was never able to complete his drive section and/or make him semi autonomous and mobile. Currently it has some animation and I control it (essentially manually) from a tethered pc.

I am very excited with the EZ Robot kit and have the G-bot dismantled awaiting his upgrades!

Of course $$ are not unlimited so I am exploring all options. I originally was planning to remove the gear motors from the wheelchair and purchase a sabertooth 2x60 motor controller to connect to the EZR. Of course researching that, the 2x60 sabertooth is not cheap and it occurred to me the chair has a controller but I don't want joystick control I want it integrated with the EZR. I am not sure if what I wish to do is possible or -if it is- if its within my technical capabilities.

Any comments, help or suggestions would be greatly appreciated.

Gwen

Gwen Attached some photos of joystick control by EZ-b

I extended the shaft using a box spanner( cut the handle off) ,fits tightly over original short joystick shaft and is held down by a simple plate with two screws.

Both servos are mounted on basic hinges which allow them to sway back and forth.

each servo has a long lever shaft one approx 1" longer.

Over time I have found it very stable and there is little load on the servos, with the extended shaft.

Hello Gwen, welcome to the forum. I would recommend removing the wheel chair controller and replace it with a Sabertooth Motor Controller. EZ-Robot and some kids built a robot from a wheel chair base for the Western Canadian Robot Games. It used a Sabertooth 2x50 and ran the motors with ease:)

There is support for the Sabertooth Motor Controller in ARC.

Hi Gwen,

A few questions, is your chair fully functional right now ( as in joystick controls works )

if so could you open up the joystick controller and send some a pictures of the insides.

I have managed to interface my controller and still have the chair working normally with the joystick.

It is a simple and inexpensive solution and uses existing hardware.

Dave.
