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
PS, As this is my first post other than my intro, please let me know if this type of question is outside the scope of this forum.
Thanks in advance! (Hope some of you enjoy the video)
Thanks!
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.
Hey Putt Putt
Could you send me a email. I would like to discuss this further with you.
Thanks ... Herr
Herr Ball,
I sent you an email asking what you would like to know......but not sure if my email is working.
