Hello All, I will be using this as my build log for my Lawn Bot. The plan is to build a bot that can haul a barrel, mow the lawn in summer, snow blow in the winter and preform a variety of tasks. the base will be a 24V jazzy wheelchair with custom frame. the brain will be the Jazzy VR2 controller talking to the EZ-b4 and what ever else i need to get it to obey my will. if anyone has done anything to feel free to chime in... I will not repeat NOT use a sabertooth controller for this.
Hope to update you all soon.

Have you figured out the jazzy controller protocol, or are you thinking of hooking up servos to the joystick? There is a reason peiple use Sabertooth and skip the wheelchair controllers. It is because the controllers are undocumented and indecipherable (seemingly on purpose).

you can find a TON of things if you look in the right places... I want to keep all chair functions so using a sabertooth is out of the question. I plan on following some of the steps outlined on a wheelchair forum to interface with the OEM stuff... well documented interfacing: https://www.wheelchairdriver.com/board/viewtopic.php?f=2&t=3790
Will you have an onboard PC so you don't have to worry about going out of wifi range or will you be using a wifi range booster?
That's great. I will be watching this one closely. I currently have Sunrise wheelchair motors and a controller, but they are pretty beat up, so I have been looking at maybe replacing them with Jazzy at some point since they seem pretty readily available. I do have a sabertooth, but keeping all options open, particularly since I keep coming up with ideas for additional robots I want to build.

@richard R I plan to have two options one is OBC(on board computer) the other is to use my cellphone and ARC.
Please keep us posted on your results. I tried for a long time to get my motors to work with the controller and EZB but finally gave up. I still have three wheelchairs here ... lol.
@Ted... you can grab yourself a sabertooth 2 x 25 if you haven't already done so and get your project up and running... I can help you with the sabertooth setup if you need it...
@V692 Most definitely, keep us updated on your project....
@Ted, If you are interested in selling (or trading for other stuff) one of the chairs (or just motors and wheels) let me know. I have a pair of Sunrise motors and wheels, but they are in rough shape, and missing some needed bolts (they were very cheap, so I don't feel too bad about the expense, but thinking about replacing them with something better for my first big project. They'll get used eventually).
My email is in my profile.
