- Here's a video with some details on how i hacked an electric wheel chair to be remote control with an audio and RC controller!
I've posted the code to github, don't forget to subscribe :)

This is really funny to watch as I’m in a powerchair full time. If my chair starts self moving I know who’s to blame! 😂
Glad you enjoyed it!
Would love to have a parts list and wher to get them and an instruction manual to do this? I am handicapped and in powerchair. Could use this to get my powerchair out of the van with a lift in it?
didnt mean to blow up the thread just happy to have found someone in similar situation making progress , I actually bought new brushed d.c. motors to get the lawnmower going but still want to use the brushless invacare motors Im just need the info and maybe someone to bounce Ideas off at times
Hi voiceofreason, not sure how much help I'll be. Here's an article on brushless motors you may find useful www.digikey.ca/en/articles/techzone/2013/mar/an-introduction-to-brushless-dc-motor-control In my case, I faked the joystick inputs to the chair so I could use the Invacare motor controller. Let us know how you make out.
sure thing thanks for the re[ly my names joe I know thats easier to type I will read but if you get a chance can you give me model number of your controller the one before the joystick and probably to the arduino If in bit being to confusing ? The reason i ask is What i have found is that it may be easier to use the chair motor controller as the PWM at first at least to get it running But maybe this article above will give me better info I know i should have paid better attention when I ordered these I thought they were regular two power wire brushed DC motors like the other 99.9 percent thanks Grorange
I know this is an old build, Any chance I could get the code you used for this?
Can't figure out how to send a pm but I am trying to do the same thing as you did here, just wanted to see if I could get more details. I have the motor controller but no joystick. Managed to jump the pins and get into attendant mode and move around just has very limited speed
You didn't by any chance make a video of when you converted your chair to rc, so to see exactly how and what you did.
Oh please tell me I have this problem right now same deal rc lawnmower bought motors off ebay ended up being brushless dc
Did you ever get this project turned into a RC Lawnmower?
No, lost motivation and sold the project. Not sure how the next owner made out.
When you put back together
Video your setup so we can you wiring better. Thanks
Sean, Do you think you could “adapt” this to a functional chair. I have a friend who would be elated if he could “command” his power chair remotely while he is performing various tasks. -And I would venture to guess there is quite a market for such technology.
That’s an interesting thought. It’d take a lot of development, but I don’t see why it couldn’t be done. The chair I was using had a wired remote accessory for “vallet” mode. I wonder if the chair makers would consider a wireless version? Sounds like a smartphone app to me!
Grorange Garage, Great information! I will see if my friend’s chair includes the vallet feature. Thank you for the feedback and good luck with your endeavors. 👍😊
I have the same motors can I bypass and just use a 12x25 motor controller, cant seem to find any info on this, is there brakes on these motors that have to be removed. I'm not much on electronics so if you could point me in the right direction.
If you have the same chair as I do, it has brushless DC motors. You won't be able to control them with a standard DC motor controller. The electronics required to control brushless motors are a lot more advanced and difficult for a DIY. I'm not 100% sure, but i believe the brakes are also part of the motor assembly. Hope that helps.
Could you tell me in depth what I need to buy and where to buy them? I am wanting to build a large scale RC army tank. I have 3 wheelchairs but i don't know how to wire it. I am also trying to use one of those motors for my sons bike. I bought a throttle for a motorized scooter on ebay but I couldn't get it to work. someone told me I needed a speed controler but i'm not sure which one to buy. Thanks.
Hi dahc, what you need to buy will depend a lot on what you're starting with. If you're using brushed DC motors you'll need to build or buy a driver that can handle the current. The sabertooth drivers are pretty popular. If you're using brushless dc motors like the unit I used it's much more difficult. Your best bet is to run a few google searches on your particular wheel chairs. There's lots of guides out their for the different units.
Thank you Sir.
I got no controller dont even know which kind to get 5 hall effectsensors and 3 power wires
Why add the 4.7 kOhm resistors, cant you just modulate the voltage/current with the microcontroller?
This may be a really silly question, so if its obvious forgive me.
That’s a good question. To be honest I don’t recall why I added the resistors... The Arduino is effectively pulsing at 5 Volts at a frequency to give you the desired “average” voltage - say 2.5V. The capacitors help to dampen the pulses and are necessary to keep the chair controller happy. Not so sure about the resistors...
@@GrorangeGarage Huh, well im working on a very similar project right now.
I'll attempt without resistors and see what happens.
I'm also gonna use a board with more interrupt pins to make my life easier looking at your code.
I’m curious to know how it works without the resistors. Only thing I can think of, is it might draw too much current from the Arduino without them.
@@GrorangeGarage So you happened to be right, it was a but funkey until I added some 5kOhm resistors as I was drawing way too much power.
I'm now curious why you chose pins 7 and 8 for input as they lack PWM on the uno right?
Wouldn't that make your life easier as you are going digital-> analog?
So, it’s been some time since that project. I don’t believe a PWM pin offers any advantages when reading a PWM signal. However, it looks like I may have been able to simplify my code using the interrupt pins 2 and 3. Here’s an article on it:
www.benripley.com/diy/arduino/three-ways-to-read-a-pwm-signal-with-arduino/
I just saw your video and loved it I have a wheel chair alot like yours but mine has brushed motors. Will your code work and if so could I please get a copy. I tried to PM you but cant figure out how
Hi Furry, hard to say if my code would work, it depends on the chair. If your chair has brushed motors you may want to consider using motor drivers. Sabertooth drivers are popular for this application and will be easier to control than the method i used. They can be used directly with a rc controller, no need for an arduino. Here's a link to one: www.dimensionengineering.com/products/sabertooth2x60
can you give me the controller info please ?
Any info on rc receiver two wire?
Here’s what I used:
1x #TX-9X-M2/8992 Turnigy 9X 9Ch Transmitter w/ Module & 8ch Receiver (Mode 2) (v2 Firmware)
Awesome proyect,Would share your arduino code?
Hi Carlos, if you send me your email via youtube message I'll send the code and libraries i used.
Would you be willing to share your code for the arduino?
Hi Chad, if you send me a RUclips message with your email I'll send it.
Did you use MOSFET?
No mosfets on this one. I replicated the jolly stick input so I could use the chairs existing motor controls as this model used brushless motors.
Did you ever finish your rc lawnmower project and can I have the arduino code?
Never did finish the project, happy to send you my code. Just not sure how to get your email without it ending up on every spam list out there.
Posted to github, good luck with the project and please subscribe: github.com/Tinkertann3r/RC-Wheelchair
please send me the code for this project

Kilohertz resistor😂😂😂😂😂😂😂😂
Would you be willing to share your code for the arduino? your experiment is so great !! I think I will making an experiment too, and use your way to "hack" zhiyun crane 3 axis gimbal joystick, because this gimbal don't have a RC input :)
Hi Andi, you should have the code (emailed from shawn@sharklasers.com). I've deleted the comments with your email to keep it of of spam lists.
Grorange Garage Hi..thank you so much for your codes!, I hope I can use it for my next project :)
and if you did could you post it
Hi Christopher, unfortunately that's the only video I created the wheel chair. The basic information is in the video, including the electronic circuits. The only thing missing from the video is the Arduino code for converting the RC signal to the appropriate output for the wheelchair controller. If you message me your email address (don't post it here) I can send the arduino file and libraries i used.
@George can you share with me at aibuzghaffar@gmail.com
killlllller if you don't mind I would also like your code
Just need an email address to send it to (send via youtube message) and would appreciate a subscribe!
