DIY Electronic Controlled Motorized Wheelchair

My wife is having ankle surgery, and will be in a wheelchair for three to six months. This will literally be a lifesaver. Thank you!

I just got my chair… I was told that I am too heavy for a motorized chair 🤔🤔 (but not a chair “I’m only 380” /6’-6”H). My chairs support weight is 700. I’m an Arduino junkie…. You my friend just gave me a grand foundation to build on 🙏👊👊🤙 Thank you. And yes.. I’ll refer back if the build goes well.

Thank you for your resources and the time that went into this you can’t imagine how much this is going to change my life.

I't looks like you used digital switches for the movement, i'd go analog using an RC car/helicopter/airplane gimbal joystick. Adjustable speed and far more control over turning.

I was thinking you could put the rollers below the frame in front. To help with the added weight distribution. Also, you already have a good mount point there and might need as much added structure.

I know sealed lead acid batteries are the cheap and easy solution, but you do realize you can only use about 3.5 Ah (50% of rated capacity) before before starting to reduce it's lifetime significantly? A lithium-iron battery would be a direct replacement, have longer (2-3x) lifetime, and let you use much more of it's rated capacity. Bass Pro Shops*** sells the Tracker LiFePo4 battery that would be a drop-in replacement for the Genesis (as would a lot of others). The 6 Ah version would be about 3x the price of the battery you chose, but have at least 50% more usable capacity per charge, and a much longer lifetime (500-1500 charge cycles vs. 200-300). Not only that, partial charge/discharge cycles actually extend the life of LiFePo4's. Doing the same to Lead Acid will lead to reduced lifetime. Storage presents similar problems - Lead Acid batteries sitting around doing nothing degrade much faster than Lithium Iron - especially if partially charged. And if you upgrade the charger as well, it'll charge a lot faster! If you're only using this enough to replace the battery less than once per year, it's probably not worth upgrading. Once per year or more, and a LiFePo4 will save a decent amount of money. ***Disclaimer - I am not a Bass Pro shill, nor do I advocate them or Tracker batteries over any other. This was just one example from many that would work well, chosen for being well known and available in a lot of areas in the U.S. Tracker batteries have a 2 year warranty, so I 'assume' (don't! :-) they're decent. YMMV. (Also, I personally like being able to talk to a human, in person, if I have issues after the sale, so I buy local whenever possible.)

You're awesome! Great work.

Thank you so much. So good idea. I got some idea to make my own.

Now this I would personally love to have for myself

Sir, can you advice me on how to upgrade my electric wheelchair to run a bit faster and stronger safely? My wheelhair has two motors. Each has 250 watts. It has 2 batteries as well. Both are lead acid with a capacity of 12v 17.2ah each battery. Do I need to change my controller as well? Or is there a significant upgrade that won't be needing to upgrade also my controller? This is the keywords in Amazon 2021 Model Fold & Travel Lightweight Electric Wheelchair Motor Motorized Wheelchairs Power Wheel Chair Aviation Travel Safe Heavy Duty (Red - Black). Hope you could help, Sir.

Nice video. Thank you

What I would change - I'd relocate the drive motors back lower on the wheel and I would move the Power Switch to the armrest and I would have it a key/ignition switch. It would also be helpful to have a power meter where the person in the chair can easily see it. Wishlist item - Some sort of cordless charging dock.

This looks awesome. It will help a lot of people who can not afford a motor wheelchair. I was curious over time the little motor hub wheel being plastic how long would it last? I would think over time it will wear down.

could you please explain about the what type of controler,battery,and motore.

you reversed the 3 pin standard for wheelchair charging. Pin 1 is +ve, pin 2 is -ve and pin 3 is usually inhibit (connected to pin 2).

Hey element, what sort’ve 3d printer I should buy for a project like this ?

Have you considered modifying a hoverboard to be controlled by a joystick and then attaching it to the wheelchair in some way?

And some tweaking to the idea can make it more versatile

Nice 👍

Hi is there a way to do this without the joystick? Just make the wheels motorized themselves?
