[typo]’s mother gets around with a walker. It’s a great assistive device until she has to lift the heavy thing up into her car. Noting that this was a little cruel he did as any hacker would and found a way to automate the process.
The build is pretty cool. She had to give up her passenger seat, but it’s a small price to pay for independence. He removed the door paneling on the passenger side. Then he welded on a few mounting points. Next he had to build the device.
The well-built device has a deceptively simple appearance. The frame is made from CNC milled panels and the ever popular aluminum extrusion. It uses a 12V right angle drive and some belting to lift the chair. There’s no abundance of fancy electronics here. A toggle switch changes the direction of the motor. There are some safety endstops and an e-stop.
Now all she has to do is strap the walker to the door. She picks the direction she wants the lift to go and presses a button. After which she walks the short distance to the driver’s seat, and cruises away.
