ScottCar A Go-Kart for a special child

Description

I build this car for our autistic Son. Scott has 11 years now and he loves bobby-cars, but he is too tall now. A go-kart is not an option, because he does not know how to handle pedals and brakes. So I decided to build something between both cars.
He can move forward this design with his feet, like a bobby-car. In case it goes downside hill, the car will detect the speed and slow down automatically with an electric braking system. In case of emergency you can use the remote control to stop the car.

This weekend I finally found the time to cut, drill and screw the first parts of the frame.
Looks promising.
Finally the first results

This weekend, I found the time to work on this project. The first aluminum parts are finished.
More pictures will follow.
The wheels

I will use 400mm wheelbarrow wheels for the go-kart. Now I have to find a solution to attach the brakes.
First aluminum profile
Alain Mauer • 04/29/2017 at 18:42 • 0 comments

Today I found 2 aluminum profiles. They have a length of 2m. The dimensions are 40mm x 20mm x 2mm
Now I need to buy 2 profiles of 30mm x 30mm
Shock absorber, Brake discs and the H-Bridge parts

Finally the parts are here:
The motor and the first parts

For the brake system I will use this Motor from an old project of mine A motor with a screw drive. It's very strong and fast enough for my idea
For the controller, I will use an Arduino Nano and a breadboard for the hbridge.

Best wishes to you and Scott, I hope this goes smoothly and works out well for him. Thats going to be a special gift for him, he's a lucky boy to have a dad who can.

Good luck :-)

Thank you. We try to help him and us, as much as we can. I just finished his new room, with a modified bed, camera system and his ScottTv.

Thanks a lot. Comments like this makes us happy. I've already started to organize the material. Hopefully I can start in the next 2 weeks with the build, so the car will be finished for Scott's birthday by the end of June.

Regards

Alain
