Agnes is a little, vivacious dog from Ukraine. Unfortunately, she is seriously ill. Agnes suffers from polyneuropathy - she can’t move on her own. Animal foundation „Węgielek” decided to help the dog and asked student organization „Biokreatywni” from Silesian Institute of Technology to design a special wheelchair in order to give her a happy, healthy and active life. I became a person responsible for designing and constructing it.
There are many dog wheelchairs available on the market. Unfortunately most of them are made for dogs with weak hind legs and are no use to Agnes.
This is my first instructable. Unfortunately I decided to write everything down after creating the final version of the wheelchair so I don't have any 'in progress' pictures. I'll try to explain everything as clearly as possible.
My dog wheelchair has a very simple design. Materials used to create it:
- 5 aluminium pipes, 25 mm outside diameter,
- 4 aluminium pipes, 12 mm outside diameter,
- 4 wheels (two of them are swivel)
- various screws, nuts, pads, rubber caps,
- 4 aluminium clamps,
- 8 plastic buckles,
- material for special harness.
The picture shows some of the crucial elements and tools used to create the wheelchair.
Additionally, I designed special mountings which were 3D printed. They will be described more fully further. I also needed some sewing materials, like straight pins, a pair of scissors or a sewing machine.
Agnes is quite a big dog (12 kg), so I decided to use a little larger wheels (200 mm diameter). They were taken from a used baby stroller.
