An idea set in stone

So we have been busy at work on this project. We have managed to get together a couple times and boil everything done to what we are using for parts. We also have plenty of pictures.

This is a power source we hope to use. It came out of an old car that was not in use anymore. We hope that it can still hold somewhat of a charge.

We found 2 tires that came off an old bicycle. 

Caster wheels for the front of wheel chair

These movable bearings were purchased from a hardware store.

The motor that we ripped out of the poor treadmill. The pulleys you see on the left were also bought from a store. It took a long time to find a small pulley that would give us decent torque. That was the smallest we could find without spending too much money

This is just an overview of the gutted treadmill. We took a lot out of it

The top picture is the internal power supply that came with the tread mill. The picture right below it was the motor control unit. Because this treadmill is so old, we don't know if we can use this at all, but we can try.

Here is just a mess of everything else that we have been working on. All of the wires and soldering that have been going behind the scenes of the project. 

So here is what we have so far. As you can see in some of the pictures, the frame itself has already been built. Regarding the axle in some of the pictures, one of our group member's, Dean, machined the axle himself and had it threaded. This allowed us to lock the tires in and help give it a stable ride when we do some actual testing.
