Step 10What's Next
Here is a very rough rendering of what I am working on.
This is a 2 person self balancing cycle. I have seen similar examples of this elsewhere, but mine is on a smaller scale. My goal is to make it very easy to make and cost less than $100.
It self balances because the weight is below the center of the axle. The pedals will connect to the wheels via chain. Each person controls one wheel. Pedal to together and you go straight. Go opposite and you spin in place, etc. I will probably make some form of disc brake for each wheel. Not shown are casters that will contact the ground to prevent rollover on sudden starts or stops. I am going to start at a scale for kids (about 5' tall max).
See the snapshot of the Sketchup drawing of the basic concept.
Here is a link to the Sketchup (Ver 7) file.
Update 5/3/09
Chip are flying. I cut one side, the seat bottom and the seat back. The size and fit of the seat was my biggest risk area. I used the Universe Cycle as a stand in for some pedals. The size looks good. It appears wider than I thought it would. To keep the costs down I am using BC exterior plywood. 3/4" for the sides and 1/2" for the seat.
I routed a lot of slots in the parts to give it a lighter look. It might save a little weight, but I think it will look a lot better. I designed some gears and a piston thing for the sides. See the new 3D view.
A lot of the mechanical parts are on order from Surplus Center. They should be here by Tuesday.
Update 5/5/09
Have the basic chassis cut. See the picture. Got the mechanical parts from surplus center. Added a picture of my shop.
