Need tiny tires for your robot? Make them from Sugru!

This instructable describes how to make custom silicone tires for a robot, connected together with an axle.

Materials for two tires, connected by an axle:

2 Dry Erase Markers (to use as a mold for the size of the tire)
Paper (for wrapping around the marker to prevent sticking)
Tape (needs to be removable, painters' tape will work well)
Popsicle Sticks (for molding and fashioning)
1 Axel (depends on the drive system of your robot, probably a wooden dowel will work)

Step 1: Prepare the 'mold' for the tire

Choose markers that have the inside diameter you want for your tire. 

Cut a paper strip to wrap around the marker.

Wrap the paper around the bottom of the marker, then wrap the tape around the edge of the paper. 

This will create a mold to use for the tire and spoke shape, and prevent the Sugru from sticking to the marker.

Mmm...I see impractical. <br>It 'really hard that the tires, at the end of treatment, have the same diameter. <br>This difference will result in a tendency to turn to the right or to the left and not to go right. <br>You could fix this by the driver sofware, but I see complicated and expensive... <br>What do you think?
