Wheels for autonomous robot

[bnmitrobocon]

Hi,
We are a group of students from BNMIT, Bangalore and we are planning on participating at Robocon the coming year.
The problem statement requires that we build an autonomous robot capable of scaling an approximate incline of 20 deg and needs to have line following capabilities. Also the robot needs to have a usable payload of about 10kgs (total weight of about 20 Kgs) and needs to be fairly fast (read 10 m/s). We have searched a lot for the wheels and are unable to find any that suit our application.

Approximate specs of the wheels we are looking for:
a) Diameter: 12cm.
b) Needs to be able to carry about 10Kg.
c) Excellent traction

Any suggestions would be highly helpful!
Regards,
The BNM Robocon team.

You realize that your wheels will then have to go up to ~1'600 RPM?
