Mechanic part

[rickyzhang82]

Sorry, this is not an issue at all. But I have some questions on the wheels your built.

I'm building my own robot car by adding optical encoder in this motor wheel (http://www.amazon.com/Smart-Wheel-Motor-arduino-project/dp/B0081C5B80/ref=sr_1_2?ie=UTF8&qid=1389843011&sr=8-2&keywords=motor+wheel).

However, the motor is not powerful enough to carry my other stuffs. I need to re-build it.

The wheel you built looks quite solid. I checked your robot wheel in material spreadsheet. But some vendors eg. Ax-Man surplus store are not online store.

Can you give me more details on the mechanical design of the wheel? eg, the gear, shaft, encoder, hooking up and etc. Thanks in advance.
