I got these Pittman motors GM9234S022-R1 from ebay (4 pcs for aprox. 120$) from a shop called raysnow. The gear ratio is 38.3:1 which gives 127 RPM.

My plan is to use standard differential steering with driving wheels from a kickboard which have excellent high friction and good stability with double ball bearings and they are cheap too. Standard diameter off kickboard wheels are 12cm.

The speed of the driving mechanism will be around 80cm/sec with no load and i guess when i put a 25-30kg robot on top of it the speed will be reduced.
