there is some information in the tutorials section regarding calculating motor torque. search the posts and web as well.

a couple notes:
- what units is your speed in?
- you will probably need a gearbox (or some other speed reduction)
- what acceleration do you need?
- what surface is it driving over?
- does it need to go up any incline if so how steep?
- how much will the robot weigh (i'm assuming the weight provided is for the payload)?

speed is in km/hrs.
surface is ceramics/home tiles/wood floor.
i think i will be able to control acceleration with my aurdino.
not using robot for inclined surfaces yet.
total weight will be 10 kg of robot and the payload
Thanks for replying appreciate ur concern.
