The weight figure is only approximate . The motors itself would come around 200gms each .And with batteries and chassis i'd say the figure is very realistic .
And u say tat i need to get stepper motors with a gear box?? Haven't seen anything like that yet. (MAN !! Its a pain in the a**
getting parts here in India.)
My knowledge about steppers is very limited which brings me to this question.
Does motors with high voltage means high torque or with high current rating means high torque.??
I got a motor with the following specs :
4.2Volts, 850mA per coil, Unipolar , 3.8degree step angle .
Will this produce enough torque. ??
