Hi, can i know where can i get websites for the speed-torque graph of a DC motor? The motor is just a simple one, those that can be bought cheaply off the shelves..
Also, suppose i use a DC motor for my robot, how can i change the direction of the motor's turning? I am not supposed to control the robot manually once it runs.
Lastly, does the gear ratio come into the picture in calculating power needed in cells? Suppose i already have my output power calculated, and gears would be used in transmitting the power to the motor, do i have to use the gear ratio when calculating power supplied by the batteries?
a) if gear ratio is needed, how do i use it?
b) if gear ratio not needed, is it used in any part of calculations? or rather, when do i need to use gear ratio in the calculations?
Eerr... in formal calculations for robots, after calculating the output power needed by the mechanism, what are other aspects of calculations do i need??
Appreciate any replies posted
