I am using a roboteq controler SDC2130 to drive a differential mobile robot.
Motors are DC Motors with a 71:1 gear box and a 7 Pulse per resolution encoder.
So taking into account my gear box, I have a 71*7 = 497 Pulse per Wheel resolution.
I need to be able to move slowly at something like 0.22 wheel revolution per seconds. (105 pulse per seconds).
I read that the internal control loop of my roboteq controler is at 1Khz (1 pulse every 10 controler loop !).
So my question is : Is there a minimal pulse count per controler loop ?
Or in other words : What is the relation between the speed accuracy, the control loop rate, and the pulse per revolution ?
