I was wanting to know that would a feedback control loop be required to be attatched with each of the four servo motors ?
Secondly the electronics of the robot. has not been explained on the website I would be thankful if I could get some help in this regard
I connected a HS-311 to a signal generator and gave it a square wave (0-5v) at different frequencies but I did not get a good range of speeds.
And another problem was that two different motors did not give the same speed for the same frequencies. How to go about this??
I shall be grateful if you could explain to me how you managed to control the movement of the robot like spin, movement at different angles etc...
What do u mean by "angle_of_wheel" ?
How did you measure the servo speed?
bcz for correction of speed I would need to know the current speed and then compare it with a reference value then change the duration of pulses accordingly??
Would you recommend using DC motors or stepper motors with an H-bridge drive instead of the servos??
I was using the high r.p.m HS-925 mg today with a power suppy and signal gernator but it was drawing 2A when stopped.
my robot used sensors to correct for speed error
Quote my robot used sensors to correct for speed errorWhich type of sensors did you use.... The only way out that I see is to use an optical encoder...Is there any other way besides that??
