Another Servo Voltage Question
Archiver
Posts: 46,084
I asked one a few weeks ago, and thanks to everyone who responded. I
have 2 servos hooked up to a BoE, which supplies the unregulated
battery voltage to the servos. I'm using the 2 servos to move the
robot and I was curious if different changes in voltage would have an
effect on the distance the servo travels. For instance, here is some code:
uturn:
for x = 0 to 330
pulsout 12, 1700
pulsout 13, 1680
next
return
At the moment it makes a u-turn. However, the batteries will slowly
drain. So will that code make a u-turn for my robot at 6.5volts and at
6.0 volts? Thanks!

a certain distance over the life of the batteries.
Your options include:
Wheel encoders
Monitoring the battery voltage and working up a table of values at
various voltages
Turning based on other input (wall sensors, external encoder, etc...)

voltage available which is higher than what the servos
require say 12 volts then use a 7805 regulator (5
volts) to supply power to the servos.At least you
would always be working with the same voltage instead
of having a drop when one servo is running then trying
to figure the voltage available for the other servo.
Sorry I didn't read previous posts about this.
