the servos on stampy the sumo robot are they modded so they are one of those 360 degree turn servos?
yeap, they are modded for continuous rotation
wouldn't a motor on its own also be able to do the same job as the servo or was the servos used because they can turn foreward and backward without the h-bridge
motors will work too, and could probably go faster. however my limitation on speed was determined by how fast the scanner could get a reliable lock on a target, and servos made that easier to do.
but i also had two other limitations:
- i wanted to build the robot with as little effort as possible, and servos are reliable prepackaged solutions. i own wired up motor drivers, too, but i didnt want to bother figuring out PID control or using encoders. as a result, that robot took me only 25 hours to make . . . ~10 hours of it correcting dumb mistakes . . .
- i already owned the high speed servos, giving me a strong preference over buying something else
