Rotating and Lifting Head Video - 2007/09/06 06:53 This thread discusses the Content article: Rotating and Lifting Head Video

One thing I'm curious about with the stepper, is does it "lock" the head in place when you're moving? The reason I went with a servo for my head rotation is so that I can lock it to a given angle and keep it there... is the stepper free spinning, or can you keep the head oriented in one direction?

Re:Rotating and Lifting Head Video - 2007/09/06 16:19 Thanks guys, the next step is to mount a couple of sonars under there and use them for navigation by scanning them around as the head rotates.

Yes, I can lock the head in one location using stepper motor holding power. I've set this as another command bit on the serial commands that are sent to the rotating motor driver so it can bu turned on or off at will or set to be on or off when the requested motion has finished. This way it doesn't use power when it's not needed, but can be turned on when the Bot drives around.

At the very end of the video, on your 914 screen, there is what looks to be a martini - what does the caption say?
