Rotating and Lifting Head Video
Wednesday, 05 September 2007
I got around to making a video of my 914 rotating and lifting head mod which you can see below.

You'll notice that the lifting motion is quite slow - if you look closely you can still see the motor shaft coupling rotating right up until the blue under-head lights start flashing. The lifting speed could be improved with a geared DC motor and some end switches, but the main limiting factor here was stepper motor torque vs step speed.

All in all it serves the purpose for housing extra sensors such as sonar and my IP web cam - the head wouldn't have to lift very far in order for those to look out. The total lifting height is around 5"/12cm.
