I am looking to make a remote controlled camera for the baseball games we cover.
Goals: 1. Has to be able to move a standard camcorder, at a fairly decent speed to track a moving ball. 2. Has to have a fast response, it would do no good for an operator to turn the camera to follow a player or ball only to have it respond a second later. 3. Can't be a joystick interface, since sometimes looking a specific spot on the field requires the operator to move to that spot by memory. Doing this with a joystick would be cumbersome, and look mechanical on the video.
I looked on the net and found some people that were using a wiimote and some servoes to point a webcam. I was wondering if it would be better to emulate them and use a wiimote or something similar for the operator (could put the wiimote on a standard tripod mount to emulate the feel of a the camera), or would it be better to use encoder or even potentiometers?
I don't think I have any servos that would move that much weight around easily, I do have a bunch of NEMA 250oz in stepper motors, and a controller, plus I could use microstepping so I don't have to gear them down. Could I use this? Or would it be better to find a more powerful servo?
I have a cnc machine so cutting out the case and some of the parts should be pretty easy, though I know those are some famous last words.
