Hi all,
I'm a lurker/newbie. I'm wanting to build a controlled platform that can move
and rotate (sort of like a turtle using LOGO). I'd like this platform to carry
my E-10 camera (weighs 37 oz./1048 grams). Can anything using the RCX/mindstorms
system move this much weight?
The purpose is to build a rudimentary motion-control system for doing stop
motion animation pans/trucks. Ideally I'd program in the camera movement and
then have the robot execute the steps one at a time (basically send a "do next
operation" movement). But before I get into all that I figured I should find out
of the legos have the power needed to move the mass.
Any advice tips etc are greatly appreciated.
Thanks in advance,
g

| To add some further information, I popped the unit open last night and observed that, as I had hoped, mechanically the unit should be capable of operating correctly. Each motor channel has a mouse style slotted wheel and sensor, so the firmware (...) (21 years ago, 12-Nov-03, to lugnet.robotics)
