This is a bit of a general question. I have a project I want to put together similar to the 'sentry gun' projects seen on youtube. I've gathered an SSC-32 servo controller and couple of small servos - i think they're around 76oz-in - and I made a little brace so they are attached at right angles. This basically works as a pan-n-tilt mechanism, and I've plugged the controller board into my serial port, and it all works nicely. The problem is that it's a bit too dainty.
I need way more muscle, and so my question is in several parts.
- Where is a good place to get hefty servos for a good price? I need something that can easily swing a 2x4 around (around 2')
- Can someone point me at a tutorial for hooking this up? I assume the SSC-32 board and it's 4 AAs won't cut it as I'll need more power for those bigger servos. So How do I control the servos with the board but power them separately?
- Would there be an advantage to using stepper motors instead? Like, more torque/$? I've never dealt with steppers, but I heard they were similar.
Thanks for any advice!
