Hi guys, I've been reading through the old posts on this news group for a while (standard netiquette, dontchaknow), trying to get a feel for the group. I'm about to start the "hard" part of my own robot project (the bit that comes after dreaming it up), and thought I might describe it and see if anyone has any ideas on it.
Basically, the idea is to build a small robot that can do simple gardening tasks such as weeding, and small digging projects. The system at the moment can be called a "brick", as it does not move and has no sensors. It's a mini-itx board (ME6000) in a 20cm^2 wooden box (with a little bit of air circulation to help reduce its spontaneous-combustibility). I have the system currently wired up to a standard computer PSU, which means it's pretty-much confined to the desk.
The next step is to get it off the desktop. This involves figuring out a way of powering it. I have a DC-DC converter (mini-box.com's PW-200-M), so I figure I can just attach a 12V supply to that. I'll be trying with
8 AA 1.5V batteries later on, to see if I can get it to at least boot and run for a minute or two. I suspect it will need a larger reservoir, though, for anything longer than that ;) Then, I'll be working on attaching and controlling motors so I can move it around. I figure there are enough articles on controlling motors through the parallel port out there for that to be the place to start (I am a total virgin where robotics are concerned), although I'm happy to be corrected.Anyway... that's the plan!
