For quite a while now, I've been roaming your site, itching to get started with some decent robotics. I'm a big fan of your work.
I've come to the stage of actually ordering the bits, and would like some advice on this matter, if that's not too much to ask?
Welcome to the forum!
I'm looking at a tri-track base with PS2 wireless control, an arm mounted on top, and a pan/tilt mounted somewhere on thesame base rotate with some SES brackets for a wireless camera mount.
Not sure if that configuration would really fit. You might have to choose either the arm or the pan/tilt, not both. Not without modification, at least. The base rotate kind of
covers the spot where the pan/tilt assembly would otherwise go.
1. You offer several (maginificent) arms. What one would you recommend to be put onto the tracked chassis? Powerwise and sizerelated? I'll be using standard mounting method for the base rotate, and would like to be able to reach sideways over the tracks at least. I do not intend to pick up any cars or punch through walls with it, before you ask. <grin>
Same question for the wrist rotate.
Not sure what you mean by "powerwise and sizerelated", but as far as arms that can reach over the tracks, I would go with either the B or D arm, the D arm being the larger/stronger of the two. The A arm can barely reach over the tracks, but it might also work for you.
2. Batteries. As I understand it I'll need a 6V battery to power the servo's and logic (bot board 2), and a 12V battery for the track motors. They come in various sizes, so what ones would you recommend for said setup? With the botboard, PS2 receiver and sabertooth installed inside, what battery combination would/wouldn't fit inside? It is rather important everything will fit inside smoothly, and I couldn't find the internal sizes of the tracked chassis with electronics installed.
3. If all goes well, the next project will involve self-docking and charging. This'll be greatly easier if I only had one battery type and voltage to take care of, so do you have any suggestions for any 12Vdc to 6Vdc converter setups for this, or is running the whole thing on 12V battery voltage plus converter a bad idea?
If you're trying to just use one voltage of battery, it might be easier to use three 6v 2800mAh batteries instead of a 12v battery. With some clever wiring, you could charge them up as three 6v batteries, and use them as a 12v battery and a 6v battery, if that makes sense. I can draw up a diagram if that isn't clear.
4. Camera. To be added later, but I'd thought I'd throw it in- I'd like live feed coming from the robot, to be visible on the apple Iphone. I'm a bit unclear as to what options work the best. As I gather there's two distinct different systems used. One uses a camera with onboard WIFI, and transmits directly into your WIFI router and hence easy to pick up on computer or Iphone. The cameras do seem rather bulky though.
The other one uses smaller cameras that transmit over radiolink to a seperate transmitter. How would this one end up on my Iphone, and what option would be recommended?
This one's out of my knowledge. I'll leave it to someone who perhaps has an iPhone.
