Hello. I am new here. I am new to robotics as well.
I am building a large, heavy robot ("Lost In Space" replica). It will be driven by wheel chair motors. The rest of the movements will be made with automotive windshield wiper motors, or similar. They will all be wired to automotive Bosch relays wired for forward or reverse. Will this hardware hook up to relays? If so, what would I need to get started? I would like to incorporate sensors, perhaps feedback from the wiper motors parking switches, camera, etc.
This looks like a good starting point from what I can see. Any advice would be appreciated.

The collar we will be doing with the usual club method. The acrylic was not too expensive. Another option that some of the early scratch-builders had, was to space out three Plexiglas rings (top, bottom, and a larger center) then wrap clear plastic tubing around them in the correct pattern. I do not think that would save any money though.
As for the bubble, I will be making a fiberglass mold (still have some left). I am debating the idea of making a DIY rotational mold, and casting it in clear epoxy resin. If that does not work, I can drill many small holes in the mold and put it in a box to vac-u-form some lexan. This will take all of the guesswork out of getting it the right shape.
We also found a pretty good looking cheap alternative to the neon.
There is no way to build one of these things on real short money, but I am trying to save as much as I can by doing all of the labor myself. Besides, without knocking those who choose to build with club parts, both my brother and I feel that when it is done, we do not want to step back and look at a collection of other peoples parts.
Is there some way to exchange email addresses on this site in case you want to discuss more B9 specific subjects? I do not want to hijack the "EZ-Robot" Board with "Lost In Space Robot" discussion. I know that most here are building other sorts of projects.
Or lower amp one, I have one of these for Omnibot :). $ 28 10a -45a peak per channel http://www.ebay.com/itm/15A-DC-motor-Stepper-Motor-Driver-Controller-Strong-braking-exact-speed-control-/160738732872?pt=LH_DefaultDomain_0&hash=item256cc66b48
I use a wheechair base for my Robot controlled by two servos which simply move the joystick
Initially I took unit apart and attempted to make a direct connection but decided to keep it simple
1 The originall controll unit is probably one of the most advanced motor control units,why discard it ?
2 So simple to programme when connected to Ezb
very happy with results
I guess that it pays to shop around. I wanted to keep the regenerative braking function of the wheelchair, but now I see that some motor controllers have that feature too. The more that I think about hooking servos to the joystick, the more complicated it seems. Two servos (one for forward and back, one for left and right) is not really compatable with most H-bridge applications from what I can see.
I did not see your post until after I posted my last message. Any advice that you can give me on setting that up would be appreciated.
it may be difficult to see how it works but it involves no modifications except extend the shaft of the joystick itself
Both servos are placed 90 deg apart on the same level ,both are mounted on a small cabinet hinge as they move with the joystick movement.
Take a look if you need further info please let me know
Have great fun with Wheelchair base
Simply connect a two channell radio reciever to the two servos , add a 2 channel radio transmitter and you have one powerfull radio controlled Bot.
Zoooooom !!! Zooooom!!!
Im working on a project like yours , I got 2 scooter motors working with a sabertooth 2x225 and another motor working with a syren10 all by using a wireless xbox controller.
Pm me if ya need some help
And Bret, there's your chance*eek*. Go for it! Even if it is not all there, those are all of the hard parts to get. I am allready comiited to srcatch building mine now.
