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.
Dude - B9 is my idol. I have a 2 ft version I am modding next after I finish my omnibot. Then on to the big one with the wheelchair drive (scratch built). There are several builders on here that are working with the larger stuff right now and should be able to help. Welcome!!!!
Thank you for the response bret.tallent. Mine too will be completely scratch built. I am making it with my brother. We have not gotten too far in the building, but we have spent years researching, collecting parts, and planning. We intend to make it fully articulated - arms, claws, etc. If you are looking for any ideas I have thought much of it through already.

Will the sabertooth motor driver power the wheelchair motors? I think it should - and provide speed control
Oh and PS, welcome to EZ-Robot Danger!
Thank you DJ Sures
I have to confess that I was thinking of cheating (I like to think of it as a creative work around) on the wheelchair motors. Since they run on 24V and everything else runs on 12V, and because the wheelchair has speed control, a built in charger, and a regenerative braking system already in place. I might leave the entire wheelchair harness intact, and electrically separate from the rest of the robot. I have thought about mounting the joystick inside and moving it with small actuators, or servos. I tried bypassing the joystick electronically, but the system is very sensitive and trips into shutdown if it does not get the proper voltage from the joystick. This might all sound crazy, but as I said, I am new to this, and open to suggestions. It just seems sensible to me to utilize the motor controller that is already in the wheel chair.
I still have the other motors, arms, torso rotation, etc to contend with.
I too was planning on just using the joystick and controller that came with the wheelchair motors, and using HD servos to move it.
Hope you got some serious cash to blow lol
I wish!!
I do not have the budget that some who build these things have. That is why I am building my own body parts and trying to save money by using surplus wiper motors and $2.00 relays instead of large servos. I know that it will have its limitations, but I would like to make it as intelligent and functional as possible. This system seems to be far less expensive, and easier to use as anything that I have found. I am hoping that it will adapt to what I am trying to do. The motors and parts are big, but the relays will be doing the bulwark. What I need the help with is linking the hardware to the relays.
@Danger! - check these out. http://www.ebay.com/itm/320813643959?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 you can get them in much higher voltages and I believe you can plug them right into the EZ-B. This is what I am planning on using 9or something similar). You can find them all over ebay for pretty cheap.
