Thank you bret.tallent

I have found many relay controllers that plug into the computer, but finding something that is compatible with this hardware was the issue. This is a big help. Now at least I know what direction to go in.

@Danger!,

Hi, I too have a wheel chair setup and I have to say unless you have your hand up someones you know what you are not going to get any info of the electronics for almost ALL electric wheel chairs.

I have a P&G controller system and as far as I have been able to get is a serial cable for programming and most important the manufacturer level software.

IT TOOK ALMOST A YEAR OF HUNTING AND RESEARCH TO GET THIS. The company really protects it proprietary goods.

That said, you can wait forever to find info or spend lots of money and alter the control system or do as your thinking and connect servo's directly to the joystick and start playing with your bot right away before , in my case die of old age.

Thanks Dave. I do have the spec sheet for the JC200 Joystick if that is any help to you. I am sure that someone with more skill than I have could create the proper voltage swings for each axis with a controller and substitute the joystick. As far as I am concerned though, I am not a professional. If I can get it together and working in some fashion, I will be satisfied. The wheelchair works fine right now. I do not need to recreate the electronics that I already have. I still have plenty of challenges ahead of me.

I love how you did your torso, it looks really good. Especially compared the expense of the others on the b-9 site. How are you planning on handling the bubble and the collar?

The torso has come a long way since those pictures. We have the arm sockets in and have been working on the Bondo. We had to put that on hold until the spring because we were doing the Bondo outside. 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.

I am just weighing my options here. Would this controller plug right into EZ-B? The more I think about it, it would make things a lot easier in the long run.

Signal will plug in and the ground to your power supply must also be grounded to servo ground pin. To be honest.there are cheaper motor controllers out there. Here is a 68amp http://www.ebay.com/itm/Double-BTS7970B-68A-high-power-motor-driver-module-servo-driver-module-/150750031974?pt=LH_DefaultDomain_0&hash=item231966f066

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
