I2C Thoughts...

...from the newbie... Can each digital port send I2C? Because I saw some I2C servo controllers that handle multiple servos. Could this expand the number of servos (or H-bridges) controlled?

Whoa, if you're willing to do that! Hats off to you:) It will take some real cool engineering to mount the pot and motor shaft, etc. But when you get it going, I bet it will be awesome.

I'm constantly impressed of the engineering that you guys are all doing. I know I "hack" things together pretty quickly. But nothing I do is very complicated (except maybe making the ez-b haha). My mechanics are hot glue gun and screws and a dremel.

Hats off to your confidence!

I think its better than Aibo because its large enough to add other stuff in. Id love to have Aibo but is running $800 minimum right now. its gonna be a fun project. Reading up on MS RDS now

I know, "holy dig up old thread, Batman!"

I was just wondering if DJ, Troy or anyone else has tackled this project?

Do you think that the V4 would offer better possibilities?

I am seriously thinking about tackling this project. I would replace all of these leg and neck motors with servos. It could get pretty costly. Programming this guy could be "fun".

OH GEEZ! 2011?! I had more drive back then. I did give up on that one because even if I took apart some servos for the boards and used the potentiometers in the joints that are already there I would still run into space issues. There doesnt seem to be enough room for the EZB and extra boards. If you think about the cost of servos and an ez-b you might as well purchase an older Aibo. If cost is no object, why not build your own 4 legged bot so you are guaranteed to have room for all the gear you want.

I found the models to 3d print the i-cybie. It would allow me to provide more room I think. The cost of the servos is going to be pretty high. I count 16 of them. Then there are 5 ir emitters, 2 buttons, a camera, photo sensor and an ir receiver. Add in a tilt sensor, sonar, 2 LEDs and compass... I don't think there are enough ports on the V4.

idk, I will probably buy one for the body and start chopping it up to see if its even possible.

Thanks for replying. I may be taking on more than I can chew, but heck...thats how I learn best.

@Troy- Man, I just saw a brown one of these guys at a rummage sale yesterday for $2. I put it down out of ignorance, I even said screw it and was gonna buy it for parts but someone snagged it as I was on my way to get it. It didn't have any of the connectors or cords or anything. It had that chip that went into the side though. I would even give it to you now if I did just because you'll do more with it than I could. I'm super sad I missed out on this.

Ah, darn. I'm trying to find one now. Saving on initial cost would be great. There are some on eBay for about $50. I would love to start on this one. Would be interested in seeing what size servos I can fit into this guy.

@antron007 thanks but at one time I acquired a total of five at very good ebay prices. Two of which were in perfect order. After seeing those Aibo on youtube I was very disappointed in i-Cybie. lol
