Hi David and thanks for your input!
Let me say that everything is very interesting over here..
Here a couple of quick points in mind to go over after reading you.
I saw your video, that's a very smart design detail to move the sensors all the way to the front. Just bear in mind that I'm planning to build a "base" of about 30 inches long (my sketch is just that, a sketch). So now I know that I can pull the sensors and discretely install them as much as I can all the way to the front to gave my processor a better response time (thanks!).
Driving wheels. I have to say that all your observations are right! I was just trying to get that part out of the equation to focus on the steering system but here comes the interesting part of your comment. I understud the amazing power behind the 3pi. I've placed a post on the 3pi area asking about if it's possible to replace their motors and give it a try. Ben said basically that makes no sense (and here Iam re-thinking the whole story to get myself another option).
Now I'm having again some of those same questions.. Does baby orangutan support 12V and a few amps? I'm guessing not, that's the first reason to "remove" the driving system from the processing unit. Actually the whole thing is going to move not faster than a foot per second and the trace is not going to have those super tight turns.
The load over this base is going to be big, I'm talking about 80 pounds so, in the prototyping phase, the driving mechanism is coming out of 2 heavy duty battery operated drills (and looking for something more efficient ahead) in fact, the other option comes out of a 200W electric scooter motor and mechanical reduction (2 wheels on same axle driving forward). Or if a better idea why not 2 independent ones..
Going back to the point (I'm sorry) I need a good advice to resolve the logic and get signal to move my steering mechanism. Or even better if it's possible to "clone" a 3pi but at my scale...
In fact, am I wrong or baby orangutan just control motors..? and not servos.
Thank you for reading!
