Hexapod

Hye, Sorry to bother you, I have some questions about a hexapod. I want to make the same like this http://webx.dk/robot-crawler/robot-crawler.htm  for my college project, if you have time to have a look on it, I want to know the configuration of the pcb board, an electrical schematics electric parts needed, what cpu usses, what kind of servos (can I use weaker servos?) . If you can help me, I would be very pleased, if can't..no problem. Have a good day.

Hey guys.

I just got home from the rat shack with a few of these babies.

Nobody in my town has breadboards, so these have to do until I get one from the net. Anyway, I'm pretty sure I get the idea of how to use one, but I'm hoping to find a short tutorial on the basics of using it. I know they're cheap, so I can screw one up and it's a non-issue, but I'd like to avoid that if possible :)

Wanted: Sharp GP2D12's

I am looking for someone willing to trade. I need 3 Sharp IR GP2D12 sensors with the cables and I have:

Clean navigation using IR sensor

Anyone willing to give me a hand with this code please feel free to jump right in.

I have spent any hours trying to get this to work. I sure have gotten closer but the bot seems to get stuck n reverse for whatever reason. He will stay in reverse untill i bring my hand close to the sensor and then move it away very quickly.

He then continues forward. Sometimes it seems like he wants to turn toward the object he sees

Picaxe 28x1 with sharp GP2D12

I have made many changes to Fritsl's code, Some changes I understood and others I did not.

Frits F*cked up!

Did anyone else notice this? Start here... Anyone?

Frits, if there is one thing that pic chips don't like, it is static! You know those silly wrist straps? So why, why in the world, would you take pictures of all your parts for the start here bot on top of styrofoam?!?!?!?

I personally can not think of a more static-friendly item then styrofoam. Why are you leading our LMR kids on the wrong path?

SHAME! SHAME!

Note, this description is vague, but I'm trying to describe what I'm asking the best I can.
