Hexapod queries

Hi everyone,

I have been thinking of building a remote controlled hexapod from scratch including the code. However having never built anything like it and having basically no experience with arduino, I have a number of querys I would like your opinions on.

An Endless Journey

Robot Costume Contest

Hey guys!

If anyone is interested (and has mad costume-making skills), ezrobot is running a costume competition for Halloween! It can be any robot, it does not have to be an ezrobot. :) You can win some credit, and we would love to see some submissions from Let's Make Robots!

Hex Caster

Hex Caster is my attempt to come up with some play on the word "hex".

I plan to use this PCB with both my hexapod projects.

Here's the top of the board.

Below is the bottom.

The servo banks are broken into groups of six.
