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.

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!

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.

I have seen some great quadruped robots on this site in the past few years and always wanted to build one myself. It became one of the most time-consuming projects … Read more
