How to make a medium size robot. Let's make a guide!

Now we have wonderful tutorials for making beginners and small robots, but bigger robot need stronger frame, motors, bigger batteries and can do much more work.

There are good examples of medium size robots here, but it would be useful to me and maybe others if there is a good comparison of various motors and drivers, how to get them and what to care about to avoid crashes and dangers.

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!

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.

Quality of Life

I'm on a crusade. A crusade for better quality of life. In fact, a crusade for quality that means life. A lot of money is wasted. People are being injured, sometimes seriously, or even being killed because of poor quality software. We have the power to help put an end to it. If you have read any of my previous posts, you may have noticed a recurring theme: software quality. Even if the post wasn't about that at all, it seemed to always crop up. And that is what my crusade is about. I need your help.
