Great job.  It's a very amazing walking bot.  This shows that the Arduino can do just about anything with the right parts and code.  smiley

If you plan on extending your robot to more servos but realizes that the Arduino can't handle that many, i recommend you getting Lynxmotions servo controller. You can connect up to 32 servos to it, and it is not pricy either, it costs about as much as an Arduino board does. You control it via serial commands, so you can receive more processing power on your Arduino board as the servo controller does all the processing of servos.

This is a really neat project!

I am planning on taking on a similar project using eight servos, and I have been searching for methods of powering it. I noticed in your pictures and videos that you used a computer ATX power supply that was able to successfully power more than the amount of servos that I need. Could you give me the specifications of that power supply (mainly the wattage), how you modified it, how you wired the servos up (parallel circuit, I assume?), and maybe where to get one? Much appreciated!

Hi, you coneccted the robot to external power because yours servos need more intensity, true? I'm working in hexapod but the servos are crazy and i'thnik is the 1000mA no are enough.
