In the list of components he mentioned RST, GND/BLK Prog., A5 A4 A3 A2 A1 A0 AR,J, 7805 and I am not able to understsand the names of components, I have tried to contact him but he doesn't reply back and also I want to know what diodes he has used, so that his servos do not heat up.

Servomotor torque requirement for a quadruped robot

Hello,

I'm planning to build a quadruped robot soon. My design is very similar to the design in the following link.

http://letsmakerobots.com/node/28077

I'm not that good at mechanics. I like to calulate the torque required for each motor. Is it ok to use the formulas/procedure in the following link to design a quadruped shown in the above link?

Hello,

I have started building a quadruped robot using Lynxmotion SES parts. I have the Lynxmotion quadruped body kit and 4 SES 3DOF legs. I have bought servos and put everything together. However, I'm much more comfortable with the code than with the mechanics.

Robots With Legs; How to Walk or Run

Does your robot walk like this? http://www.youtube.com/watch?v=WTHI8o5ZOFk&feature=related Notice the heavy jarring to the machine and to the inhabitants inside. This jarring is not good for the machine, especially at the joints and may eventually break  something.

Yet another walking robot but starting from scratch.

Amazing homebuilt quadruped

Searching for robot videos on youtube I came across this japanese guys profile. The quadruped in the video has a really interesting leg structure, not to mention the extra drive wheels. Check out the videos, it just looks and moves amazing!
