Thanks! You are right! They are squeaky. Actually this is my first experience with a legged robot and I just wanted to play with a lot of servos to generate different gaits. So I bought the cheapest micro-servos. But for the future projects like this, I would purchase stronger and better servos.

Hi Rasoul

I like your robot, and the way it walk

I built mine with standards servos but I think that 4Kg.cm is a minimum torque for quadruped (depending of the structure).

If you are interesting I posted videos in those we can see the consume under 6 volts

Have fun with your quadruped it’s a very fun experience !

Hi MoX, Thank for your comment!

I saw your quadruped robot’s videos. I think your work is so cool! Your robot has 3DOF per each leg which lets you generate more complicated gaits than mine which has only 2DOF.

The servos I used are not strong enough but I think for the first experience they were good choice. Another problem that I am facing is to manage driving 8 servos by Atmega8. I use a timer interrupted based algorithm to control servos according to the desired gait and at the same time in the main loop of the program I would like to add more features like obstacle avoidance and so forth.

… And as you mentioned, it is really FUN!

Thanks! After it took its first steps, it seemed to me that I could add some shell to make it like an animal!

Hi Rasoul

the evolution of my robot , will be to use some sensor too

I think that I’m going to use an ultrasound sensor for the beginning, and as my quadruped walk slowly, the time for the reading of the sensor, the program processing , and a communication with a UART between a SSC32 servo’s control (from Lynxmotion 40€) and a Uadruino Uno; could be faster enough to be reactive… i hope

Have fun with your robot !

I love your little bot. I also did one with cheap servos and it runs well with it…ok, one servo is broken now but that’s acceptable when I see how he was treated during his presentations

I like yours, too!

I like your little quadpod built with the same number of micro servos, too. Unfortunately I couldn’t spend much time and effort to make it as perfect as I planned for at the beginning.

I will follow your little quadpod upgrades

Yep, the same here. I still

Yep, the same here. I still want to improve the walking, put more sensors on him, program more different behavior but the time to do that all is just not enough. Now I have to replace one servo because Chopstick Junior will go to the next photo shooting next Saturday
