Hello everyone,
I want to share with you that I started working on a walking robot based on what I have learned from this website; I started by molding the body and legs using Houdini 3D software. I ended up printing the parts and mount the parts; my dream is to let Arduino and Raspberry Pi communicate together in the future.
Here are some pictures of the project. I hope you like it.

Looks pretty good so far.

@will Thanks; I am facing some issues with the servos; I feel they are not strong enough, but I think that is because I still did not run it on Litio batteries which should have a higher AMP comparing with the USB port from my laptop.

Yikes ! You're running that whole machine from your laptop's USB !! I'm surprised your laptop hasn't barfed up a lung already 🙂
The servos do look smaller than I expected, how much does the whole assembly weigh ?
By the way, your 3D prints look great. Are you using brass inserts or embedded nuts to hold the parts together ? In the photo they appear to have a very nice finish, nice corners and edges and a minimum of exposed bolts. Very nice.

Yes, I am doing everything from the USB right now; I don't have much information about the servos and ideal power. I have 12 servos, and yes, I think they are small. Servo vendors mention that they are good and powerful, but I might have overweight or less power.
The total weight is less than 3 pounds.
For the 3D print, I spent a lot of time modeling, and I started from the size of the servos, then I attached everything to them.
Regarding your question about the nuts, I have normal nuts, but in the 3D print, I kept holes to hold them inside precisely.

Well, you've done a very nice job of it.

Nice job, I like it.
I built (from a kit) a Hexapod that used a 16 channel PWM/Servo driver. Is that what I see installed next to the Arduino?
Your project looks like fun. You're going to have to program some dance steps!

@thrandell Yes, you are right. I have two 16 Channels PWM/Servo drivers, one on the top and the other under the body; I will use the upper one for the ultra sound navigation with small servos.
I am happy that you like it and yes soon I will show you some dance.

Awesome walker!
All your work has paid off. It looks like it's walking on tip toe...
Each leg has three motors, what will the the topmost motors do? A side to side shuffle?
Are you planning to control it remotely or will you add sensors and turn it loose on the world?

@thrandell, I am happy that you liked it; the topmost motors will do the side-to-side shuffle. I plan to control it by voice, and the sensors will do the rest to navigate without accidents. The cool thing is that this robot has mounts for future upgrades that allow it to fly.

I think that will be the first Drone-Bot to grace the pages of this forum.

Did you see this drone-bot out of Caltech?
