Biped robot from scratch

Let's Make Robots Projects Showcase

Hello!
New to this forum and new to robotics.

Im about to build a biped robot, where i design all the servoerectors myself and
construct them in thin metal (sheet metal?) Sorry, english is not my primary language :slight_smile:

Any special things that I should think of?

Hope to learn alot from reading this forum.

Welcome aboard!! Be sure to show some pictures of your progress. And if you want to know what you’ll need, patience and alot of time. :slight_smile:

hm, sheet metal whould be a good start, but dont get anything thats too thin or it wont have enought strength

also, how big are you planning on making this biped, how many DOF?

finally, dont over estimate what servos u’ll need, most bipeds use 5645s and that is cutting it close

anyway, good luck :smiley:

Glad to see your getting into robotics. I hope you have good luck with your biped. A biped is a big challenge so you may want to start with a small carpet rover. You would probably want to use aluminium because of it’s strength to weight ratio.

Actually, if one wants to start out with bipeds, one of the best ways to do that is build a B.R.A.T. :smiley: This is about the smallest workable biped you can build, except for the BRAT Jr.

Sorry, I ment to learn simple servo and sensor control.

Thanks guys.
Not sure how I count the DOF’s… :blush:

I’m planning on using 6 servos, three per leg. Ankle, knee and hip.
Small IR-guided, collision detecting, light guided wheeled robots have I already successfully built.
Therefore I want to escalate to the biped…

Thanks again!

Normally, 1DOF = 1 Servo. :smiley: So, your biped leg would be 3DOF since it will have 3 servos.

And assuming your “BiPed” has only 2 legs, that’s 6 DOF… :slight_smile:

yep :laughing:

Scratch building is always challenging. I would not recomend a scratch build project as your first project. But If you feel you can do it then go for it.
