Mechanics and Construction / Light weight one axis hinge recommendation

« Last post by oldmicah on February 16, 2023, 07:51:13 PM »

I'm attempting to build a crow that can stay upright even when its perch tilts. For that I need to have some single axis hinges (not u-joints). I'm using 3mm rod for my internal supports and am hoping to find some light weight hinges that are sized appropriately and can take a lot of duty cycles and still remain fairly friction free.

I'm using the hinges on opposing platforms connecting by the 3mm rod to keep them separate. There will a mechanism that keeps the top platform (that will hold the head) parallel to the bottom platform that the feet are attached to.

1) I've included an image (tube with a fork on one side and a tabbed tube on the other with a pin tying them together) of one I'm thinking of but I can't for the life of me find the name of it. Does anyone knew the name so I can find one on amazon or McMaster Carr? (I could make this myself, but time is short and I have plenty of others things to do first)

2) Is there a better choice?

really appreciate the help!

https://www.yotamarker.com/t199-this-is-the-living-grimore

the livingrimoire is an AGI software design pattern.
it works like in the matrix learning scene. 1 line of code to add a skill

well it does a lot more than that, but that is the gist of it.

at the time of this post the livingrimoire is translated to the programming languages:
python, java, kotlin and swift

Hello, I wanted to introduce you to this robot that was a hit at CES.

An innovative system for moving it on a ball that allows it to be easily moved by hand without having to lift it.

How do I make the quadruped move? With servo-motor or piston? I really need help!

Mechanics and Construction / quadruped robot like Spot mini

« Last post by Bi1cool on December 02, 2022, 05:03:55 PM »

hello, i want to build a little robot as a prototype for a bigger one (the size of the real Spot mini). I was wondering how can i make the leg moving. I know spot use a piston system form the knee. Does it realisable on a small robot (like 50cm long and 20 cm height)? PS: sorry for the mistake, I'm french.

Mechanics and Construction / Suggestions on how to build a mobile robot that has a retractable arm

« Last post by Katrina8559 on October 19, 2022, 02:59:58 PM »

I am a relatively new robot builder and I would love some advice on how to bring this creation to life. I am interested in making a mobile robot that has a retractable arm that can be controlled easily. I am able to code in javascript, python, and c+++ so any programming tips are welcome.

Thanks in advance!

So I wanted to design a robot with ring picking and tossing mechanism on it, dimensions are 500x500x500mm. Tossing should be done using spring or rubber band, can anyone help me out please!
