Summary

This is the forearm for my robot arm project.
http://youtu.be/JUvv04BSIvo

This is a first try, and work in progress. Don't expect a fully functional thing.

The metal gears have 20 and 40 teeth and a Modul 0.5.

This is a add on for my printable "Robot Arm"

Hi there,
Many thanks for your sharing.. I am now working on this too. Hope I can make one within few month.
BTW, I didn't see the file of the orange cap on the side of the robot. Do you release the file? or I have to draw one with my Solidworks?
Thanks again. Great work.

Hello,
What sort of Steppermotor did you use for the lowest Joint, that one which you couldnt move becaues of its own weight?

This is a great project that I am very interested. I would love to look at replacing the steppers with pneumatic rotary actuators and proportional valves to provide greater strength and introduce the idea of using the arm with an underwater ROV.

Great design. I love it.

Awesome. Definitely going to follow this, Many people want to get in to this type of robots but are afraid to make the first step. You are making it a lot easier, Keep up the great work!

very nice project
