Summary

I wanted to create a robotic arm using servos, so I printed some linkages and did up some code in Arduino and MATLAB to run the arm using the Joystick shield for Arduino.

Instructions

Things should be self explanatory:

Base is anchored and has a servo pointing upward. The Rotating Base holds a servo perpendicular to the lower one. The Middle Link connects the second servo to the third servo and the End Link is attached to the third servo.

I would be happy to explain rigging up the servo electronics and sharing the arduino code, just send me a message.

what servos do i use

Standard hobby servos:
https://www.adafruit.com/products/155

The design can be applied to different servo sizes by changing the CAD but this particular model was made for the above servos.

Good luck!

I printed this, and everything works/fits well with the exception of the rotating platform. It doesn't seem to render correctly, even when run through netfab. Any ideas?

I just uploaded a new version of the rotating platform, I was able to put it in Makerware and slice it successfully. Let me know if this works.
