My idea for this project came from the video below. After watching it I had to build my own version.

My version does not work nearly so well. Being strapped for cash at the moment I decided to see what I could build with odds and ends around the house and parts left over from other projects. This was really fun to make and I hope to improve on it later.

Modifiy your servos using this instructable as a guide. I left the original wiring intact however and used my soldering iron to melt two holes for my wires to come out. I did not modify anything else on these servos.

I wanted to use an old OOpic microcontroller to set up my servos, but I no longer have a compiler for it and cannot find one.
Great job. I love the way you made your gripper. Very innovative and creative. Keep up the great work.

Did you see my project?
To make it mobile or just consume less power, I worked out using a horse syringe as the vacuum source.
Nice job connecting this to a robot arm!

That's awesome! There's at least one other I'ble on making the suction gripper -- you might see if their method could be adapted to your project.

Thanks, I had not seen that other project.
