This is a simple robotic end effector modeled after the Aluminum Sparkfun Robot Claw. The effector uses a parallogram design so the effector grips stay parallel at all times. The design has an impressive opening range. I have included the Inventor file so you can make changes; just show one “body” at a time and export so you get individual STL files.
I just needed something simple to hold and drop things on command. If you wanted to use this to pickup objects, then the effector tip (Clamp) should be made thicker or at least into a cross; I just dipped mine in rubber cement and that was good enough.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
Have an amazing project to share? Join the SHOW-AND-TELL every Wednesday night at 7:30pm ET on Google+ Hangouts.
