Robotic Claw Tutorial


We've received a lot of questions about using our robotic claw with our medium servo. After trying to answer the questions over the phone, John Trepke (SparkFun Tech Support Specialist) created a tutorial to show you just how to use this dynamic duo. The video below will show you the claw in action, but read the tutorial to see how you can do the same.

This tutorial will guide you through mounting and assembling the servo/claw, as well as how to use basic Arduino code to make the claw open and shut. Once you've got these basics down, you'll have the knowledge to incorporate the claw and servo into your next robotics project. Enjoy!

  • Now to take the mini-bot class and marry the claw to the robot. I can have it autonomously pinch people!

    • LOL That’s pretty much what I did with mine when I got it. RC, not autonomous, but my wheeled bot had one arm for grabbing, and the other for punching its now-restrained victim.

      • With a name like your’s wouldn’t a quadcopter be more appropriate, a Hunter/Pincher as it were?

        • Or, make a quadcopter that flies around and picks things up (;

        • I wouldn’t want to get pinched by a quad copter. I’d worry I’d get a buzz cut while it was trying to pinch me.

          • I guess it depends on how the quadcopter is designed. For example, that wouldn’t be a major concern with a telescoping arm that extended several inches from the outer diameter of the rotor blades, or similarly a smaller extendable arm pointed downward.

  • This is fantastic. I’m going to build a crane-claw for my kids bedroom. The servocity servo pan/tilt(for more weight), some aluminum angle, heavy fishing line and your joystick break-out - and I’m in!

    Now when I say - “clean your room!” It’ll be fun!

    Nice work guys - especially on the price!

  • Would be funny to see this made into a small Arduino based ‘Crane Game’ / ‘Drinking Game’.
