Swaytail Professional Metal Robot Arm/Gripper/Mechanical Claw/Clamp/Clip with High Torque Servo, RC Robotic Part Educational DIY for Arduino/Raspberry Pie, Science STEAM Maker Platform (Silver)

A little time consuming to assemble and very sharp, but it saved our robotics season at the last minute!

This is a strong and steady. The claws are aligned. It takes time to install and it’s a good product.

This thing is hard to assemble. There are no instructions in the box, just a bag of parts and a little card with a QR code. So be aware that you need a phone to scan the code and access the instructions. The instructions themselves aren’t bad, but they aren’t great either. The end result is a nice claw that you can attach to a robot or something else, and control with an arduino or a raspberry pi. The claw does not have a strong grip, you would need to upgrade the servo to make it stronger.

I purchased these grippers as part of a project I am working on to equipment a drone (a pixhawk based coaxial octocopter) with a payload gripper. These grippers assembled nicely and function well. The servo included has a good grip strengh (enough to hold a filled water bottle easily) and the assembly was straight forward and largely self explanatory. My only recommendation to the vendor would be that the instructions were printed in low resolution black and white. given the price tag I would have appreciated a full color print

Its a decent product, but its a bit too costly for what it is, and the fasteners are constantly coming loose. Some blue locktite is advised
