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)

I like the gripper once I got it together but it does take some time to figure it put. Better instructions would help

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

The installation instructions are terrible to say the least. I am reasonable handy but it took me about 8 hours get it installed.

The kit is....ok. The stampings are good. No burs or sharp edges. Some of the holes had to be redrilled they didn't line up and everywhere flathead screw were used need to be countersunk. Fail enough. But the instructions....the instructions are bad. They are tiny, poorly printed, even more poorly translated and just plain confusing and/or wrong. The pictures on the Amazon page are more useful to help understand how it goes together.

First of all the manual is basically illegible. It's just a series of thumbnail black and white photos printed on someone's home printer. Most of the text is Chinese. I managed to find a pdf online which helped because at least I could see the photos then, but these instructions were not great. Secondly, I spent almost two days trying to understand why it wasn't working or responding to anything before testing my Arduino on a different servo and coming to the conclusion that the servo included with the claw is dead. So. Thanks I guess.
