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 (Black)

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

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 this and couldn't assemble it due to a lack of 8 of M3 thin washers and 12 of M3 10mm male female standoffs. I exchanged it with Amazon, but the second one was the same.I put it together using parts I had and added a M3 lock washer on top of the bearing below the nut to keep the jaw from falling off after use.I contacted the seller and he was very helpful and offered to refund my purchase, but was unable to for some Amazon reason. Instead he sent me a tank car chassis that was very good and easy to assemble.

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

The item arrived poorly packaged with half the spacers missing and no instructions.

The media could not be loaded. Love these claws... perfect for DIY projects.
