Review: Easily the best arm for the price point - I ordered one of these arms to use on a humanoid robot I’m building. Upon unboxing, it was up and ready to use via the Wi-Fi interface in under 2 minutes. It’s a good size with solid human comparable reach and just in a quick test it could pick up a game controller (by the wire) at full extension with no problem. The mount holding the LED also offers possibilities for adding cameras to the end effectors which is a bonus. This is easily the best robotic arm I’ve seen at this price point. Highly recommend. Just be aware the documentation is on waveshares website as there are no instructions in the box.
Review: Nice robot arm for the price, good hobby starter - I bought this just for a hobby. Luckily it comes pre-assembled so I just had to mount it to one of my tables. For what it does, I really like it. The web based control is simple and to the point for just moving the arm around. I did manage to hook it to my computer using Ubuntu. It is a pretty good learning curve to lean all the things this arm can do, but for now I do look forward to it. Eventually I plan on mounting the arm to one of the UGV bases.

### ⭐ What a pain!!
*by S***N on November 22, 2025*

This thing was a pain to program. Even with AI help, it just kept erroring out. Instructions were hard to understand. Not much in examples on the web. Sent it back. Too bad, it is quality hardware, but the translation and clarity on documentation ruined it.
