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.

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.

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.

My husband got this as a toy for himself and now the grandkids love to play with it.

Came in missing screws base was not attached to arm. While fixing it one of the screws stripped. Power cord is really short and couldn't reach now I need an electrician to add outlets for a dedicated circuit.

This arm is beautiful, robust, and pretty amazing at this price point! It has a very smooth movements. Easily controllable via several different methods including a direct web interface via IP address as soon as you power it up. It is also expandable with sensors, cameras, and more SBuss servos. Although I did read that you will want to purchase waveshare servos to avoid any complications with compatibility however, I don't see this as an issue because their servos are strong and reasonably priced. Overall I am quite impressed with the WaveShare M2 arm!

I haven't had a lot of time to play with it yet, but this is a fun project, documentation is available at the manufacturer's website, and basic controls can be used through a web browser via ip address.
