Excellent robot arm and impressive customer support
I had some issues with the robot arm when I received it. However, customer support was excellent, to be honest one of the best that I ever had. This is a very good option for a budget robot arm.

What would you expect for the robot which costs around 250€ ? A toy? Ordering that I was totally impressed how well the robot was developed. There's even a place for customizations - for example I have added 2 more axis - Claw tilt, rotation and the claw itself. Had problems at the start that the EOT servo was not working, but resolved that through the customer support - ordered another one and they refunded me costs of that servo. In addition, I have learned the hard way that the USB controller is just for programming and not for servos - I have burned it. Now I know that to control the arm it's better to use external power. But even with that it works perfect. I've added OTA Updates to the firmware, couple of new JSON commands to control the claw and plan to use it in my project. If I would have more money and the v.1 of the arm would have the same controller, I would buy the first version - it looks much more reliable. But still, this one is pretty decent. Already using it like one month.

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.

Planning to control it via metal with a jetson origin 8GB and attach stereoscopic camera module to build an unbeatable opponent for my game of chess I leave on my table now. feel free to message me if you have experience with this Robo arm or working with Nvidia Cuda framework. My next project will involve much larger scale prototype of a two arm robot that can do my dishes and why not give it a dog body to walk around with. The dog body doesn’t work it’s going to be repurposed to chase my cats. I’m loving the products waveshare is coming out with
