In the past few years, we have covered plenty of amazing robot arms here. The Dexarm Maker Robot is also worth a look. It is a modular robot arm with an open source API and Scratch programming that can 3D print, laser engrave, and draw. It has easily changeable modules. It also has a 3.5″ touchscreen display that lets you check the status of your commands.
This robot arm has a 0.05mm repeatability. It doesn’t make a whole lot of noise either.
