Introducing Rotrics

Rotrics is the first versatile desktop robot arm with extreme 0.05mm high repeatability. Designed for makers, designers and anyone who wants to make meaningful things on their desktop! Easily do laser engraving and cutting, 3D printing and much more!

Build for makers and designers to bring their ideas to life, Rotrics’s functional modular design is aimed to complete any task from simply grasping, drawing to 3D printing and laser engraving.

Order now and get it in November.

Three months after our Kickstarter campaign ends and with the support from our backers, mass production has started and the injection molds are finished. So, get your Rotrics now and you can receive it in November.

The decelerator is the core of a robotic arm, our patented decelerator design reduces the gap between gears, allowing 0.05mm extremely high repeatability. Empower the capacity for high precision laser engraving, 3d printing even lightweight industrial applications.

We hate handling screws and cables when using an intelligent product. That’s why we creatively pack every function into a module to remove the unwanted screws on the end effector. Switch out modules in just one click!

Rotrics gives you an intuitive and interactive way to control and bring your ideas in just a few clicks with our software.

To keep Rotrics easy-to-use, we integrated Blockly into our software, which allows dragging and placing the code blocks to control Rotrics. Control a robot arm is as easy as play a board game.

We also provide an API for experienced developers to control Rotrics in Processing, Python, and G-code.  

To make controlling Rotrics even easier, we designed the 3.5-inch touchscreen allows you to check the status and command Rotrics within your hand.  Download the G-code files to the SD card and start drawing/engraving/printing. No need to keep connecting to your computer.

Rotrics can be easily transformed into a laser engraver with the laser engraving module. It is capable of engraving on wood, leather, paper, and other materials. You can make a meaningful gift for your friends within a few minutes.

New 3D Printing Module


With Rotrics ‘s high precision, you can print a 3D object with the 3D printing module. The build volume of Rotrics is bigger than 220x220x250mm so you can print some big model at once.
