Dexarm

The DexArm New Luxury Edition All-In-One Robotic Arm is a 4-axis desktop robot arm with a modular design and 0.05 mm high repeatability. It can be easily turned into a desktop plotter, laser engraver, and 3D printer.

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

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

DexArm do not like handling screws and cables when using an intelligent product. That’s why they creatively pack every function into a module to remove the unwanted screws on the end effector. Switch out modules in just one click.

DexArm gives you an intuitive and interactive way to control and bring your ideas in just a few clicks with the software. To keep DexArm easy to use, they integrated Blockly into the software, which allows dragging and placing the code blocks to control Terkobot.

Control a robot arm is as easy as play a board game. Also, an API is provided for experienced developers to control DexArm in Processing, Python, and G-code.

To make controlling DexArm even easier, they designed the 3.5-inch touchscreen to allow you to check the status and command DexArm 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. With the pen holder module, DexArm can write a beautiful hand-writing letter and draw an artistic picture, Bring art to your home or write your homework.

Core Highlights

Universal Robot Arm Kit on Your Desk

The DexArm desktop multifunctional 4-axis robotic arm integrates writing, drawing, laser engraving, 3D printing, pick-and-place handling, programming education, and automation demonstrations into one compact platform. Its desktop design makes it suitable for classrooms, laboratories, studios, exhibition booths, and small-scale automation applications.

Multi-Function in One Platform

By switching different end-effectors, the DexArm robotic arm can work as a drawing robot, laser engraving device, 3D printing platform, or light-duty handling system. Users can choose pen holder, suction cup, soft gripper, laser module, or 3D printing module according to project requirements.

0.05 mm Repeatability

The DexArm robotic arm supports up to 0.05 mm repeatability, making it suitable for trajectory drawing, repetitive handling, educational experiments, and light automation demonstrations. The reference materials also list 0.05 mm repeatability as one of the key performance parameters.

Modular Quick-Change Design

The modular end-effector structure allows users to switch functional modules quickly while reducing complex installation steps. This improves usability and expandability for education, R&D testing, maker projects, and multi-scenario demonstrations.

Easy Teaching and Programming

DexArm supports manual teaching, graphical programming, API control, and ROS development. Users can record motion paths through hand-guided teaching or control robotic movements through programming, making it suitable for both basic education and advanced development.

Quiet and Compact for Indoor Use

The compact structure allows the robot to be placed on desks, lab benches, or display counters. The specification sheet lists a noise level of around 40 dB, making it suitable for classrooms, offices, laboratories, and exhibition spaces.
