Canonical robot record
Overview
The Dobot CR3 is a compact six-axis collaborative robot arm from Dobot Robotics (Shenzhen Yuejiang Technology), the current generation of which is marketed as the CR3A within the company's CRA collaborative-robot family. It is designed for light-duty handling and flexible automation, with a small footprint intended for quick deployment into tight spaces such as retail counters, beverage and coffee service, light industrial cells, and education and research labs.
The robot uses high-performance integrated joints and a redesigned control cabinet running Dobot's DobotStudio Pro software, which the company positions around improved cycle time, safety, stability, and scalability. A stand-alone safety controller and a suite of built-in safety functions allow it to work alongside people without heavy guarding.
Dobot offers the CR3 directly through its official U.S. online store, where it is listed as an in-stock, purchasable product, reflecting that it is an actively sold and shipping commercial cobot rather than a prototype or research-only unit.
