DOBOT CRA Series Collaborative Robots
The CRA Series combines speed, precision and a broad choice of payloads and reaches in one industrial robot platform built for dependable, repeatable automation.
One Platform.
Multiple Configurations.
From compact 3 kg handling to 30 kg heavy-duty automation, the CRA range offers working reaches from 620 to 1,800 mm across standard, long-reach and high-payload models.
Every model shares a consistent control and software architecture, making it easier to standardise programming, integration and support as automation expands across your production floor.
Faster Cycles. Safer Operation.
Reliable Positioning.
Faster Motion. Shorter Cycles.
CRA’s latest integrated joints reach speeds of up to 223°/s, while EtherCAT communication delivers rapid response and smooth, stable movement. In material-handling applications, this can improve production efficiency by up to 25%, completing more work in every shift.
Built for Safer Collaboration
CRA combines a stand-alone PL d, Category 3-rated safety controller with more than 20 integrated safety functions and certification to ISO 13849-1, ISO 10218-1 and ISO/TS 15066. This provides the foundation for compact collaborative cells, with guarding, speeds and operating limits defined by the completed-system risk assessment.
Programmed Positions You Can Trust
Every CRA robot is individually laser-calibrated to achieve absolute positioning accuracy below 0.4 mm. Programmed points correspond more closely to their real-world positions, reducing correction during commissioning and supporting accurate assembly, inspection and process tasks.

DOBOT SafeSkin
Protection Before Contact
Available on the CR3AS, CR5AS and CR10AS, SafeSkin adds contactless pre-collision sensing to the CRA platform. It detects people and other conductive objects before impact, allowing the robot to initiate a safety response before physical contact occurs.
The result is a more responsive collaborative workspace, combining proactive operator protection with productive robot motion.
15 cm
Pre-collision sensing
Detects conductive objects before contact, with an effective sensing range of 5 to 15 cm.
0.01 s
Rapid Monitoring
Checks the sensing field every 10 milliseconds for rapid obstacle detection.
1 m/s
Collaborative Operating Speed
Supports human-robot interaction at speeds of up to 1 m/s.
0.1 s
Fast Response
Executes an emergency stop within 100 milliseconds once the safety response is triggered.
Stop Before Contact
Conventional collision detection responds after the robot encounters resistance.
SafeSkin monitors the surrounding sensing field and reacts as a person or conductive object approaches, adding protection before force is transferred through contact.
Keep Production Moving
SafeSkin supports collaborative operation at speeds of up to 1 m/s, rather than limiting movement to approximately 0.25 m/s. This preserves more of the robot’s productive speed while maintaining pre-collision protection around nearby operators.
The optional DOBOT VX500 combines imaging, illumination and 2.5D localisation in one robot-ready vision system.
Vision-Guided Automation.
Without the Complexity.
A 5-megapixel camera, integrated LED lighting and built-in algorithms support visual localisation, measurement, inspection and identification.
Direct CRA integration reduces component selection, wiring and software setup, with spatial compensation accuracy up to ±0.26 mm and initial applications configured in as little as 30 minutes.
BUILT FOR SYSTEM INTEGRATION
Connect the Cell.
Control the Process.
CRA combines 24 DI/DO interfaces with PNP and NPN switching and industrial protocols including Modbus TCP/RTU, EtherNet/IP and PROFINET, simplifying connection to PLCs, HMIs, tooling and the wider production line.
DobotStudio Pro supports block-based programming, Lua scripting and plug-ins for grippers, force sensors and 2D/3D vision, providing a flexible route from a standalone cobot to a complete automated cell.
