DOBOT CR3A Collaborative Robot

The DOBOT CR3A proves that high-performance collaborative automation doesn’t have to come with a premium price tag.Designed for businesses wanting to automate more while keeping their investment under control, the CR3A combines precision, speed, flexibility and a compact footprint in an affordable industrial cobot platform.With a 3 kg maximum payload and 620 mm working radius, the CR3A is perfectly suited to light-duty automation applications where accuracy and repeatability matter. Its compact size makes it particularly useful for existing production lines, workstations and machines where available space is limited.With repeatability of ±0.02 mm and maximum linear speeds of up to 3 m/s, the CR3A provides the performance required for fast, consistent and highly repetitive production tasks.

Built for Real Industrial Automation

The CR3A isn’t simply an entry-level robot. DOBOT’s CRA Series incorporates high-performance integrated joints, EtherCAT joint servo communications and a dedicated safety controller.The platform also supports common industrial communication protocols including Modbus TCP/RTU, EtherNet/IP and PROFINET, making integration with PLCs, HMIs and other industrial equipment easier.That makes the CR3A an excellent option for businesses looking to automate processes such as:

• Pick and place
• Machine tending
• Small component assembly
• Electronics manufacturing
• Screwdriving
• Quality inspection
• Testing and measurement
• Gluing and dispensing
• Sorting
• Packaging
• Laboratory automation
• Light material handling

Easy to Program and Flexible to Deploy

DOBOT’s DobotStudio Pro software supports intuitive Blockly programming for straightforward applications as well as LUA script programming for more advanced automation.DOBOT also provides ecosystem plugins and application packages for common automation processes, helping reduce development and integration time.The CR3A can be integrated with a wide range of:

• Electric and pneumatic grippers
• Vacuum gripping systems
• Machine vision
• Force sensors
• 2D and 3D vision systems
• Screwdriving equipment
• Dispensing equipment
• CNC machines
• Conveyors
• PLC-controlled equipment

This flexibility means your investment isn’t necessarily tied to one task. As your production requirements change, the robot can potentially be redeployed or reconfigured for another suitable application.

Why Choose the DOBOT CR3A?

For businesses considering their first collaborative robot, or manufacturers looking to expand automation without paying premium robot prices across every workstation, the CR3A represents a compelling combination of capability and value.

You get a modern 6-axis collaborative robot with excellent repeatability, industrial communication options, flexible programming and a growing ecosystem of compatible automation equipment.It is a particularly attractive solution where the application simply doesn’t require the payload or reach — or associated investment — of a larger robot.

The result: invest in the automation you actually need and get more value from your robotics budget.

Key Features

• 3 kg Payload – Handle components, tooling and products weighing up to 3 kg, making the CR3A ideal for light manufacturing and repetitive handling applications.
• Compact 620 mm Reach – The 620 mm working radius provides an excellent working envelope for bench-mounted automation, machine tending and compact production cells.
• High ±0.02 mm Repeatability – Excellent repeatability helps deliver consistent positioning for precision assembly, inspection, handling and manufacturing applications.Up to 3 m/s Linear Speed – The latest CRA specification lists maximum linear speed of 3 m/s, providing fast movement for applications where cycle time matters.
• Lightweight 16.5 kg Robot – At only 16.5 kg, the CR3A is relatively easy to incorporate into compact automation cells and workstations.6-Axis Flexibility – Six articulated axes allow the CR3A to approach components, machines and tooling from multiple orientations.
• Industrial Communication – Support for commonly used industrial communications including Modbus TCP/RTU, EtherNet/IP and PROFINET assists integration with existing automation equipment.
• Flexible Programming – DobotStudio Pro provides both easy graphical programming and more advanced scripting options, helping make the platform accessible to new robot users while retaining flexibility for experienced integrators.
• 20+ Safety Functions – DOBOT states the CRA platform provides more than 20 safety functions and uses a stand-alone safety controller rated PLd Cat.3.
• Optional SafeSkin Technology – DOBOT SafeSkin can be added as an optional accessory to provide pre-collision proximity sensing for appropriate applications.
• DOBOT specifies sensing up to 15 cm, depending on the application.

Technical Specifications
