DOBOT CR12A - Collaborative industrial robot arm with 12kg payload capacity and 1200mm Working Radius

ROBOT ARM OVERVIEW

The DOBOT CR12A is a 6-axis collaborative industrial robot arm designed for automation applications that require higher payload capacity, an extended working range and precise, repeatable operation. With a maximum payload of 12 kg and a 1200 mm working radius, it can handle larger workpieces, heavier grippers and more substantial end effectors, making it suitable for machine tending, material handling, palletising, assembly, packaging and a wide range of other industrial automation tasks.

The CR12A provides ±0.03 mm repeatability, supporting consistent positioning throughout extended production runs. This is particularly important in assembly, machine tending, loading and dispensing applications where the same movement must be reproduced accurately across a large number of cycles.

With a maximum linear speed of up to 2 m/s, the CR12A provides a strong foundation for fast material-handling and production cycles while maintaining its higher payload and extended working range. Actual operating speed depends on the workpiece, end effector, safety configuration and requirements of the individual process.

The robot arm weighs approximately 39.5 kg, providing a relatively compact automation platform despite its 12 kg payload capacity. This can be particularly advantageous in facilities where installation space is limited or where the robot must be integrated alongside existing production equipment.

Its 6-axis architecture provides extensive freedom of movement. J1, J2, J4, J5 and J6 offer ±360° rotation, while J3 provides a ±160° range of motion. This enables the robot to approach workpieces from multiple directions, follow complex trajectories and perform operations in different orientations.

The J1 and J2 axes can reach speeds of up to 150°/s, while the remaining axes can operate at up to 180°/s and 223°/s. Advanced motion control supports fast yet smooth robot movement, which is particularly important when handling larger workpieces, following extended paths or executing more complex automated workflows.

Advanced Control and Collaborative Safety

The CRA generation incorporates highly integrated joint modules and advanced control algorithms. The platform has been developed to support shorter cycle times, reduced vibration and smoother trajectory control, providing advantages in repetitive material handling, assembly and machine-tending applications.

The CR12A’s collaborative design supports automation systems where human operators and robots work within closely connected production processes. The CRA platform provides configurable safety functions, including virtual workspace boundaries and safety strategies that can be adapted to the individual application. The final robot cell must always be designed and validated according to an application-specific risk assessment.

An electromagnetic braking system activates within 18 ms in the event of an unexpected power loss, minimising arm displacement and protecting workpieces and equipment.

Intuitive Programming and Control Capabilities

Programming is supported through the DobotStudio Pro software environment. Graphical Blockly-based programming allows operators to create automation workflows using visual programming blocks, enabling straightforward robotic applications to be configured without extensive coding experience.

For more advanced applications, LUA script programming supports sophisticated program logic, conditional workflows, communication functions and customised automation routines. This allows the CR12A to be used in everything from relatively simple robotic workstations to complex industrial automation systems.

Hand-guided teaching is another important feature of the CRA platform. Operators can physically guide the robot arm into the required positions and save those points as part of the robot program. This is particularly useful in manufacturing environments where tasks frequently need to be modified or adapted for different products.

Additional interfaces are available directly at the robot’s end effector. The CR12A provides two digital inputs, two digital outputs and two analogue inputs, with the latter sharing functionality with the RS485 interface. This simplifies direct integration of intelligent grippers, sensors and other active end-of-arm tooling.

Its extensive communication capabilities mean that the CR12A does not need to operate as an isolated robot. It can be integrated into PLC-controlled production lines, automated machining cells, conveyor systems, machine-vision applications and more complex automation architectures involving multiple machines or robots.

Electric and pneumatic grippers, vacuum systems, force/torque sensors, screwdriving equipment, dispensing systems and other end effectors can be selected according to the requirements of the individual application.

Machine Vision and Complex Application Areas

When combined with machine vision, the CR12A can determine the position and orientation of workpieces before handling them. This enables the robot to work with components that do not always arrive in exactly the same location or orientation. Vision integration is particularly useful for sorting, bin picking, positioning, inspection and quality-control applications.

One of the main advantages of the 12 kg payload is that sufficient useful capacity can remain available even when heavier end-of-arm tooling is installed. This can be especially important in machine-tending applications where both a robust gripper and the workpiece itself must be included in the robot’s total payload calculation.

For CNC machine tending, the CR12A can automatically collect an unfinished workpiece, load it into the machine and remove the finished component once the machining cycle is complete. Its 1200 mm working radius can allow the robot to reach several process positions, trays or conveyor sections from a single installation point.

In pick-and-place applications, the robot can transfer components between production lines, trays, pallets, storage areas and manufacturing equipment. Its 12 kg payload means that it can handle not only smaller individual components but also larger products or multiple items simultaneously when equipped with an appropriate end effector.

For assembly processes, the CR12A can position, insert, fasten and move components. Its 6-axis movement allows workpieces to be approached from different angles, while ±0.03 mm repeatability supports consistent operation across repetitive production cycles.

The CR12A is also well suited to packaging and palletising applications. Its 12 kg payload enables it to handle boxes, packaged products, trays and other units, while the 1200 mm working radius provides a practical working area for transferring items between conveyors and pallets.

With appropriate tooling and process equipment, the robot can also be configured for screwdriving, gluing, dispensing, polishing and other specialised applications. The CRA platform’s open communication and peripheral-integration capabilities simplify the development of customised robotic solutions.
