DOBOT CR5A - Collaborative industrial robot arm with 900mm working radius and 5kg payload capacity

A BRIEF INTRODUCTION TO THE ROBOTIC ARM

The DOBOT CR5A is a 6-axis collaborative industrial robot arm designed for flexible, precise and high-efficiency automation tasks. As a mid-range model in the CRA Series, its 5 kg payload and 900 mm working radius provide greater reach and load capacity than the smaller CR3A, while retaining the compact design and straightforward programming associated with collaborative robots. Its design makes it ideal for handling more complex components, machine tending, precision assembly and flexible material handling.

Collaborative operation and safety

The CR5A’s collaborative design allows it to operate near people in appropriately designed applications. Pressure-sensing collision protection integrated into the robot supports detection of physical contact and can interrupt robot movement when required, contributing to safer human–robot collaboration.

The braking system has also been improved. The CRA platform uses an electromagnetic braking system designed to reduce stopping distance compared with the previous generation, providing an additional advantage in compact workspaces shared with operators or other equipment.

End effectors and machine vision

The CRA Series is compatible with a wide range of end effectors. Electric and vacuum grippers, dispensing systems, screwdriving solutions, machine-vision systems, Modbus-compatible peripherals and other automation accessories can be used to configure the CR5A for different manufacturing processes.

When integrated with a machine-vision system, the robot can also operate in workflows where the position, orientation or characteristics of a workpiece need to be determined by camera. This enables more flexible pick-and-place, sorting, positioning and visual inspection applications.

Its 5 kg payload makes the CR5A particularly suitable for automation tasks that require handling larger workpieces or heavier end effectors than smaller cobots can support, while not requiring the capacity of the larger models in the CRA Series. The 900 mm working radius provides sufficient coverage for an entire workstation, conveyor section or compact production cell.

In assembly applications, the CR5A can be used for component positioning, insertion, screwdriving and handling different parts. Its ±0.02 mm repeatability is particularly valuable in repetitive processes where consistent quality and accurate positioning are essential.

For pick-and-place and material-handling tasks, the robot can collect workpieces from conveyors, trays or storage locations and transfer them to other production equipment or process stages. When combined with machine vision, the system can also be configured to handle objects arriving in varying positions.

The CR5A is also suitable for machine-tending applications. It can automate the loading and unloading of components, service production machinery and transfer materials between different workstations. This can reduce the amount of repetitive manual handling required within the manufacturing process.

With the appropriate end effector, the robot can also be configured for gluing, dispensing, screwdriving, packaging and smaller palletising tasks. The CRA Series can additionally support applications such as welding, loading, sorting, assembly and quality inspection, depending on the selected tooling and overall system configuration.

The DOBOT CR5A provides a flexible automation solution for manufacturing environments where greater reach and payload than smaller collaborative robots can provide are required, while straightforward programming, human–robot collaboration and integration with existing industrial infrastructure remain important.

Its 5 kg payload, 900 mm working radius, ±0.02 mm repeatability, maximum linear speed of 2 m/s, 6-axis movement, collaborative safety functions and extensive I/O and industrial communication capabilities make the CR5A a versatile automation platform for assembly, machine tending, material handling and a wide range of modern manufacturing applications.
