DOBOT COBOT CR5AS - Collaborative Industrial Robot Arm with 900mm working radius, 5kg payload and SafeSkin accessory

The robot offers a maximum linear speed of 2 m/s and ±0.02 mm repeatability, enabling fast and consistently reproducible motion in assembly, material handling, machine tending and other industrial processes. With a weight of 25 kg, the CR5AS remains a relatively compact and flexible robotic platform despite its larger working range.

Its 6-axis configuration provides a high degree of freedom. The J1, J2, J4, J5 and J6 joints offer a ±360° range of motion, while J3 provides ±160°, allowing the robot to approach workpieces from different directions and execute complex trajectories.

The CRA generation features an upgraded servo system and dynamic control algorithms. Compared with the previous CR Series, the new system provides increased joint speed, reduced vibration and shorter cycle times, supporting greater productivity in applications where both collaborative operation and production efficiency are important.

The robot has an IP54 protection rating, providing resistance against dust and splashing water in many standard industrial environments. Its operating temperature range is 0 to 50 °C, while its maximum noise level is 70 dB(A).

The CR5AS’s compact form factor makes it easy to integrate into existing production lines, compact robotic cells and narrower manufacturing spaces where available floor space is limited.

SafeSkin operates using electromagnetic sensing. The system monitors changes within a detection field surrounding protected sections of the robot arm, allowing it to respond to approaching human bodies, metals, liquids and other detectable objects.

The effective detection range is approximately 5–15 cm, the detection cycle time is 0.01 seconds, and the emergency-stop execution time is 0.1 seconds.

The system is primarily applicable around the J4, J5 and J6 joints. The workflow can remain suspended while the obstacle stays within the protected area, and the robot can resume the program once the workspace becomes clear again.

One of the CR5AS’s key advantages is straightforward deployment and teaching. The system can be commissioned quickly, while hand-guided teaching allows the operator to physically move the robot arm into the required positions and save these points for use within an automated workflow.

Teach & Playback programming enables robot movements to be taught directly without requiring advanced programming knowledge. The operator can guide the robot arm manually to the desired positions, save them as coordinate points and then use them repeatedly as part of an automated process.

The CR5AS also supports graphical block-based programming, allowing robot movements, logical conditions and different operations to be configured through visual elements. For more advanced development, Python-based programming is available for creating custom automation logic, algorithms and integrations with external software systems.

The robot supports multiple motion modes, including joint-interpolated, linear-interpolated, arc and circular movement. This enables not only simple point-to-point operations but also applications requiring continuous motion along precisely defined paths.

The CR5AS control system provides digital and analogue I/O together with industrial communication capabilities. TCP/IP, Modbus and RS485 communication enable the integration of PLCs, sensors, production equipment, grippers and other automation components.

Additional interfaces are available at the robot flange, allowing intelligent grippers, vacuum end effectors, dispensing tools and other active peripherals to be connected directly to the robot arm. By selecting the appropriate end effector, the same CR5AS platform can be configured for a wide range of manufacturing processes.
