Dobot Robotics Unveils CR20A High Payload Collaborative Robot at Hannover Messe

April 17 2023, Dobot Robotics officially released the CR20A high payload collaborative robot based a new generation technology architecture at the Hannover Messe industrial trade fair in Germany. The robot boasts outstanding performance, a 20 kg payload capacity, a 1700 mm super wide working radius, and ±0.1 mm repeatability, making it suitable for heavy load handling, packaging, and palletizing, as well as large-sized workpiece machining and long-seam welding in complex scenarios.

Wide Radius. High Payload. Greater Efficiency.

Based on Dobot's new generation technology architecture and advanced dynamic algorithms, the CR20A's residual vibration is reduced by 50% during high-speed stops. The robot has enhanced reliablility to greatly improves production efficiency in heavy-load scenarios. In palletizing applications, the CR20A is capable of stacking up to 7 items per minute, and is compatible with most standard, European, and American pallet sizes, with a maximum pallet dimensions of 1219 mm × 1219 mm.

Dobot has developed dedicated process package software for palletizing, welding and other complex tasks. By combining the CR20A with these process packages, users can quickly customize and deploy the solutions with a few simple setup steps, meeting the demands of small-batch and flexible production.

Reliable Safety Features.

As a high payload collaborative robot, safety is a fundamental requirement for the CR20A. The robot innovatively adopts an electromagnetic brake protection machanism, which automatically engages in the event of a power outage, effectively preventing the robot's end tool from falling and ensuring no displacement occurs during start-up and shut-down, thus ensuring safe robot operation.

In actual production applications, the robot's actual load may change due to process adjustments. To avoid problems caused by significant load deviations, the CR20A has a load auto-detection function.

Easy To Use. Highly Expandable.

Dobot's consistent product design philosophy is reflected in the CR20A's innovative dual end effector connector design, allowing it to connect directly to multiple end effectors and be used with a wide range of third party accessories. This feature also avoids the problem of complex cable deployment that may hinder robot motion. The CR20A supports Ethernet/IP and Profinet communication, seamlessly connects with other automation systems via PLC, and has 24 channels of universal IO ports that support for PNP/NPN switching, providing customers with a smooth automation experience.

In industries such as automotive, home appliances, and logistics, many production processes such as handling, assembly, and palletizing involves workpieces that weigh more than 10 kg. Traditional industrial robots are difficult to deploy and lack flexibility, and lightweight collaborative robots are unable to meet the requirements of payload and arm length. Therefore, the CR20A robot, with its high payload and wide working radius advantages, becomes the best choice for solving these problems.

As a leading manufacturer of intelligent robots, Dobot has always adhered to the concept of human-robot collaboration, committed to developing safe and easy-to-use products, and promoted the widespread use of collaborative robots in more industries and scenarios. The launch of the CR20A high payload robot marks another milestone in Dobot's product line, forming a complete product matrix that covers 0.5 kg to 20 kg payloads to fulfill a wider range of application scenarios.
