Dobot Unveils High Payload Collaborative Robot

Dobot Robotics recently released the CR20A high payload collaborative robot (cobot) based on a new generation technology architecture. The new cobot was unveiled at the Hannover Messe industrial trade fair in Germany. Specifically, the robot boasts outstanding performance, a 20kg payload capacity, a 1700mm super wide working radius, and ±0.1mm repeatability. These features make 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.

CR20A’s residual vibration is reduced by 50% during high-speed stops. Dobot’s new-generation technology architecture and advanced dynamic algorithms made this happen. More so, the robot has enhanced reliability to greatly improve production efficiency in heavy-load scenarios. Meanwhile, in palletizing applications, CR20A stacks up to 7 items per minute, and is compatible with most standard, European, and American pallet sizes, with maximum pallet dimensions of 1219 × 1219 mm.

Also, 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 cobot, safety is a fundamental requirement for CR20A. The robot innovatively adopts an electromagnetic brake protection mechanism, which automatically engages in the event of a power outage. This effectively prevents the robot’s end tool from falling and ensures 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, CR20A has a load auto-detection function.

Easy To Use. Highly Expandable.

Additionally, CR20A’s innovative dual end effector connector design reflects Dobot’s consistent product design philosophy. This allows the design to connect directly to multiple end effectors and be used with a wide range of third-party accessories.  Moreover, this feature avoids the problem of complex cable deployment that may hinder robot motion. CR20A supports Ethernet/IP and Profinet communication and seamlessly connects with other automation systems via PLC. It has 24 channels of universal IO ports that support 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 involve workpieces that weigh more than 10kg. Traditional industrial robots are difficult to deploy and lack flexibility. Also, 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 always adheres to the concept of human-robot collaboration. Also, it commits to developing safe and easy-to-use products. Thus, it promotes the widespread use of cobots 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 to 20kg payloads to fulfill a wider range of application scenarios.
