Until now, cobots have tended to be smaller robots that primarily covered payloads of up to ten kilograms with a reach of around 1,200 millimetres. The HC20DT IP67 now considerably expands the range of applications for HRC applications: the payload of 20 kilograms combined with a reach of 1,700 millimetres enables flexible use in many different applications.

Employees can be supported in physically demanding tasks in particular, such as palletizing large boxes, crates or other stackable goods. The robot lifts such heavy loads to improve workplace ergonomics and enable employees to perform cognitively demanding tasks.

Even in harsh environments, such as machine tool loading, where the robot frequently comes into contact with cooling emulsions, the Cobot impresses with its dust and waterproof IP67 protection class. The high payload capacity also enables the simultaneous handling of several heavy workpieces with a double gripper, which is standard in CNC automation. However, applications in the food and chemical industries are also possible thanks to easy-to-clean surfaces and the use of food-safe lubricating grease.

Safety in direct contact with the operator
The new development ensures the required safety in direct contact with the operator thanks to six integrated torque sensors, which enable flexible interaction between the robot and its environment. The robot arm is designed in such a way that there is no risk of crushing fingers, for example. In terms of German and European safety standards, the Motoman HC20DT IP67 - like the smaller HC10DT - can be used as a robot with power and force limitation in accordance with the ISO TS 15066 technical specification. Depending on the risk assessment, it does not require any additional protective measures, such as a safety fence, which saves space and costs.

The YRC1000 or YRC1000micro high-performance controllers with integrated FSU and PFL boards fulfill performance level PL d category 3 according to DIN EN ISO 13849-1 and can be used for both cobots and normal Yaskawa industrial robots.

To further increase the robot's performance, it can also be operated in hybrid mode by connecting external safety technology such as laser scanners. This allows the cobot to switch between collaborative, speed-reduced and full speed in order to achieve maximum cycle times depending on the distance to the employee.

Focus on user-friendly operation
Thanks to the six integrated torque sensors and the monitoring and evaluation of external forces, it is possible to guide and program the robot arm directly by hand (Direct Teach, DT). This saves time when creating robot programs. Programming is carried out using the "Move", "Teach" and "Tool Utility" buttons on the flange. However, the new Motoman HC20DT IP67 can also be easily programmed and operated in conjunction with the Smart Pendant programming device or with a conventional hand-held operating device (Teach Pendant).

In addition to the HC20DT IP67, four other HRC-capable robot models are available from Yaskawa: HC10, HC10DT, HC10DT IP67 and later HC10DTF for the food sector. as
