Programming and execution of skill-based human-robot-crane collaborative tasks

Summary

Researchers present a CAD-based programming and execution system for parameterized robot skills, using a modified Behavior Tree and event-only communication. A demonstration shows an operator coordinating an overhead crane and a manipulator to insert a crane-supported heavy object into a goal, addressing flexibility and robustness for variable production and indoor logistics.

Abstract:Highly varying production sets increasing challenges for robotic manufacturing and indoor logistics. New capabilities for agility, flexibility, and robustness are needed. Robot skills, integrating motions, tool operations, and sensor perceptions consistently provide an execution mechanism for a versatile set of tasks with varying parameters. In this paper, easy-to-use CAD-model based programming and execution system for parametrized skills and skill monitors is showcased. The execution control structure is dynamic and parametrized, based on a modified Behavior Tree, where only event based communication is used. A human-robot-crane collaborative skill is shown as a test example, where a human instructs an overhead crane and a manipulator in inserting a heavy object supported by the crane, and guided by the manipulator, into the goal.
