Conceitos Básicos
The article proposes implementing a holonic control architecture to enable flexible cooperation between a worker and a dual-arm robot in a manufacturing workcell.
Resumo
The article discusses the concept of cooperative manufacturing, which aims to combine the advantages of human workers and industrial robots to achieve more intelligent and flexible manufacturing techniques. It introduces the holonic control architecture (HCA) as a suitable manufacturing control solution for cooperative workcells, which are self-contained modular manufacturing units containing at least one robot and one worker.
The article then presents a case study that implements the HCA concept on a cooperative workcell setup with a Baxter dual-arm robot and a worker using a Leap Motion sensor for hand gesture recognition. The key highlights of the case study include:
- The workcell setup with the hardware components (Baxter robot, Leap Motion sensor, worker and robot platforms) and the holonic control architecture deployed on them.
- The use of the Leap Motion sensor to enable the worker to interact with the control system through hand gestures, allowing them to teach the robot new tasks, start/pause/resume tasks, and provide feedback on task status.
- The integration of the Robot Operating System (ROS) for controlling the Baxter robot and the JADE multi-agent system for implementing the holonic control architecture.
- The detailed description of the different holons (worker holon, order holon, product holon, resource holon) and their interactions to enable the flexible cooperation between the worker and the robot.
- The demonstration of the holons' interaction during the teaching of a new robot task and the execution of a cooperative assembly scenario involving both the worker and the robot.
The case study showcases the feasibility of implementing the holonic control architecture to achieve the desired flexibility and adaptability in a cooperative manufacturing workcell.
