ROS2-TMS for Construction: CPS platform for earthwork sites

-Implementation of Task Management Mechanisms-

Abstract

In recent years, the shortage of human resources at earthwork sites has been accelerating due to industrial accidents and the declining birthrate and aging population. Against this background, Our lab is developing a CPS platform called ”ROS2-TMS for Construction” as a system that simultaneously improves the efficiency and safety of earthwork work. This paper introduces a newly developed task management mechanism as a continuation of the ROS2-TMS for Construction development. The task management mechanism is a mechanism for operating actual construction machinery based on scenarios called task sequences given to ROS2-TMS for Construction.In this time, I adopted the Behavior Tree as the task scheduler and incorporated it into ROS2-TMS for Construction with some extensions according to the ROS2 specification. An overview of the extensions of Behavior Tree we adopted to task management mechanism of ROS2-TMS for Construction will also be explained in this paper.
