Robotic construction system for shotcrete digitization and automation through advanced perception, cognition, mobility and additive manufacturing skills prCWA

Scope

This document is applicable to the following cognitive robot platforms that address the complete chain of shotcrete application for autonomous construction, maintenance and monitoring activities of infrastructures:
a) an inspection and reconnaissance mobile manipulator (IRR) with cognitive perception capabilities that fuse multimodal sensors or the high precision modelling of the construction site endorsed with a metal additive manufacturing (AM) manipulator to perform reinforcement of metallic rebar;
b)a shotcrete and finishing mobile manipulator (SFR) to perform wet shotcrete through concrete spay-casting, relied on visual guided robotic manipulation.
The planned CEN Workshop Agreement:
– concerning the mobile manipulators:
– provides terms and definitions and describes the characteristics of mobile manipulators and their components
– specifies requirements and evaluation methods for the performance of mobile manipulators
– specifies requirements for cement mix and materials
– concerning the construction site:
– defines uses cases: construction of ground support walls, repair of piles or beams, inspection and monitoring of bridge post-tensioned boxes and construction of culverts or service tunnels
– provides guidelines for mapping and navigation strategies
– sensor deployment per construction site
– concerning the digitization, deals with:
– autonomous decision making
– interaction with BIM
– digital twin and methods to transmit and collect data
– IoT Integration with other subsystems. The planned CEN Workshop Agreement does not apply to safety requirements for mobile manipulators.
