It is necessary to improve methods for structural risk assessment. This will enable operators of large infrastructures to meet new standards for seismic risk assessment at a lower cost. The approach will be to develop a low-cost climbing robot capable of reaching remote parts of large structures; sensors for structural inspection and instrumentation; and mission management systems. The results will be evaluated via field tests. Their impact on structural risk assessment capabilities will be quantified and disseminated.
The key objective is to remove the need for human climbers, who are scarce and expensive, and not well-suited for carrying out objective, repeatable inspection protocols.
The technical objectives are:
to develop a low-cost climbing robot to convey sensors to remote parts of large structures;
to develop robotic methods of attaching sensors to the structure;
to develop advanced sensors for surface inspection using visual, acoustic, magnetic and radar sensing techniques;
to develop a user interface supporting robot navigation, data acquisition and display, and analytical facilities;
to capture best practice for objective and repeatable inspection before and after seismic shocks;
to quantify and disseminate benefits for the ability of operators to meet structural assessment standards.
The main tasks will be to capture the current state of the art in structural assessment as a baseline:
to capture user requirements and technological constraints, and derive a specification of the ROBOSENSE system;
to develop the core technologies, including the robot vehicle, robotic instrumentation mechanism, sensor payloads, and mission management software;
to integrate the technical components, and manufacture enough robots and sensors to enable end-user evaluation;
to evaluate the technology via field tests, developing and capturing an objective, repeatable structural risk assessment protocol, and quantifying the resulting benefits;
to disseminate the results of the project, especially its impact on best practices in structural risk assessment, and to prepare for exploitation.
State of the art and requirements captured, system designed;
Core robot, sensors and software technology developed;
Evaluation systems manufactured and integrated, field tests planned and baseline information gathered;
Evaluation completed, benefits measured against quantitative yard sticks;
Final project results will be a robotic inspection system including vehicle, sensors and software; and an objective, repeatable robotic structural assessment protocol.
