Recently the industries provide visual inspection processes in the plants for keeping and guaranteeing product quality. Many visual inspection processes are normally operated by the manual visual inspection. The results of the manual visual inspection are often unstable because the results are depended on the inspection worker skill. Currently the automated visual inspection technologies are ge...

Inspection of welding/bending in ventilation ducts for holes and surface cracks in the sheet metal is very important after manufacturing them and also during maintenance after installation. This paper deals with the design of an antenna based sensing robot (without a microcontroller) for inspection and imaging of ventilation ducts. It uses its antenna to sense the obstacles on its path. The mot...

In Japan, aging of infrastructure and shortage the labor have become social problems. It is a socially demanded, to realize efficient inspections maintenance. this paper, we mention on “infra-robot evaluation project'' conducted by MLIT in 2014-2015. Then, based its results, consider superiority robot-based inspection bridges, proper procedure for practical inspection. Finally, propose performa...

This paper describes a systematic approach to using robots to automate making difficult measurements in real-world environments. The approach is illustrated by a detailed description of the architecture’s actual application to inspection of commercial aircraft for skin cracks and lap joint delamination. Several robot designs are evaluated; a small mobile robot with suction cup feet is found to ...

This paper addresses the following inspection problem: given a known workspace and a robot with vision capabilities compute a short path path for the robot such that each point on boundary of the workspace is visible from some point on the path. Autonomous inspection, such as by a flying camera, or a virtual reality architectural walkthrough, could be guided by a solution to the above inspectio...

This paper describes research towards the development of a robotic system for the automated inspection of steel plates. Such plates are inspected extensively during manufacture and fabrication. This inspection is often carried out manually in hazardous environments by skilled personnel. Such difficult conditions may reduce the operating ability of technicians, leading to poor performance and lo...

The sewer inspection robot MAKRO is an autonomous multi-segment robot with worm-like shape driven by wheels. It is currently under development in the project MAKRO-PLUS. The robot has to navigate autonomously within sewer systems. Its first tasks will be to take water probes, analyze it onboard, and measure positions of manholes and pipes to detect polluted-loaded sewage and to improve current ...
