Applications for visual control of a robot manipulator often require the pose (position and orientation) of an object as input for the control loop of the robot. On the other hand robot navigation usually needs the pose of the robot with respect to a world co-ordinate system. In both cases the same task of determining the pose of an object with respect to the camera has to be carried out. This ...

Mobile robots are used to operate in urban environments, for surveillance, reconnaissance, and inspection, as well as for military operations and in hazardous environments. Some are intended for exploration of only natural terrains, but others also for artificial environments, including stairways. This paper presents a mobile robot design that achieves autonomous climbing and descending of stai...

With the growth of the national economy, there is increasing demand for electricity, which forces transmission line corridors to become structurally complicated and extend to complex environments (e.g., mountains, forests). It is a great challenge to inspect transmission line in these regions. To address these difficulties, a novel method of autonomous inspection for transmission line is propos...

Sewers are aging, expensive assets that attract public attention only when they fail. Sewer operators are under increasing pressure to minimise their maintenance costs, while preventing sewer failures. Inspection can give early warning of failures and allow economical repair under noncrisis conditions. Current inspection techniques are subjective and detect only gross defects reliably. They can...

Nuclear reactor pressure vessels are often required regular inspection and maintenance in order to ensure the safety of the reactors. Failing to carry out proper maintenance could cause severe casualty. The usual way of carrying out inspection in these hazardous environments is using long reach fixed base manipulators. However, these manipulators suffer from low payload capacity and relatively ...

In Motor Vehicle Testing, Bottom Inspection is still done manually by means of the inspector entering test box to see ensure that in good condition. Weaknesses Manual Inspection, making vehicle owners unable condition directly; if there a problem at vehicle, instructs owner go down under so it takes up much time and long queue. However, with current technological developments, possible for insp...

Image-based effector servoing is a process of perception-action cycles for handling a robot effector under continual visual feedback. Apart from the primary goal of manipulating objects we apply servoing mechanisms also for determining camera features, e.g. the optical axes of cameras, and for actively changing the view, e.g. for inspecting the object shape. A peg-in-hole application is treated...

The concept of precision agriculture, which proposes farming management adapted to crop variability, has emerged in recent years. To effectively implement precision agriculture, data must be gathered from the field in an automated manner at minimal cost. In this study, a small autonomous field inspection vehicle was developed to minimise the impact of the scouting on the crop and soil compactio...

The non-destructive inspection of large bridges with autonomous systems is still an unsolved problem. One of the main difficulties is to develop a very flexible platform, which is able to move at horizontal and vertical areas and can inspect the surface. For precise inspection of concrete walls it is essential to have a manipulator to perform a 2D scan with adequate sensors. In this paper a cli...

Nowadays, wall climbing robot plays a vital role in the rapid growth of technology development. Potential applications are quite numerous, such as inspection, maintenance and cleaning operations of civil infrastructures which involve a high number of dangerous manual operations and represent a danger even for skilled workers. In view of the present situation of hazardous inspection environment,...
