Abstract:

In order for an item of robotic construction plant to function it must be precisely located on site relative to its task. This can be achieved through the provision of a global or site reference framework and of a local or task speicific reference framework. In green field applications in the absence of obstructions to the line of site, both these objectives can be achieved by means of triangulation based on the use of lasers or video systems. However, as the work on site progresses line-of-sight techniques become increasingly disadvantaged by the presence of obstructions and other techniques will be required. Given the cost of systems of the accuracy information by these means such as global systems may well need to be supported by other, task specific, systems designed to provide the necessary information on location and attitude. The paper considers a system under development in the engineering departmnt at Lancaster University which is intended to provide all the necessary information to enable automatic operation of a range of robotic plant. The proposed ystem utilises a single laser source as reference and is capable of measuring all the degrees of freedom associate with the vehicle used to deploy an item of plant such as a robotic axcavator arm.
