Optimisation of surface coverage paths used by a non-contact robot painting system
This thesis proposes an efficient path planning technique for a non-contact optical
“painting” system that produces surface images by moving a robot mounted laser across
objects covered in photographic emulsion. In comparison to traditional 3D planning
approaches (e.g. laminar slicing) the proposed algorithm dramatically reduces the overall
path length by optimizing (i.e. minimizing) the amounts of movement between robot
configurations required to position and orientate the laser.
To do this the pixels of the image (i.e. points on the surface of the object) are sequenced
using configuration space rather than Cartesian space. This technique extracts data from a
CAD model and then calculates the configuration that the five degrees of freedom system
needs to assume to expose individual pixels on the surface. The system then uses a closest
point analysis on all the major joints to sequence the points and create an efficient path
plan for the component.
The implementation and testing of the algorithm demonstrates that sequencing points using
a configuration based method tends to produce significantly shorter paths than other
approaches to the sequencing problem. The path planner was tested with components
ranging from simple to complex and the paths generated demonstrated both the versatility
and feasibility of the approach
