Design and construction of an omnidirectional mobile - displacement laser cutter: Trajectory calculation from machine vision

摘要

Current technologies and methods for cutting pieces of a raw material, have a big limitation, and without despising its efficacy and precision, its scope and area of work limit the materials that are possible to manufacture in only process stage; This is a task of an area of research how to solve this disadvantage without losing the efficiency of the past technologies. The solution appeared inside the group of investigation about Mechatronics Design; it was to design and construct a mobile robot half size of the traditional ones, that is able to cut on the plate of expanded polystyrene. The trajectory of this device not only can be programmed, also is possible to import files, the robot has a module to processing images which recognizes and segments the benchmarks of court that are needed for the piece. This is an economic method, since peripheral devices of manufacture and control are also very rentable and of high performance, as it is the card of embedded development, RaspberryPi.
