Positioning technologies are useful in a great number of applications, which are oriented for pick and place robots, manipulation of machine tools, especially on machines oriented for artificial vision and detection systems, such as vision-guided robotic systems and object existence in a limited environment. Due to the high demand of those applications, this chapter presents digital control theory application using a laser positioner, which obtains 3D coordinates in a defined field of view. Using the LM629N-8 motion controller, representing the main digital controller for the motion task of the laser positioner as an active element, which is analyzed via modeling and simulation using Matlab-Simulink. Additionally, this chapter focuses on some of the principal sources of uncertainties that exist in a laser scanning system and mainly on the receptive part of such system, which is driven by a brushed DC motor. The processed signal will be analyzed in different environmental conditions to analyze how it is affected by the instability characteristics of this main actuator.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
