![]() ![]() This paper describes the design and implementation of a robot control system on a hardware platform based on a programmable logic controllers (PLC). Many industrial applications require some sort of automated visual processing and classification of items placed on moving conveyor. In addition, present review also discusses about a few technologies for environment friendly and economi-cally effective options in spray painting. These databases can significantly assist the researchers who are looking for this solution or working on the mentioned application. In this regards, present review accumulates the various aspects of recent automatic techniques, working methodologies and innovative tech-nologies used in the spray painting robots by considering the various mechanical and electrical components. Still, there is a need to increase the effectiveness, precision, durability and reliability in such automatic techniques. Many advancements in the sphere of painting robots have been discovered and utilized for high rise buildings painting, wall painting and other surface painting. Present review highlights the various robotic technologies used for solving the need to paint any surface. ![]() ![]() ![]() Since the last decade, human efforts have replaced manual works in terms of automatic (robotic) solutions dramatically for safety and precision purposes. The PWM control of the DC motor provides the performances settled at the designing stage. The running duty of a conveyor belt may be modified by modifying the duty-cycle value of the PWM signals that controls the transistors of the H-bridge that supplies the DC motor. Unlike other driving systems of conveyor belts, this system allows the optimization, by trials, of their running duties. The purpose of the experimental stand consists of studying the running characteristics of the conveyor belts under laboratory conditions, so that, further on, such driving systems can be implemented to industrial applications as well. For controlling the ARDUINO UNO board, a program has been issued in the LabVIEW 2013 programming environment. The PWM signal is generated by an ARDUINO UNO board, equipped with an Atmega 328 microcontroller. For supplying the DC motor an H-bridge has been used that allows the reversal of the motor rotation wise. This work presents an experimental stand for the PWM control of a DC motor used for driving a conveyor belt. ![]()
