![]() ![]() Intelligent AGVs, though, use computer vision systems, aided by other sensors, to work with more flexible paths. However, magnetic or RFID-guided systems – using Radio Frequency Identification tags – require pre-planned installations of their trajectories, making it difficult to change routes, reducing the flexibility of the manufacturing environment. The commercial magnetic sensors feature 1 mm resolution and a refresh rate of 100 Hz. state that a “popular and affordable version is still a version using a magnetic tape”. About the guidance technology, Fedorko et al. There are several types of sensors used to guide AGVs such as electromagnetic and optical. Furthermore, the experiments confirm sensor pertinence for the proposed control system. ![]() In addition, it discusses the influence sources on camera image as a position sensor. This paper’s main contribution is a qualitative and quantitative analysis for the different sensor configurations. The AGV uses a USB camera with different image processing settings-different morphological filters structuring elements shapes and sizes, and three different image resolutions-to analyze the factors that affect line detection and control processing. We performed the experiments with a small AGV prototype on an eight-shaped lane, varying both camera parameters and AGV parameters, such as linear speed. It presents a qualitative analysis of a USB camera as sensors for AGV control, not yet a common industrial application. This work addresses AGVs driven by passive floor demarcations. In this sense, it is necessary to ensure the sensor is adequate to control system requirements. AGV control techniques are not new, but new sensors’ applications are possible, such as USB cameras. ![]() It leads to smaller corridors and leaner plants, to more relaxed shipment devices, and to greater safety in the transport of fragile loads, for instance. Proper position control and movement give an AGV greater movement accuracy and greater lateral oscillations stability and vibration. ![]() The increasing use of Automated Guided Vehicles (AGV) in the industry points to a search for better techniques and technologies to adapt to market requirements. ![]()
