£oWith our country's labor cost increase and forestry operations to improve the degree of automation, the automatic picking device will be gradually adopted to pick fruit in the future. This paper discusses the design process of intelligent mobile platform, five axis manipulator, end effector, electrical control device which belong to the automatic fruit picking device. The device is installed in the automatic navigation system and visual identity system, can accurately locate the position and pick fruit. The CAD/CAE software device was mainly used to design and analysis model, and design efficiency, feasibility and scientific were improved. According to the current development trend of fruit species gradually increased, the manipulator hand can adjust, which can pick the different shapes of fruits, and is installed with a visual sensor, pressure sensor, position sensor in the manipulator, and the finger stress analysis was made. In addition, the application of S7-200 model of PLC and pneumatic technology is used in the picking device, so that the overall structure is compact, more stable.
Health management is the primary technical approach to ensure the safety and reliablity in aircraft. The degradation process of Mechanical Electrical and Hydraulic Integration (MEHI) systems have the characteristics of the hybrid system. In this paper, we firstly review the research on the hybrid systems in recent years, then based on the hybrid system theory , present the fault diagnosis and prediction for MEHI system in aircraft. Lastly proposes a fusion method for predicting the failure time based on the data-driven and system physical characteristics.
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.
