This paper presents a system for autonomously delivering a quantum of fluid to individual plants in a vegetable crop field, using a fine spray nozzle attached to a manipulator arm on a mobile robot. This can reduce input cost and environmental impact while increasing productivity for applications such as micro-nutrient provision, thinning and weeding. The Ladybird platform is introduced and a p...

The purpose of this paper is to model and simulate a 6 DOF robotic system with revolute joints in order to optimize the motion law which results in uniform coating deposited by spray pyrolysis. The structure and the complexity of the robotized system are determined by the necessary movements in the spray pyrolysis process. The nozzle (end-effector of the robot manipulator) has two translations,...

The macro characteristics and configurations of induced shock waves of the supersonic sprays are investigated by experimental methods. Visualization study of spray shape is carried out with the high-speed camera. The macro characteristics including spray tip penetration, velocity of spray tip and spray angle are analyzed. The configurations of shock waves are investigated by Schlieren technique...

BACKGROUND Spray boom systems, an alternative to the predominantly-used spray guns, have the potential to considerably improve crop protection management in glasshouses. Based on earlier experiments, the further optimization of the deposits of a medium spray quality extended range flat fan nozzle type using easy adjustable spray boom settings was examined. Using mineral chelate tracers and wate...

A ground source heat pump system (GSHPS) utilizes a relatively stable underground temperature to achieve energy-saving for heating and cooling in buildings. However, continuous long-term operation will reduce the soil temperature in winter, resulting in a decline in system performance. In this research, in order to improve the system performance of a GSHPS, a ground heat pump system integrated ...

Passive wireless sensors have the advantages of operating without a power supply and remote sensing capability. Hence, they are very suitable for some harsh environments, such as hermetic environments, rotating parts, or very high temperature environments. The spray painting workshop is such a harsh environment, containing a large amount of flammable paint mist and organic gas. Aiming at this s...

The security and stability of the pump system have received extensive attention in hydraulic engineering, especially in nuclear system. Transient operations, such as the rapid closure of a valve, a sudden switch over and start procedure of pumps and pump failure will cause sudden flow variation in the pipe system. This phenomenon, known as water hammer, will cause transient effects on the pump....
