Finding collision-free paths and optimized path coverage over an agricultural landscape has been a critical research problem among scientists and researchers over the years. Key precision farming strategies such as seeding, spraying fertilizers, and harvesting require special path planning techniques for efficient operations and will directly influence reducing the running cost of the farm. The main objective of this research work is to generate an optimized sequential route in an agricultural landscape with the nominal distance. In this proposed work, a novel Hybrid Dragonfly – Cuckoo Search algorithm is proposed and implemented to generate the sequential route for achieving spraying applications in greenhouse environments. Here the agricultural routing problem is expressed as a Travelling Salesman Problem, and the simulations are performed to find the effectiveness of the proposed algorithm. The proposed algorithm has generated better results when compared with other computational techniques such as PSO in terms of both solution quality and computational efficiency.
In olden day's machine (lathe or milling machine) movements were operated by manual for that trained persons were required, the workspace and the no of axes were limited one. Productions of complicated parts were difficult and batch production also impossible. The dimensions between the parts were varied so to produce batch production, testing was required. So, the cost of production was increased. Manual operated machines are now a day retrofitted by using electrical, electronics and computer software and programming technologies. The axes movements and spindle speed are driven by electrical motors. So, the no of axes can be increased which is depending upon the job's complication. Limit sensors are installed and interfaced. When a particular axis movements are exceeds its limit, the sensors will send the signals and the direction pulses are send which is used to stop the corresponding axes movement actuators. The direction and control pulses are sent from the computer to driver electronics. Actuator terminals are connected with driver electronics. Using CAD/CAM software, 3D modelling and other CNC programming parts are designed and then G-codes and M-codes are generated. The codes are executed line by line. The axes are moved with respect to the codes. Finally the one can obtain the designed parts. So, batch production will become very easy. In that particular production, dimensions between the parts are exactly similar to each other. No need to test every parts individually. Production time is less so no of products are increased.
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.
