Navigation systems based on animal behavior have attracted considerable attention in the past few years. Navigation systems using artificial pheromones have not been extensively developed. Therefore, this paper presents a model for realizing an artificial pheromone system by using data carriers and autonomous robots. By introducing an artificial pheromone system composed of data carriers and autonomous robots, a robotics system creates a potential field for navigation. First, we develop pheromone density in a discrete nominal model. Then, we extend the model to deal with a random layout that is suitable for real conditions of data carriers. For demonstration of the effectiveness of our proposed model, computer simulations and hardware implementations are performed. The artificial pheromone potential field constructed using our proposed model can be used for the navigation of autonomous robots.
The presence of recycled plastic materials for the 3D printing process expects that the production process will be more environmentally friendly and solve the problem of plastic waste globally. However, recycled plastic as a filament material in the 3D printing process is still limited. One of the ways to make recycled plastic filaments is by extrusion. This research aims to optimize the extrusion process parameters in the manufacture of recycled plastic filaments (Polypropylene) that have never been conducted before. The extrusion process was analysed using the Taguchi and ANOVA methods. The results of this study indicate that the spooler speed of 4 rpm, extrusion speed of 40 rpm, and extrusion temperature of 200°C in the parameter setting produce an average filament diameter of 1.6 mm. However, filaments made from Recycled Plastic (Polypropylene) have a rough and easily curved surface, so further research is needed.
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.
