Abstract

This study aims to design and analyze a suiTable an automatic motorized cat feeder for large cage sizes. Using the Internet of Things (IoT) based cat feeder, can be enhanced with monitoring and controlling functions. The Internet of Things (IoT) develops a vast network of devices that exchange data regularly. Therefore, Consumers are increasingly interested in smart home devices and gadgets, which allow them to connect all of their devices for increased convenience, comfort, energy efficiency, and, most importantly, practicality, which is one of the project's main goals. The cat feeder system developed in this research is separated into two primary sectors which are measurements and control while the design structure is focused on the structure inappropriate position to be placed on a large cage size. To create an automatic cat feeder for large cage size, design research is conducted to comprehend the design structures, functions, materials, and applications of the cat feeder, and then design improvement and design for prototyping are implemented using SolidWork software. Secondary data were gathered and used as benchmarks to satisfy the intended functions of the cat feeder. Material selection and plateform design have been made as part of design modification and improvement. Furthermore, finite element analysis is carried out to analyse the cat feeder mounter and to ensure the fabrication of a cat feeder that can withstand maximum loads of up to 10 kilograms. Static analysis is used, and the result is a factor of safety of 28.57. Furthermore, prototype design verification is verified according to factor of safety and benchmarks from secondary data interpretation to fulfill project objectives. This shows the value of 28.57 factor of safety is safe under the design load. Polyamide-12 nylon powder are selected as material except mounter knobs and arduino components. Thus, the main prototype fabrication method is conducted by using SLS 3D printing machine. Arduino system code is writted by using Arduino software. Moreover, measuring instruments are used for dimensional inspection by manual method. Cat feeder is assembled and tested after fabrication. A usability test is conducted in order to gather user feedback, confirm the cat feeder's intended uses, and spot any unknown design flaws. Overall, the cat feeder is an alpha prototype, meaning that ongoing design improvement is required to satisfy the demands of the specific requirent. In the end, cat owners don't have to worry about feeding their pets and can watch over their caged cats from a distance.
