Abstract

An Automatic Guided Vehicle (AGV) is an automated vehicle used to support the delivery of food and beverages in restaurant service systems, where manual methods still carry risks of delays and spillage. This study designs and builds a line-following AGV using a Quality Function Deployment (QFD) approach with screening and scoring concepts to translate user needs into the technical specifications of the device. The research stages include needs identification, mechanical and electronic design, Arduino programming, and track testing. The AGV is capable of following a path with high accuracy using infrared sensors, automatically stopping at the destination, and detecting obstacles via ultrasonic sensors, with a buzzer serving as a delivery indicator. Test results show stable delivery performance with a relatively low spillage rate of 10%–13.33%. The AGV measures 40 × 30 × 43.6 cm, uses a 12 V battery, two DC motors, has a speed of 0.25 m/s, a maximum load capacity of 2 kg, and is controlled by an Arduino Uno with an integrated sensor system.

Abstract

This study presents a redesign of the drum brake system on a Honda Supra motorcycle using a reverse engineering approach. Innovation was carried out by utilizing aluminum alloy as the brake shoe material to reduce weight and enhance corrosion resistance. In addition, a Non-Asbestos Organic (NAO) brake lining was applied, known for its high friction performance and excellent wear resistance. Design modifications include increasing the rib thickness of the brake shoe to reduce stress concentration and adding a chamfered surface to the brake lining, with a thickness of 5 mm. Structural strength was evaluated through Finite Element Analysis (FEA), using von Mises stress as the performance indicator. The results indicate that the redesigned structure and material successfully reduce stress concentration.
