Abstract

Wheeled robots have evolved significantly, starting from simple designs that utilized a single wheel for maneuvering to the present day, where there are numerous types capable of moving in all directions. The increasing complexity of wheeled robots today has created a learning gap for students who are just entering the world of robotics and the advanced robots that currently exist. Based on this problem, a mobile robot learning platform is needed to bridge their knowledge. The design of this platform is expected to help guide students’ learning of omniwheel robot kinematics in terms of robot model preparation, robot firmware design, communication design between the PC and the robot, and the implementation of kinematic formulas as robot commands. This platform is also designed to be universal, so it can be implemented for ready-made robots or robots built with any type of microcontroller. Comprehensive testing was performed for both movement modes in the application: forward kinematics and inverse kinematics. The forward kinematics test was carried out by assigning speed values to each motor individually. The inverse kinematics test was cariied out by assigning target position in cartesian plane. This platform is expected to serve as a valuable tool in the study of omniwheel robot kinematics.

Abstract

Background: When the rainy season arrives, the main problem faced is the drying process of shoes due to uncertain weather. Moreover, drying the shoes directly under the sun can reduce the glue's durability and damage the shoes' material.Objective: This research aims to create an automatic shoe dryer that can be monitored online and uses fuzzy logic to maintain a stable temperature to maintain shoe durability.Methods: This research uses the fuzzy Mamdani method with ESP32 as a microcontroller to regulate the temperature stability of the shoe drying box.Results: Sneaker shoes were found to dry at 52% humidity and stable temperature at ± 410C within 82 minutes. Meanwhile, leather shoes dried at 62.9% humidity, and the temperature stabilized at ±350C within 20 minutes.Conclusion: The application of Mamdani fuzzy logic has an effect in stabilizing the temperature; if the drying box is tested without using a controller, the temperature will continue to increase, and the humidity will drop quickly, resulting in shoes not being completely dry.
