Abstract

A safe is a place used to store valuable items. Generally, safes use buttons to open the door. However, using buttons that only require entering a password is considered less secure. Therefore, a device has been created to enhance the security of the entered password. The device utilizes Arduino as the central data processing unit for user input and an Android smartphone as the device for entering the password. The security is implemented using the cryptographic technique known as One Time Pad, where the user is prompted to input the password to be used. During the password storage process, the password is encrypted before being stored. To use it, the user simply enters the stored password into the system. If the device is forcefully tampered with, a thief attempting to retrieve the password will be unable to understand the stored password within the device, as it has undergone encryption. With this dual security measure in place, it is expected that the safe will be even more secure.

Abstract

Robotics has become an ever-growing field with increasingly diverse applications in various industries. One interesting application is the development of delivery robots that can follow specific paths on surfaces using black markings as a guide. This research aims to design and implement a microcontroller-based black mark following goods delivery robot prototype. This robot prototype uses a TCRT5000 sensor to read black markings placed on the bottom of the robot. Using this robot is very easy by providing a battery for the robot's power source. The TCRT5000 sensor is a reading sensor for following the path. The FC-51 IR sensor as an obstacle detection sensor is in front of the robot for temporary stops when the robot is walking. The TTP223B touch sensor calibrates the robot at the start and end of the robot's work, inputting the additional number of stops when the robot is in a temporary state. This robot is easy to use because the operation is easy to understand, making the robot easy for ordinary people to use.
