A ROS2-Based Autonomous UAV Software Framework with YOLO-Driven Multi-Sensor Surveillance for Law Enforcement: A Simulation Study
Abstract: The rapid proliferation of drone technology in India and worldwide has presented new opportunities to law enforcement agencies to enhance the methods used to monitor and patrol, and respond to threats to security. This paper introduces a full software system for a ROS2-based autonomous unnamed aerial vehicle (UAV) system for law enforcement surveillance. The system, validated entirely via high-fidelity simulation using Gazebo Classic and PX4 Software-in-the-Loop (SITL), uses a combination …

Bridging Communication Gaps Among Individuals with Sensory Impairments Using Integrated Assistive Technologies
Abstract: Communication is a critical part of life, and effective communication between two or more people can sometimes be challenging due to a person's inability to communicate because of a disability such as vision loss, hearing loss, or speech loss. In the case of individuals with disabilities, they are usually given time to send out messages and receive messages, meaning they need tools that only help them with one area of …

Design and Implementation of Basic Hand Move-ment for Departmental Information Robot Using Servo Motors
Abstract: This paper presents the design and implementation of a basic hand-movement subsystem for a departmental information robot using servo motors. The proposed architecture combines an ESP32 microcontroller, a PCA9685 16-channel 12-bit PWM driver, high-torque digital servo motors, and a Jetson Nano for high-level command processing. The ESP32 acts as the low-level controller, while the PCA9685 generates synchronized PWM signals for multiple servos through the I²C interface. The Jetson Nano is …

Review on Motion Control of Departmental Information Robot
Abstract: The design and development of a departmental information robot using a differential drive system is presented in this work. To offer interactive user support, the system combines voice control, mobile application control, and simple robotic motions. A three-wheel setup is used to accomplish the motion system, with two wheels powered by DC motors and the third serving as a passive caster for stability. By regulating the driving wheels' speed and …
