A Digital Twin-Based Obstacle Avoidance System for Quadcopter UAV

This paper introduces the development of a digital twin system designed for quadrotor UAVs (Unmanned Aerial Vehicle). It primarily utilizes AppDesigner and Unity to construct virtual models and a central server for the UAVs. Additionally, path planning for the UAVs is performed using the A-star algorithm, with improvements made to address potential collision issues in traditional algorithms. It brings forward experiments including virtual-real interaction and path flying which prove the effectiveness of the digital twin system. The system facilitates UAV control and obstacle avoidance research.
