Area of Science:

• Robotics and Automation
• Sensor Technology
• Industrial Engineering

Background:

• Autonomous industrial trucks require precise positioning for safe and efficient operation.
• Conventional systems like GPS, LiDAR, and cameras face limitations in industrial environments.
• Ultra-Wideband (UWB) technology presents a potential solution for enhanced navigation.

Purpose of the Study:

• To evaluate the effectiveness of UWB technology for autonomous industrial truck positioning.
• To compare UWB performance against GPS, LiDAR, and camera systems.
• To assess UWB accuracy and reliability under various industrial conditions.

Main Methods:

• Conducted experiments in a real factory environment with autonomous industrial trucks.
• Assessed UWB positioning accuracy at different distances and under diverse conditions.
• Compared UWB performance with GPS, LiDAR, and camera systems, noting environmental impacts.

Main Results:

• UWB achieved 0.2 cm accuracy 99% of the time, significantly outperforming GPS (10 cm) and LiDAR (5 cm).
• UWB maintained high accuracy in environments with metallic interference and non-line-of-sight issues.
• GPS and LiDAR efficacy decreased by 40% and 25% respectively in challenging conditions where UWB excelled.

Conclusions:

• UWB technology demonstrates superior accuracy and reliability for autonomous industrial trucks compared to conventional systems.
• UWB's robustness in adverse industrial environments makes it ideal for enhancing operational safety and efficiency.
• UWB offers low power consumption and efficient multi-user operation without interference, paving the way for advanced industrial automation.
