The Hagisonic StarGazer Robot Localization System is a unique solution for Indoor localization of intelligent mobile robots. It analyzes infrared ray images reflected from a passive landmark with characteristic ID. The output of position and heading angle of a robot is given with very precise resolution and high speed. It is remarkably robust in environments that contain
infrared and fluorescence lights or sunshine. It is the worlds best in performance, convenience and cost.
Basic Concept:
• As a ship navigates by the stars, a mobile robot makes an autonomous navigation by artificial landmarks attached on the ceiling.
• Each landmark has an independent ID number and information on the position and angle of an autonomous robot.
How it Works:
1) The IR projector in StarGazer shoots off infrared rays at the landmarks on the ceiling.
2) Then, the landmark points reflects back the rays to the StarGazer on top of a robot.
3) At the same time, the reflected infrared rays are turned into an image by the StarGazer CMOS camera.
4) Through digital image processing, StarGazer calculates the position and angle of a robot by analyzing the acquired image.
Hagisonic StarGazer Features:
• Analyzes the image obtained when an infrared ray is reflected from a passive landmark with characteristic ID
• Composed of an IR Projector part and an image processing part
• High resolution and high speed localization of position and heading angle
• Passive landmarks are attached to the ceiling
• Not necessary to synchronize or communicate between a robot and a landmark
• Simply add landmarks to the ceiling for larger spaces
• Distinguish each room by using different IDs
• Automatic measurement and automatic calibration of distance between landmarks and ceiling height
• No battery or energy supply for landmark
• Negligible cost for extension of landmarks
• Negligibly affected by environmental lights and sunshine
• Excellent localization functionality at night
• Worlds best in resolution, convenience and cost
