Enhanced obstacle recognition method based on complementary use of multiple sensors

Various robot platforms have been designed and developed to perform given tasks in hazardous environments for surveillance, reconnaissance, search and rescue, etc. A robot must be capable of overcoming and navigating these diverse environments. Awareness of the environment surrounding the robot so as to detect and avoid obstacles is a very important technology. For this purpose, ambient space recognition techniques are needed by complementarily using multiple distance sensors to enhance autonomous driving performance of the robot.
