Moving obstacle path detection for mobile robot

This paper presents a system that detects a path of moving obstacle that appear in the path of a navigating robot. The objective of the system is to avoid collision between mobile robot and moving obstacles. The system uses polar mapping to simplify the segmentation of the moving object from the background. In the transformed space qualitative extimation of moving obstacles is obtained by detec...

Moving obstacle detection from a navigating robot

This paper presents a system that detects unexpected moving obstacles that appear in the path of a navigating robot, and estimates the relative motion of the object with respect to the robot. The system is designed for a robot navigating in a structured environment with a single wide-angle camera. The objective of the system is to detect moving obstacles in order to gradually stop the robot to ...

The sonar ring: Obstacle detection for a mobile robot

Ultrasonic pulse-echo devices have shown utility for obstacle detection in numerous mobile robot research eflorts, as well as in commercial automatic guided vehicles (AGVs). A method for quickly obtaining multiple sonar range readings is presented. Thirty ultrasonic transducers are arranged in a ring and controlled by a computer. The system is predominantly composed of commercially available pa...

Monocular Scene Reconstruction for Reliable Obstacle Detection and Robot Navigation

In this paper, we present a feature based approach for monocular scene reconstruction based on extended Kalman filters (EKF). Our method processes a sequence of images taken by a single camera mounted frontal on a mobile robot. Using different techniques, we are able to produce a precise reconstruction that is free from outliers and therefore can be used for reliable obstacle detection. In real...
