Acquisition of Obstacle Avoidance Behaviors for a Quadruped Robot Using Visual and Ultrasonic Sensors

摘要

In this paper, an obstacle avoidance method is described for a quadruped walking robot by using camera image and ultrasonic sensors. A single camera is used to acquire the rough information of three-dimensional obstacle, while some ultrasonic sensors are used to obtain the accurate information of the obstacle. Thus, the obstacle is efficiently measured by combining these sensors properly. The effectiveness of the proposed method is verified for several experiments, in which TITAN-VIII is adopted as an experimental setup. The quadruped robot can arrives at the target with repeat of these actions. The effectiveness of the presented method is verified through some experiments
