چکیده

This paper proposes an efficient obstacle recognition system for helping the navigation of mobile robots. It is especially suitable to operate in connection with agent-based control architectures, for its suitability to be inserted in the whole control system. The capability of object recognition also allows defining more complex behaviors to be programmed, based on the recognition of some specific objects. A single CCD camera and a group of ultrasonic transducers, which are responsible for activating the camera whenever the robot gets closer than 1m to any obstacle, compose the system. Although being a very simple and cheap one, this system allows recognizing a set of meaningful objects present in the robot workspace, even when more than one object is present in the scene, like it is shown in the examples presented.

A New Method of Mobile Robot Navigation: Shortest Null Space

In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

Dynamic Obstacle Avoidance by Distributed Algorithm based on Reinforcement Learning (RESEARCH NOTE)

In this paper we focus on the application of reinforcement learning to obstacle avoidance in dynamic Environments in wireless sensor networks. A distributed algorithm based on reinforcement learning is developed for sensor networks to guide mobile robot through the dynamic obstacles. The sensor network models the danger of the area under coverage as obstacles, and has the property of adoption o...
