With the increasing need for multi-robot exploring unknown region in a challenging environment, efficient collaborative exploration strategies are needed achieving such feat. A frontier-based Rapidly-Exploring Random Tree (RRT) can be deployed to explore an environment. However, its' greedy behavior causes multiple robots with highest revenue, which leads massive overlapping process. To address...
Mobile robot navigation is one of the basic problems in robotics. In this paper, a new approach is proposed for autonomous mobile robot navigation in an unknown environment. The proposed approach is based on learning virtual parallel paths that propel the mobile robot toward the track using a multi-layer, feed-forward neural network. For training, a human operator navigates the mobile robot in ...
