In military scenarios, agents (i.e., troops of soldiers, convoys, and unmanned vehicles) may often have to traverse environments with only a limited intelligence about the locations of adversaries. We study a particular instance of this problem that we refer to as path clearance problem.This article presents a survey of our work on scalable and suitable for real-time use approaches to solving the...
Knowledge of the driving environment is essential for robotic vehicles to comply with traffic rules while autonomously traversing intersections. However, due to limited sensing coverage and continuous changes in driving conditions, rigidly-mounted sensors may not guarantee coverage of all regions of interest, all the time. Unobserved regions around intersections increase uncertainty in driving conditions...
Autonomous robots operating in human environments will need to automatically learn to perform new tasks without requiring the implementation of task-specific actions or time-consuming deliberative planning at run-time. In this work, we contribute a demonstration-based approach for teaching a robot task-specific planners involving complex sequential tasks with repetitions. Complexity of tasks results...
The path followed by a mobile robot while mapping an environment (i.e. an exploration trajectory) plays a large role in determining the efficiency of the mapping process and the accuracy of any resulting metric map of the environment. This paper examines some important aspects of path planning in this context: the trade-offs between the speed of the exploration process versus the accuracy of resulting...
Map building in unknown environment is the prerequisite to perform other tasks for the mobile robots. An effective approach based on the frontier points is proposed in this paper. Firstly, an adaptive clustering algorithm which integrates subtractive clustering and k-means clustering is introduced to partition the frontier points into different groups. Secondly, the centers of the groups serve as...
