Mobile robots in real-life settings would benefit from being able to localize and track sound sources. Such a capability can help localizing a person or an interesting event in the environment , and also provides enhanced processing for other capabilities such as speech recognition. To give this capability to a robot, the challenge is not only to localize(More)
—Unpredictability and complexity of social interactions are important challenges for a child with low-functioning autism. The objective of this research is to study how a mobile robot can, by appearing more predictable, appealing and simple than a human being, facilitate reciprocal interaction such as imitative play. By conducting an exploratory study with(More)
For large-scale and long-term simultaneous localization and mapping (SLAM), a robot has to deal with unknown initial positioning caused by either the kidnapped robot problem or multi-session mapping. This paper addresses these problems by tying the SLAM system with a global loop closure detection approach, which intrinsically handles these situations.(More)
In appearance-based localization and mapping, loop-closure detection is the process used to determinate if the current observation comes from a previously visited location or a new one. As the size of the internal map increases, so does the time required to compare new observations with all stored locations, eventually limiting online processing. This paper(More)
ROBUS (ROBot University of Sherbrooke) is an autonomous mobile robot designed to facilitate interdisciplinary engineering design in Electrical Engineering (EE) and Computer Engineering (CE). Its primary purpose is to serve as an integrated platform for a project called INGÉNIUS that introduces electrical and computer engineering simultaneously to a large(More)
Planning with actions concurrency under resources and time uncertainty has been recognized as a challenging and interesting problem. Most current approaches rely on a discrete model to represent resources and time, which contributes to the combinato-rial explosion of the search space when dealing with both actions concurrency and resources and time(More)
The hearing sense on a mobile robot is impor. tan1 because it is omnidirectional and it does not require direct tine-of-sight with the sound source. Such capabilities can nicely complement vision to help localize a person or an interesting event in the environment. To do so the robot auditory system must he able to work in noisy, unknown and diverse(More)
We propose a system that gives a mobile robot the ability to separate simultaneous sound sources. A microphone array is used along with a real-time dedicated implementation of geometric source separation and a post-filter that gives us a further reduction of interferences from other sources. We present results and comparisons for separation of multiple(More)
