This paper explores a newly developing direction of machine learning called''socially
embedded learning". In this research we have been building an office-conversant mobile …

In this paper, we propose a hierarchical approach to solving sensor planning for the global
localization of a mobile robot. Our system consists of two subsystems: a lower layer and a …

Our Jijo-2 robot, whose purpose is to provide office services, such as answering queries
about people's location, route guidance, and delivery tasks, is expected to conduct natural …

Graphics Processing Units (GPUs) have recently emerged as a new platform for high
performance, general-purpose computing. Because current GPUs employ deep …

Multimodality for interaction tends to be considered as use of di erent physical
communication channels for face-to-face interaction. But our usual communication is indeed …

ABSTRACT A spoken dialog interface of a mobile office robot is described. To realize robust
speech recognition in noisy office environments, a microphone array system and a …

This paper reports on our work on the spoken dialogue interface to Jijo-2, an autonomous
mobile office robot. We propose an attentional state model for office robot dialogue based on …

This paper presents a mobile robot planning approach for solving the problem of indoor
cleaning tasks. In general, the robot must find its pose first and only then move to the final …

A map in mobile robotics plays an important role. The mobile robot is vested with a sense of
geographical understanding by such a knowledge base for its intelligent behavior. This …

This paper proposes a method of removing ambiguities in robot tasks by a multimodal
human-robot interface consisting of verbal and nonverbal communication. Such ambiguities …
