Effective robot navigation in the presence of humans is hard. Not only do human obstacles move, they react to the movements of the robot according to instinct and social rules. In order to efficiently navigate around each other, both the robot and the human must move in a way that takes the other into account. Failure to do so can lead to a lowering of the(More)
Many navigation systems, including the ubiquitous ROS navigation stack, perform path-planning on a single costmap, in which the majority of information is stored in a single grid. This approach is quite successful at generating collision-free paths of minimal length, but it can struggle in dynamic, people-filled environments when the values in the costmap(More)
Human-Robot Interaction literature frequently uses Gaus-sian distributions within navigation costmaps to model proxemic constraints around humans. While it has proven to be effective in several cases, this approach is often hard to tune to get the desired behavior, often because of unforeseen interactions between different elements in the costmap. There is,(More)
— Given the difficulty of social human-robot interaction (HRI), finding an appropriate conceptual model, as well as a useful venue to test the model, is key. While most work in social HRI draws insight and inspiration from the field of social psychology, this paper explores the philosophical backing and benefits of using ideas from theatre to frame social(More)
Since its official introduction in 2012, the Robot Web Tools project has grown tremendously as an open-source community, enabling new levels of interoperability and portability across heterogeneous robot systems, devices, and front-end user interfaces. At the heart of Robot Web Tools is the rosbridge protocol as a general means for messaging ROS topics in a(More)
MOTIVATION The most accurate way to determine the intron-exon structures in a genome is to align spliced cDNA sequences to the genome. Thus, cDNA-to-genome alignment programs are a key component of most annotation pipelines. The scoring system used to choose the best alignment is a primary determinant of alignment accuracy, while heuristics that prevent(More)
In social interactions, the appropriate timing of physical actions is of vital importance. Otherwise appropriate actions performed at the wrong time can completely alter their perceived meaning. In this paper, we propose an approach to developing a physical vocabulary for human-robot interaction that uses trained actors as models of appropriate timing and(More)
