title = {Player/Stage as Middleware for Ubiquitous Computing},
booktitle = {Proceedings of the 8th Annual Conference on Ubiquitous Computing
(Ubicomp 2006), Orange County California, September 17-21},
year = {2006},
abstract = {
The effective development and deployment of
comprehensive and heterogeneous ubiquitous computing
applications is hindered by the lack of a
comprehensive middleware infrastructure: interfaces
to sensors are company specific and sometimes even
product specific. Typically, these interfaces also
do not sustain the development of robust systems that
make use of sensor data fusion. In this paper, we
propose the use of Player/Stage, a middleware
commonly used as a defacto standard by the robotics
community, as the backbone of a heterogeneous
ubiquitous system. Player/Stage offers many features
needed in ubicomp, mostly because dealing with
uncertainty and many different sensor and actuator
systems has been a long term problem in robotics as
well. We emphasize they key features of the
Player/Stage project, and show how ubicomp devices
can be integrated into the system, as well as how
existing devices can be used. On top of that, we
present our sensor-enabled AwareKitchen environment
which makes use of automatic data analysis algorithms
integrated as drivers in the Player/Stage platform.
All our work is released as open source software
under the Player/Stage package, of which we are
active developers.

We propose Player/Stage, a well-known platform widely
used in robotics, as middleware for ubiquitous
computing. Player/Stage provides uniform interfaces
to sensors and actuators and allows the computational
matching of input and output. Player/Stage exactly
addresses the issues of dealing with heterogeneous
hardware but currently only with a focus towards
robotics. We show how to integrate ubiquitous
computing platforms into Player/Stage and propose
Player/Stage as middleware for ubiquitous computing
projects.},

system for football games that is used for the
automatic analysis of football games and reasoning
about multi-agent activity. The observation system
runs on video streams produced by cameras set up for
TV broadcasting. The observation system achieves
reliability and accuracy through various mechanisms
for adaptation, probabilistic estimation, and
exploiting domain constraints. It represents motions
compactly and segments them into classified ball
actions.}

abstract = {
One of the most notable and recognizable features of robot motion is the abrupt
transitions between actions in action sequences. In contrast, humans and animals
perform sequences of actions efficiently, and with seamless transitions between
subsequent actions. This smoothness is not a goal in itself, but a side-effect
of the evolutionary optimization of other performance measures.
In this paper, we argue that such jagged motion is an inevitable consequence of
the way human designers and planners reason about abstract actions. We then
present subgoal refinement, a procedure that optimizes action sequences. Subgoal
refinement determines action parameters that are not relevant to why the action
was selected, and optimizes these parameters with respect to expected execution
performance. This performance is computed using action models, which are learned
from observed experience. We integrate subgoal refinement in an existing
planning system, and demonstrate how requiring optimal performance causes smooth
motion in three robotic domains.

abstract = {Standardized middleware for autonomous robot
control has proven itself to enable faster
deployment of robots, to make robot control code
more interchangeable, and experiments easier to
replicate. Unfortunately, the support provided
by current middleware is in most cases limited
to what current robots do: navigation. However,
as we tackle more ambitious service robot
applications, more comprehensive middleware
support is needed. We increasingly need the
middleware to support ubiquitous sensing
infrastructures, robot manipulation tasks, and
cognitive capabilities. In this paper we
describe and discuss current extensions of the
Player/Stage/Gazebo (P/S/G) middleware, one of
the most widespread used robot middlewares, of
which we are active developers, that satisfy
these requirements.},
