International Aerial Robotics Competition
The Robotics Competition of the Millennium
For the past seven years collegiate teams,
with the backing of industry and government have fielded autonomous
flying robots in an attempt to perform missions that required robotic
behaviors never before exhibited in a flying machine. In 1990,
the term "Aerial Robotics" was coined by competition creator Robert
Michelson to describe a new class of small highly intelligent flying
machines. The successive years of competition saw these aerial
robots grow in their capabilities from vehicles that could at first
barely maintain themselves in the air, to the most recent automatons
which are self-stable, self-navigating, and able to interact with
their environment-- especially, objects on the ground.
The primary goal of the competition has been
to provide a reason for the state-of-the art in aerial robotics
to move forward. Challenges set before the international collegiate
community have been geared to produce advances in the state-of-the-art
at an evermore aggressive pace. The initial mission to move a metallic
disc from one side of an arena to another with a completely autonomous
flying robot was seen by many as almost impossible. Those lacking
vision labeled the competition as a "crash and burn" event or a
source of demoralization for the students, while pundits in the
media predicted that it would be the year AD 2000 before that mission
was achievable.
Just as an infant stumbles in its attempts
to learn to walk, the college teams continued to improve their
entries over the next two years when the competition saw its first
autonomous takeoff, flight, and landing by a team from the Georgia
Institute of Technology. Three years later in 1995 a team from
Stanford University was able to acquire a single disk and move
it from one side of the arena to the other in a fully autonomous
flight-- half a decade earlier than some media predictions.
The competition mission was then toughened
and made a bit less abstract by requiring teams to search for a
toxic waste dump, map the location of partially-buried randomly-oriented
toxic waste drums, identify the contents of each drum from the
hazard labels found somewhere on the outside of each drum, and
bring a sample back from one of the drums. Again the pundits threw
up their hands and said that this was nearly impossible for a fully
autonomous flying machine, particularly one made by university
students.
That year, a team from the Massachusetts Institute
of Technology and Boston University, with backing from Draper Labs,
created a small fully autonomous flying robot that repeatedly and
correctly mapped the location of all five of the toxic waste drums
while correctly identifying the contents of two from the air, thereby
completing approximately seventy five percent of the mission. In
1997 the mission was left the same, but some of the structure was
removed to make it more realistic. The number of drums became an
unknown a priori. In addition to radioactive and biohazardous toxic
waste, a third category of explosive material was included and
the retrieval of the sample became mandatory.
In a triumph of technology, a team from Carnegie
Mellon University attacked the mission with a large helicopter-based
robot and was able to identify the location of all drums as well
as read the labels on each correctly. Their aerial robot came within
centimeters of acquiring the sample on several runs. All of this
was achieved from a fully-autonomous aerial robot that stayed aloft
for more than twenty minutes per run and modified its actions in
real-time based on what it learned about its environment.
As realistic as the mission of 1997 was, it
was still highly structured. The arena was limited in extent, the
number of target drum types was only three, the exact number of
drums (though unknown) was guaranteed to be less than eleven. Still,
the primary goal of the competition has been served in that the
state-of-the-art has advanced by providing a reason and benchmarks
to entice its move forward.
The International Aerial Robotics Competition
has grown in stature over the past seven years to the point that
corporations now seek teams to sponsor, major governmental agencies
such as the U.S. Department of Energy and the U.S. Department of
Defence support the event with personnel, judges, and funding for
logistics. Top venues such as Walt Disney World seek to have the
event hosted at their locations. The students who participate and
develop entries that perform well are likewise recognized by industry
and government observers as the best of the next generation of
young engineering and computer scientists to hire.
Since the level of technical performance demonstrated
to date has increased exponentially, the time has come to move
the International Aerial Robotics Competition mission to a higher
level of realism and attendant difficulty. The following paragraphs
define the mission in general terms to allow potential entrants
to plan and begin development.
International Aerial Robotics Competition
The Robotics Competition of the Millennium
The Earth is a violent planet regularly wreaking
havoc upon mankind in the form of natural disasters. The nature
of some groups of individuals is similarly violent and often mimics
the mass destruction occasioned by natural forces. Between what
befalls mankind apart from his control, and that which befalls
him by his own hand, there is a seeming endless parade of disasters
from which mankind must extricate itself. Those seeking prophecy
in ancient literature have often interpreted the utterances of
Nostradamus as portending catastrophe with the coming of the new
millennium. In the wake of such upheavals, mankind would require
massive assistance in dealing with multiple emergencies. Unmanned
Systems exist to remove mankind from dull, dirty, and dangerous
tasks or to allow the conduct of missions with duration beyond
a life span.
The International Aerial Robotics Competition
will celebrate its tenth anniversary at the dawning of the new
millennium. Accordingly, the mission definition will involve the
use of autonomous robots in a human search-and-rescue role during
and immediately after a catastrophe of major proportions in which
an urban area has been decimated by earthquake, tsunami, and wind.
The ultimate cause could be volcanism, the impact of an erratic
near-Earth orbiting asteroid, or multiple nuclear explosions triggered
by terrorists in an underground storage bunker. Information is
unavailable-- all you and your design team know is that your research
facility has somehow survived the night along with its complement
of autonomous robots. Ensuing chemical fires rage amid the wreckage
of buildings. Toxic clouds of smoke choke the skies and obscure
the view. Your sensors indicate that low level radiation is present.
There are other survivors out there who are
injured and must be found before they die. Fire fighters in hazmat
suits and respirators are attempting to find survivors and extract
them to a safer location. Your autonomous robots have to be reprogrammed
to search for living humans on the ground and either find and report
their location to the human rescue team who will attempt to save
them, or if possible your robots may attempt to extricate the survivors.
The Arena: A
disaster scene will be replicated with highly unstructured and
unpredictable events. Your autonomous robot(s) will have to be
robust enough to operate in a realistic environment that contains
wreckage, fire, smoke and aerosols, acoustic shock waves, motion
on the ground and in the air, as well as unbriefed obstacles.
Your targets are injured humans on the ground
that are simulated by animatronic synthetics capable of limited
limb motion and sound. All survivors will be incapacitated and
unable to move to safety under their own power. These synthetics
will be programmed to expire at predetermined intervals unknown
to the team. The number of injured humans and their location relative
to the disaster scene is unknown.
Alternate targets of interest will represent
potential hazards to rescue teams entering the area. These lower
priority targets will include items such as drums of hazardous
material, some potentially explosive, amid others which are inert.
Scoring: An
actual human search-and-rescue team will be given one chance to
enter the area to rescue as many injured people as possible. Their
time in the area will be limited due to the simulated radiation
hazard. They will be encumbered with hazmat suits and respirators
and will have to deal with fire threats and smoke obscuration.
The human search-and-rescue team will set the baseline performance
comparison to which the autonomous robots will be judged.
Teams will be able to field one or more fully
autonomous robots which may work simultaneously and synergistically
to identify and map targets of interest. Ground robots may be deployed
from the aerial robots, or may be launched from the starting point
to work in concert with the aerial robots.
Points will be accrued for successfully performing
tasks that would normally have to be done by human search-and-rescue
teams or fire fighters. These will include, but are not at this
time limited to: identifying the location of survivors, identifying
the location of dead bodies, identifying hazards to be avoided,
and identifying potential hazards. Given enough time (less than
one hour), all survivors will become dead bodies. More points will
be allotted for identifying the living. In addition, actions taken
by the autonomous robots to improve the situation will accrue points.
This will include, but not at this time be limited to: extinguishing
fires, extracting survivors, providing life-support equipment to
survivors, laying down paths/markers/lines through wreckage to
survivors or to other locations requiring the attention of emergency
personnel.
Administration: Multiple
robots may be entered from a given University, but there will only
be one official team from each school.
Each entry must involve at least one autonomous
aerial robot, however autonomous ground robots are also allowed.
If multiple autonomous robots are offered as part of a single entry,
they must communicate with one another as a distributed sensor
and intelligence rather than independent entities.
There will be an entry fee that is partially
refundable upon successfully meeting certain mission criteria.
Various "qualifiers" must be passed in order
to become a finalist in the Millennial event. These qualifiers
will occur in 1998 and 1999. The qualifiers will allow entries
to demonstrate behaviors necessary to successfully compete in the
Millennial event. Therefore this will be a three year effort and
some participants may not be able to see event to completion. For
this reason, the student eligibility requirements allow certified
team graduates to remain involved with a team.
As in 1998, the location for the 1999 and
2000 qualifiers, and the competition in AD 2000 will be the U.S.
Department of Energy's Hazardous Material Management and Emergency
Response (HAMMER) facility near the Hanford nuclear plant in Washington
State.
Thirty thousand dollars (or more) will be
awarded to the winner(s) of the competition (this amount will grow
as additional benefactors join AUVSI in sponsoring the Millennial
Event). Small monetary awards for successfully passing the annual
qualifying tests leading to eligibility in the Millennial event
may also be awarded.
How to Get Started: The
first qualifier in 1998 involved demonstration of autonomous flight
over a large area (five acres or more) containing briefed obstacles.
In 1999, aerial robots should be able to locate
at least one of several items that will be encountered in the Millennial
event. This will range from partially-buried, randomly-oriented
drums of potentially explosive materials (amid debris and drums
of inert materials), the location of fire sources, simulated dead
bodies, or a simulated injured survivor on the ground that is signalling
for help with a "waving arm motion". The more items correctly identified,
the higher the qualifying score. The 1999 qualifier will require
interaction with the target items, but still in a semi-structured
environment. The inclusion and demonstration of autonomous ground
robots will be possible in 1999.
During the various qualifiers, all entries
must amass at least 2000 points in order to progress toward finalist
status and admission into the Millennial event in AD 2000. At the
organizer's discretion, a qualifier may also be held immediately
prior to the Millennial Event in AD 2000 for those teams having
earned the majority of their 2000 points in either the 1998 or
1999 qualifiers, but which can credibly be expected to meet the
requirement given one more chance (this could also provide relief
for documented hardship cases).
