Challenge is an Office of
Naval Research Sponsored
STEM program, in which
teams of high school stu-
dents design and build
robotic vehicles and pay-
loads. The systems are
then used to compete in
challenges that mimic mis-
sions encountered by the
military, national security agencies and first responders.
The background image is of a remote control airplane
used for the Air Challenge. The students were present-
ed with the issue of forest fires that require aerial water
drops. This Challenge provided the students with an op-
portunity to build a payload that could one day perform
these types of task on an unmanned aircraft.
The image in the top inset is a remote control heli-
copter used for the Land and Air Combined Challenge.
The students were presented with the scenario of people
trapped in a city building after an earthquake. The task
was to build a ground robot and a payload (for the heli-
copter) to deliver supplies to the trapped victims.
The images in the bottom two inset are ground robots
designed by students for the Land Challenge. In this sce-
nario it was assumed that people were trapped in a city
building after an earthquake. The task was to find, pick
up, carry and deposit objects in a drop box.
For more information about the Sea, Air and Land
Challenge read the interview on page 432.
