The Association for Unmanned Vehicle Systems International
(AUVSI) is the world's largest non-profit organization devoted
exclusively to advancing the unmanned systems community. AUVSI,
with members from government organizations, industry and
academia, is committed to fostering, developing, and promoting
unmanned systems and related technologies.

This is a
competition hosted by
AUVSI and the Office of Naval Research
(ONR). The competition involved Autonomous Underwater
Vehicles (AUVs) developed by teams comprising mainly of
students with the purpose of completing certain tasks as
given in order, or otherwise.
It is held every year at the
Space and Naval Warfare
Systems Centre, TRANSDEC
Facility, San Diego, California, USA .

Considering the tasks of the competition, the team decided
against a single high level control instead of going for
distributed computing which gives better performance and
reliability in case of failure. The software is event based,
which triggers for sensorial input confining to tasks
parameters.
In the start of the mission, the vehicle shall descend to a
pre-programmed depth and hold its position. It shall then
conduct a circular scan to ascertain the gate location. Having
passed the gate, it shall proceed to scan for the red light. On
determining its position, it will proceed with the docking
(dislodging the buoy) following which it shall proceed along the
dashed line. It shall stop at the first bin for dropping the
marker while the second bin will be approached with a
predetermined velocity to dislodge the second buoy, after which
the marker will then be dropped.
The last part will involve homing in on an acoustic pinger by
way of triangulation. Hovering above the pinger, the vehicle
will attempt to capture the 'X' as it moves upwards towards the
octagons. Finally, it shall surface in the middle of the
required octagon.
