Recap of day 3 from the Transdec!

Jul 16, 2011
by SubjuGator
competition, first place, static judging
Comments are off

We awoke early in order to get an early practice in before our preliminary round competition run at 9:30am. We left the hotel at 6:15am to reserve a spot on the practice side of the pond at about 8:20am. Our official weigh-in was at 46.5kg (102.5 lbs), well above the weight that we were told on day one, but about what we expected.

After a pretty good practice run, we had a disastrous preliminary run! On our first pass the sub went straight through the gate, but at a pace of less than half of our normal speed. We stopped the run and after some small modifications of code, we restarted our run. The sub did not move! After a few more tries we realized that we needed to cancel our runs and go back to our tent to analyze our problems in more depth. We found an error that should not have occurred, but somehow did. We had two mission planners running simultaneously! We lost our first chance to qualify for the finals, but with the knowledge that we will have another chance tomorrow (Saturday), we did not lose our confidence.

Our afternoon practice went very well. We went straight through the gate and hit the buoys and worked some on going over the hedges and towards the pinger. We will work into the night to get all the task solid that do not require actuation. We will attempt to run the entire course, including the actuation tasks, in the finals.

Wish us luck tomorrow and of course … Go Gators!

About Us

The Machine Intelligence Laboratory (MIL) provides a synergistic environment dedicated to the study and development of intelligent, autonomous robots. The faculty and students associated with the laboratory conduct research in the theory and realization of machine intelligence covering topics such as machine learning, real-time computer vision, statistical modeling, robot kinematics, autonomous vehicles, teleoperation and human interfaces, robot and nonlinear control, computational intelligence, neural networks, and general robotics. Applications of MIL research include autonomous underwater vehicles (AUVs), autonomous water surface vehicles (ASVs), autonomous land vehicles, autonomous air vehicles (AAVs including quadcopters and micro air vehicles, MAVs) , swarm robots, humanoid robots, and autonomous household robots.

MIL’s SubjuGator is the three time champion autonomous submarine of the RoboSub AUVSI/ONR underwater competition (2005-2007), and placed in the top 3 in eleven of the 21 years of the competition (including second place in 2012, 2013 and 2014). MIL’s NaviGator AMS, is the defending champion in the Maritime RobotX Challenge (from our victory in our only entry in this biennial competition in 2016). In 2013, MIL participated for the first time in the RoboBoat AUVSI/ONR water surface vechicle competition with our PropaGator robot boat; we won! In 2014, we earned second place in the RoboBoat competition. We also won the static division of the 2011 ION Robot Lawnmower competition with MIL’s InstiGator robot lawnmower.
