Underwater Robot Competition Makes a Splash
Regardless of the distinct scent of chlorine and roped-off lanes on the Eppley Recreation Heart, the scholar groups huddled alongside the perimeters of the pool aren’t right here for any peculiar swim meet.
As a substitute, a bundle of wires, propellers and sensors glides underneath the water, however doesn’t fairly make it to the hovering gate in entrance of it or the opposite surrounding obstacles. A diver in flippers and a snorkel has to seize it and hook it as much as a small crane to floor.
It’s all a part of the 25th working of RoboSub, a global competitors that challenges pupil groups to design and construct robotic submarines—also called autonomous underwater automobiles (AUVs)—that may full a sequence of duties whereas submerged. Robotics @ Maryland, the College of Maryland’s workforce, is amongst 39 teams collaborating by means of Tuesday. After happening for a number of years in San Diego after which shifting on-line throughout COVID-19, the annual occasion is being held for the primary time at UMD.
“It’s been very thrilling to host,” stated Dillon Capalongo ’24, Robotics @ Maryland’s mechanical lead. “Everybody who’s been serving to volunteer has been supporting us, saying, ‘Go Terps! That is our college!’”
UMD has positioned extremely within the competitors previously, together with successful it in 2008. This yr marks the workforce’s RoboSub return for the reason that pandemic started, and its robotic, Qubo, is taking the plunge.
Qubo, which debuted within the 2017 competitors, is smaller, extra cell and extra modular than its predecessor, Tortuga IV, Capalongo stated. Tweaks over time have additional streamlined the bot, with the workforce—round 30 Terps from a wide range of majors—growing and training with it within the Impartial Buoyancy Analysis Facility, the one such tank on the planet on a school campus.

The Terps have loved their home-field benefit, Capalongo stated. Earlier than delving into the qualifying rounds, which wrap up Saturday, they hopped over to the tank on Friday to re-solder and take a look at a free tether connection.
To advance to the semifinals, which start Sunday, AUVs should acknowledge and cross by means of a gate within the water. Subsequent, groups should showcase their robots’ abilities by means of a sequence of duties, together with recognizing pictures on buoys, dropping markers into bins and firing torpedoes by means of a goal. (This yr’s contest is Roaring Twenties-themed, so bootlegger and G-man icons run rampant all through the underwater course.)
“The principle factor is that the second your robotic surfaces, the run is over,” stated Rainier Hood, Robotics @ Maryland electrical lead. “It’s a must to ensure you’re not breaching in the midst of your run.” And human creators can’t intrude with the bots as soon as they’re within the water.
Groups—which embody powerhouses like Carnegie Mellon College, the College of Alberta and the Nationwide College of Singapore—huddled round laptops, carted round tools and examined their tech at Eppley on Friday. Bringing collectively budding engineers from around the globe in such competitions is “improbable from the standpoint of engineering schooling,” stated Dave Akin, Robotics @ Maryland workforce advisor and affiliate professor of aerospace engineering. The hands-on expertise mimics real-world methods used for underwater exploration, seafloor mapping and extra.
“Consider it this manner,” he tells college students. “When the time comes that you’re interviewing in your first job, you’re not going to be caught saying, ‘Effectively, I took this course and I took that course.’ You possibly can say, ‘I constructed a robotic and competed with it underwater.’”
