Very cool story, while I disagree with the idea of scholarship set asides for undocumented teens, the idea of a scholarship fund set up for these kids, if the US isn't deporting them, well then...

How four underdogs from the mean streets of Phoenix took on the best from M.I.T. in the national underwater bot championship.
...
Across campus, in a second-floor windowless room, four students huddle around an odd, 3-foot-tall frame constructed of PVC pipe. They have equipped it with propellers, cameras, lights, a laser, depth detectors, pumps, an underwater microphone, and an articulated pincer. At the top sits a black, waterproof briefcase containing a nest of hacked processors, minuscule fans, and LEDs. It's a cheap but astoundingly functional underwater robot capable of recording sonar pings and retrieving objects 50 feet below the surface. The four teenagers who built it are all undocumented Mexican immigrants who came to this country through tunnels or hidden in the backseats of cars. They live in sheds and rooms without electricity. But over three days last summer, these kids from the desert proved they are among the smartest young underwater engineers in the country.
...
Just getting them to the Santa Barbara contest in June with a robot would be an accomplishment, Cameron thought. He and Ledge had to gather a group of students who, in four months, could raise money, build a robot, and learn how to pilot it. They had no idea they were about to assemble the perfect team.
"We should use glass syntactic flotation foam," Cristian said excitedly at that first meeting. "It's got a really high compressive strength."
Cameron and Ledge looked at each other. Now they had their genius.
Oscar Vazquez was a born leader. A senior, he'd been in ROTC since ninth grade and was planning on a career in the military. But when he called to schedule a recruitment meeting at the end of his junior year, the officer in charge told him he was ineligible for military service. Because he was undocumented - his parents had brought him to the US from Mexico when he was 12 - he couldn't join, wouldn't get any scholarships, and had to start figuring out what else to do with his life. Oscar felt aimless until he heard about the robot club from Ledge, who was teaching his senior biology seminar. Maybe, he thought, engineering could offer him a future.
...
Oscar began by explaining that his high school team was taking on college students from around the US. He introduced his teammates: Cristian, the brainiac; Lorenzo, the vato loco who had a surprising aptitude for mechanics; and 18-year-old Luis Aranda, the fourth member of the crew. At 5'10" and 250 pounds, Luis looked like Chief from One Flew Over the Cuckoo's Nest. He was the tether man, responsible for the pickup and release of what would be a 100-pound robot.
...
Oscar helped persuade a handful of local businesses to donate money to the team. They raised a total of about $800. Now it was up to Cristian and Lorenzo to figure out what to do with the newfound resources. They began by sending Luis to Home Depot to buy PVC pipe. Despite the donations, they were still on a tight budget. Cristian would have to keep dreaming about glass syntactic flotation foam; PVC pipe was the best they could afford.
But PVC had benefits. The air inside the pipe would create buoyancy as well as provide a waterproof housing for wiring. Cristian calculated the volume of air inside the pipes and realized immediately that they'd need ballast. He proposed housing the battery system on board, in a heavy waterproof case.
It was a bold idea. If they didn't have to run a power line down to the bot, their tether could be much thinner, making the bot more mobile. Since the competition required that their bot run through a series of seven exploration tasks - from taking depth measurements to locating and retrieving acoustic pingers - mobility was key. Most of the other teams wouldn't even consider putting their power supplies in the water. A leak could take the whole system down. But if they couldn't figure out how to waterproof their case, Cristian argued, then they shouldn't be in an underwater contest.
While other teams machined and welded metal frames, the guys broke out the rubber glue and began assembling the PVC pipe. They did the whole thing in one night, got high on the pungent fumes, and dubbed their new creation Stinky. Lorenzo painted it garish shades of blue, red, and yellow to designate the functionality of specific pipes. Every inch of PVC had a clear purpose. It was the type of machine only an engineer would describe as beautiful.
...
Even though Lorenzo had never heard of MIT, the team from Cambridge scared him, too. There were 12 of them - six ocean-engineering students, four mechanical engineers, and two computer science majors. Their robot was small, densely packed, and had a large ExxonMobil sticker emblazoned on the side. The largest corporation in the US had kicked in $5,000. Other donations brought the MIT team's total budget to $11,000.
As Luis hoisted Stinky to the edge of the practice side of the pool, Cristian heard repressed snickering. It didn't give him a good feeling. He was proud of his robot, but he could see that it looked like a Geo Metro compared with the Lexuses and BMWs around the pool. He had thought that Lorenzo's paint job was nice. Now it just looked clownish.
Things got worse when Luis lowered Stinky into the water. They noticed that the controls worked only intermittently. When they brought Stinky back onto the pool deck, there were a few drops of water in the waterproof briefcase that housed the control system. The case must have warped on the trip from Arizona in the back of Ledge's truck. If the water had touched any of the controls, the system would have shorted out and simply stopped working. Cristian knew that they were faced with two serious problems: bad wiring and a leak.
...
An image from television flashed through Lorenzo's mind. "Absorbent?" he asked. "Like a tampon?"
The Ralph's grocery store near the UCSB campus is done up to look like a hacienda, complete with a red tile roof, glaringly white walls, and freshly planted palms. The guys dropped Lorenzo off in front. It was his bright idea, after all. He wandered past the organic produce section, trying to build up his courage. He passed an elderly lady examining eggplant - he was too embarrassed to ask her. Next, he saw a young woman in jeans shopping for shampoo.
"Excuse me, madam," he began. He wasn't used to approaching women, let alone well-dressed white women. He saw apprehension flash across her face. Maybe she thought he was trying to sell magazines or candy bars, but he steeled himself. He explained that he was building a robot for an underwater contest, and it was leaking. He wanted to soak up the water with tampons but didn't know which ones to buy. "Could you help me buy the most best tampons?"
The woman broke into a big smile and led him to feminine hygiene. She handed him a box of O.B. ultra-absorbency. "These don't have an applicator, so they'll be easier to fit inside your robot," she said. He stared at the ground, mumbled his thanks, and headed quickly for the checkout.
"I hope you win," she called out, laughing.
...
When Luis lowered Stinky into the water for their run, Lorenzo prayed to the Virgin Mary. He prayed that the tampons would work but then wondered if the Virgin got her period and whether it was appropriate for him to be praying to her about tampons. He tried to think of a different saint to pray to but couldn't come up with an appropriate one.

Tom Swean was the gruff 58-year-old head of the Navy's Ocean Engineering and Marine Systems program. He developed million-dollar autonomous underwater robots for the SEALs at the Office of Naval Research. He was not used to dealing with Mexican-American teenagers sporting gold chains, fake diamond rings, and patchy, adolescent mustaches.
The Carl Hayden team stood nervously in front of him. He stared sullenly at them. This was the engineering review - professionals in underwater engineering evaluated all the ROVs, scored each team's technical documentation, and grilled students about their designs. The results counted for more than half of the total possible points in the contest.
"How'd you make the laser range finder work?" Swean growled. MIT had admitted earlier that a laser would have been the most accurate way to measure distance underwater, but they'd concluded that it would have been difficult to implement.
"We used a helium neon laser, captured its phase shift with a photo sensor, and manually corrected by 30 percent to account for the index of refraction," Cristian answered rapidly, keyed up on adrenaline. Cameron had peppered them with questions on the drive to Santa Barbara, and Cristian was ready.
Swean raised a bushy, graying eyebrow. He asked about motor speed, and Lorenzo sketched out their combination of controllers and spike relays. Oscar answered the question about signal interference in the tether by describing how they'd experimented with a 15-meter cable before jumping up to one that was 33 meters.
"You're very comfortable with the metric system," Swean observed.
"I grew up in Mexico, sir," Oscar said.
Swean nodded. He eyed their rudimentary flip chart.
"Why don't you have a PowerPoint display?" he asked.
"PowerPoint is a distraction," Cristian replied. "People use it when they don't know what to say."
"And you know what to say?"
"Yes, sir."
...
"Can we go to Hooters if we win?" Lorenzo asked.
"Sure," Ledge said with a dismissive laugh. "And Dr. Cameron and I will retire, too."
...
The first award was a surprise: a judge's special prize that wasn't listed in the program. Bryce Merrill, the bearded, middle-aged recruiting manager for Oceaneering International, an industrial ROV design firm, was the announcer. He explained that the judges created this spontaneously to honor special achievement. He stood behind a podium on the temporary stage and glanced down at his notes. The contestants sat crowded around a dozen tables. Carl Hayden High School, he said, was that special team.
The guys trotted up to the stage, forcing smiles. It seemed obvious that this was a condescending pat on the back, as if to say, "A for effort!" They didn't want to be "special" - they wanted third. It signaled to them that they'd missed it.
They returned to their seats, and Cameron and Ledge shook their hands.
"Good job, guys," Ledge said, trying to sound pleased. "You did well. They probably gave you that for the tampon."
After a few small prizes were handed out (Terrific Tether Management, Perfect Pickup Tool), Merrill moved on to the final awards: Design Elegance, Technical Report, and Overall Winner. The MIT students shifted in their seats and stretched their legs. While they had been forced to skip the fluid sampling, they had completed more underwater tasks overall than Carl Hayden or Cape Fear. The Cape Fear team sat across the room, fidgeted with their napkins, and tried not to look nervous. The students from Monterey Peninsula College looked straight ahead. They placed fourth behind Carl Hayden in the underwater trials. They were the most likely third-place finishers. The guys from Phoenix glanced back at the buffet table and wondered if they could get more cake before the ceremony ended.
Then Merrill leaned into the microphone and said that the ROV named Stinky had captured the design award.
"What did he just say?" Lorenzo asked.
"Oh my God!" Ledge shouted. "Stand up!"
Before they could sit down again, Merrill told them that they had won the technical writing award.
"Us illiterate people from the desert?" Lorenzo thought. He looked at Cristian, who had been responsible for a large part of the writing. Cristian was beaming. To his analytical mind, there was no possibility that his team - a bunch of ESL students - could produce a better written report than kids from one of the country's top engineering schools.
They had just won two of the most important awards. All that was left was the grand prize. Cristian quickly calculated the probability of winning but couldn't believe what he was coming up with. Ledge leaned across the table and grabbed Lorenzo's shirt. "Lorenzo, if what I think is about to happen does happen, I do not, under any circumstances, want to hear you say the word 'Hooters' onstage."
"And the overall winner for the Marine Technology ROV championship," Merrill continued, looking up at the crowd, "goes to Carl Hayden High School of Phoenix, Arizona!"
Lorenzo threw his arms into the air, looked at Ledge, and silently mouthed the word "Hooters."
