Formula SAE Racing Team Takes Autocross Again!

S&T's Formula SAE team has won its second straight autocross race in world-class competition. They are in California as part of their three-phased attack on the SAE racing world, following a second place finish in Virginia and 8th at the Michigan world championships. We don't yet have any firm results on acceleration, skid pad, braking or design events, but we'll get them to you as soon as we know.

2008 has been a tremendous turn-around for S&T's quickest and fastest design team (well, if you don't count AAVG's Mach 1.5 missile, but that is unmanned). Last year they didn't finish many races, and this year the Miners have been top-of-the-heap all the way.

This is more than just racing, it is about experiential learning. Like any design and manufacturing firm, you develop, build and test, over and over, until you are sure things will work reliably. Only then can you be sure the product is ready for market. In the past few years FSAE had developed a sophisticated but risky dry-sump lubrication system that would allow them to lower the car's center of gravity resulting in better speed and handling, an "edge" would help them outclass the competition. Years of work and refinement couldn't quite ensure reliability (as last year's race attests), so the '08 Miners returned to proven systems, simplified the car, and improved team communication, and Voila! Top-tier results all the way.

What We Did On Our Summer Vacation, Part Deux......

Summer vacation is a great time to head to destination spots such as Six Flags-Over-The-City-Nearest-You, where you can twist your stomach in a weightless knot on super-sophisticated rollercoasters...........and pay big bucks for the privilege.
Now, if you are a student at Missouri S&T you can go weightless for as long as possible while still remaining in earth's atmosphere, and all for FREE!. Think we're kidding? Well, just look at this!
MIS 081.jpg
Miners In Space (MIS) is a S&T multi-disciplinary student research team that is nearly out of this world. They work all year to plan and build experiments that operate in zero-gravity conditions, i.e. outer space. Since the waiting list for extra-terrestrial launch vehicles is years and mega-millions of dollars away, the next
MIS group1.jpg
best thing is NASA's research parabola jet, better know as the "vomit comet*". This aircraft repeatedly climbs and then dives to earth at the precise speed at which its cargo, both human and non-carbon based, float about the cabin as if in space; a free-form rollercoaster if you will. Just imagine, up and down, up and down, over and over again until your complexion turns green.
MIS 082.jpg
MIS has two design groups that conduct cutting-edge research on zero-gravity manufacturing and satellite navigation systems that even NASA and other countries with space experience haven't attempted. The team just returned from NASA's Johnson Space Center where Tonya Sanders, Adam Hoefer, Chad Stovall and Ryan Pahl worked on thruster systems that use gimble-mounted jets to steer satellites and other spacecraft. These fiery control thrusters have been used on rockets since World War II, but MIS have developed prototype COLD jet thrusters using less-volatile compressed gas, and the air-bearing platform necessary to measure the thrusters' effect. When the thruster control programs failed just before the flight they revamped the project in just two hours to concentrate on the friction-free platform's feasibility.
MIS 087.jpg
Michelle Rader and Caleb Baumgart "own" the zero-G welder aimed at future space-based manufacturing operations. Their project made both control welds at level flight and one weightless weld during a dive. MIS Caleb sitting 2.jpg
Before the Miners' second flight they adjusted voltage, heat, and wire-feed speeds and managed several more zero-G welds, as well as both lunar (1/6th-G) and martian (1/3rd-G) welds. Michelle says it was more reliable than past attempts, but was still not what they hoped for. They did gain enough information to determine the necessary speed, power and standards for repeatable manufacturing when men return to the moon or venture to Mars, but we are betting Michelle or Tonya will be there first, likely as mission commanders.
MIS sky view.jpg
NASA's education program pays for these flights, which cost $13,000 per hour, the kind of cash that will get your entire high school into Six Flags for a day. Each school, of which several flew together, goes through a grueling year-long review process to qualify for these research flights, and this trip was S&T's third flight series over the past few years. Those successful teams are assigned a NASA mentor who helps each team be flight-ready. S&T's guardian angel, Tamara George, was amazing in her support of the Miners and is typical of NASA folks who really WANT these teams to fly.

*Now let's talk about the, er, "comet".

NASA issues each student a little white bag, and we hear it is for
good reason, because many become ill on the world's highest . Caleb 31.jpg
(by far!) roller coaster. We don't have specific names to match the symptoms, but one student got too sick to work. Another was miserable but pulled himself together and managed to work the equipment. Tough work, indeed.

We mentioned other schools on the flight. The walls of the jetliner are not only padded for when gravity suddenly returns, but are usually festooned with each university's school banners. In this photo you might note the KU Jayhawks' banner farther back in the plane.

We want to dispel, once and for all, any assumption that the Jayhawks were simply the stewardesses...............

IGVC Robotics Results Are In!

Officials from the Intelligent Ground Vehicle Competition have finally released the scoring results, and S&T has something to brag about! The IDE rookie robot builders' "triMAXion", riding high on their 6th-place Design Award, landed a very respectable 14th place out of 26 qualifying teams, many of which have been in this event for some time.
"Aluminator" suffered badly when a system that recorded its location failed. The machine could see its surroundings and proceed cautiously, but couldn't "remember" where it had been. The best analogy we can think of is the wacky "Dora" from "Saving Nemo". Plenty of enthusiasm and good intentions, but lacking the synapses to bring it all together. Suffered from a robotic lobotomy, one could say.

Anyway, look for Stereo Optikon to make a strong showing next year.

Solar Car Team Ramping Up For Big Race!

Consider this a teaser, but the renowned S&T Solar Car Team is scrambling to get Solar Miner VI on the road for some much-needed shakedown cruises. The big race starts in Plano, TX on July 13th, and the top teams hope to make it all the way to Crowder College in Neosho, Missouri the first night, the initial stage stop on the northbound trek. At Crowder all the cars will be on display as they roll in throughout the 14th for the overnight stop, and blaze out again early on July 15th.

We understand the chassis is in sound running condition and the battery protection systems are working well. The massive solar cell encapsulation process is well underway, as visitors to the SDELC can attest. Rack upon rack of $35 (each) wafer cells cover every flat office surface thanks to some solar car alums who rode to the rescue last weekend. In another week or two Solar MIner VI's muted kevlar skin will be transformed into a thing of technological art, so stay tuned.

Miners Celebrate Summer and Route 66!

This weekend was Rolla’s annual two-day Summerfest party featuring kids’ games, soapbox derby races, beach volleyball, classic car shows, a beauty pageant, a fabulous Elvis show, and much more!
The ’08 event had a new and up-to-date element in contrast to the traditional attractions. Several Miner design teams took time out from their work to join folks from the St Louis Science Center and St Louis Community College to celebrate technology and the programs that S&T and other technology-based institutions have to offer.

Formula SAE crew members showed off the #92 race car and talked about their great season and the team’s hopes for the California race in two weeks. A few visitors got rocked about in the Baja team’s off-road racer, and the even luckier kids rode the HPVC team‘s utility trike around the festival grounds.

To quote HPVC aerodynamics master Andrew Sourk, “We made a lot of kids happy today!” Not to mention getting some of those lucky kids excited about the engineering behind these amazing machines and the importance of a technological education.

While We Wait For Competition Results...............


We understand that the official competition results may take several more days, so we thought we'd take a serious moment to tell you more about this event. In our view IGVC is focused on sending machines where we don't want to send people, for reasons of economy or safety. To that end there were many industry and government representatives in attendance at the event, including one especially heavy hitter,

Senator Carl Levin, Chairman of the Senate Armed Services Committee. Senator Levin toured the event and described to the students how unmanned systems have saved American lives in the wars in Iraq and Afghanistan. There was even one example on hand of a battle-damaged robot, so that students could get an up-close idea of the threats faced in that part of the world.

Senator Levin commented on how important the students' work is, because these girls and guys, from schools big and small, will be directly involved in building the next generations of autonomous vehicles that will serve our nation, and society in general.

While the Miners didn't field their long-term robot "Stereo Optikon" in the event, they did display its sophisticated their speedy all-wheel-steering machine to other teams, It even attracted significant interest from defense contractor Raytheon. This IS serious business.

Anthropomorphism and AI; Have We Built The Robots Too Much Like Us?

When we talk about AI, we think a purely rational and reasoned approach to a problem (think Spock) but some machines seem to exhibit distinct personalities. More than one ‘bot has blithely navigated the lined travel avenue only to panic at the first obstruction, turn tail, and run back from whence it came. The leading team’s unit swept past barrel after barrel with aplomb only to loose its composure on a bridge as if it were afraid of heights. And some entries look at the barrels as a chance to go bowling and charge through with reckless and fun-filled abandon. S&T’s youthful “triMAXion” is no exception as it rocked a barrel with a good (?) solid hit.

When clouds block the sun, the quick changes in ground contrast seem to confuse some machines. And somewhat lower on the food chain are the machines that think it is Groundhog Day; they see their own shadow and run back into their burrows.

Miner Baja Team Rallies, Completes Race.

Chief Engineer Wes Thomas reports that Baja’s second event in an ambitious racing season was successful. After early breakdowns in the season’s first SAE event, the mudders finished ALL events at the Caterpillar-hosted mud-slog. They finished on 65th place out of 94 teams that showed up, and had a strong finish (27th) in their first-ever rock crawl, which is very good considering they didn’t have their rock specialty vehicle ready and raced their general purpose quad instead.

Wes reports “this was a learning year. We fixed the stuff that broke in Tennessee, but found new weak points. Our car was also heavier than last year (and at ~500 pounds a good 150 more than the fast teams). I am still waiting to hopefully get some judges’ feedback as to why we didn’t fare well in design, sales, and cost, so there should be a significant improvement next year. It's most likely because we report our numbers accurately”.

He continues that “maneuverability would have been better, but two bad thunderstorms turned the course into sticky clay that wouldn't come off tires. It was like driving on ice, spinning the tires at 5 mph on flat terrain. You couldn't even see the tires after just a short run”.

“We're also hoping that having two running cars and a design ready to go by next semester should help with member retention. If finances and team member ability allow, we should have a complete, competition-ready car by December. The chief engineers will spend time trying to teach the new kids how to actually build stuff so the designers can do their job, and reduce the risk of burn-out by year’s end". On students, not clutches, we think he means.

They've also come to the realization that it takes a lot more money and outsourcing then initially thought to field a competitive car these days. They’re already working on designs for next year to simplify the car, cut costs, shed weight, and improve reliability, and already have a lighter, more efficient transmission picked out.

Wes lastly comments that “we tried to do too much with too little and the team suffered. Lesson learned".

We can’t think of better way of summing up experiential learning, because this is all about learning. Thanks for a truly brilliant summation, Wes.

What Did We Do On Our Summer Vacation? If We Told You We’d Have To Kill You!


Two S&T grad students working Boeing's Phantom Works this summer have flown in to help Aluminator figure out its coding issues. Ryan Meuth and Paul Robinette, 'bot team veterans both, took the overnight flight from Seattle to help work out some stubborn electronic issues. Both are working on a program that will allow perhaps hundreds of robots to “swarm” an objective without the help of an on-the-ground operator used on the Predator-style drones. It is kinda hush-hush, but we can let on that it involves programming toy helicopters to do things the manufacturer never intended.

There's just no telling where a S&T education will take you.

S&T's Rookie Robot Team Makes The Design Finals!

Day three near Detroit sees only about one third of the teams have qualified for tomorrow’s race, and one of those teams is from S&T (of course)! Out of about 40 teams the upstart IDE team's triMAXion joined Princeton U as one of only six teams in the design finals, and will get a chance to move even higher in the rankings when they repeat their presentation to a tougher set of judges.

They spent all their efforts (and miniscule budget) on using an existing commercial mobility platform (electric wheelchair) to which they mounted a high performance (Mac) processor, devised a simple but elegant (Mac) modular control system, and mounted a single stylish (Mac) iSight camera that costs about 1/10th the price of most other visual systems in use at the event. They clearly designed to the objective with a simple, effective and reliable machine, and to save cost they even made the upper section out of scrap lumber, but it looks pretty sharp anyway. Smart, too (Mac). **No disclaimer needed to figure out what platform THIS is written on.**

"Aluminator" has run into a few problems, most of which seem to be caused by bad cables.
The Miners have repaired the short circuits but are now worried that the cables may have damaged the motor controllers. They are reprogramming the path planning to run without wheel sensor feedback, which should make the craft a bit clumsy, and they'll have just two time windows in which to qualify or else just become observers.

We Interrupt This 'Bot Fest……….

S&T’s Baja team is back on campus after their ambitious second ’08 design competition, and they report a significant improvement over the race in Tennessee. You might remember that they withdrew from the last month’s grueling endurance race with a shattered CV joint, but we hear that they finished ALL the events at Caterpillar’s sprawling test facility near Peoria. We’ll have more info as we get it, but in the meantime here are a couple of shots from the earlier event.


The team had probably jettisoned the floatation chambers because the Peoria event substituted a rock crawl for the amphibious challenge.

Did we mention that Caterpillar is a top supporter of the Miners’ design teams? They LOVE to hire our competition team veterans because they know our grads can contribute to their goals as soon as they walk in the door, and CAT shows their gratitude by providing some pretty heavy cash support to the SDELC and all its teams.

Artificial Intelligence And The OS Struggle

The core concept of the IGVC event is to wed mechanical systems that DO the work, with the Artificial Intelligence (AI) programs that CONTROL the process, just as our brains control our muscles. A stroll through the "pit" area this weekend reveals a dazzling array of machines, programs, and design approaches that serve as the cerebral part of the process. Advances in AI (with an emphasis on INTELLIGENCE) seem to parallel the growing number of Mac laptops in heavy use on many teams; a quantum leap in the "I" part of AI in the view of many. We counted at least two dozen Macs up and down pit row, where virtually none existed last year.
In discussing this phenomenon, someone asked if anyone at the event was using Vista, so we searched high and low, and did, in fact find three Vista users, whose images follow:
