Admittedly this is completely biased as it is my old team, but I think 1058 fits this pretty well despite not being that well known. Plus I love talking about the team's history so this should be fun.
From 2003-2009, 1058 was known by others as the team who would do creative things and do well, but wasn't good enough to win events or anything. Some cool features include a giant ball catching robot in 2004, an insanely massive crane for 2005 (as well as some neat software), lots of strange uses for PVC, and for a little while a strong usage of mecanum wheels. Won a couple of awards such as rookie all star and a quality award, but never made it past the semifinals.
2010 was a breakout year for the Pirates, with a cool kicking mecanism, climber, field oriented mecanum drive, and could strafe on the bump (

The next few years however were mediocre in terms of the robot success. Once again we had some really cool designs such as mecanums with locking rollers, strange linkage arms and frisbee floor intakes that put banebots out of business, but we couldn't get back to that 2010 level.
2010-2013 was the changing point for 1058 however. The team started becoming less of a robotics club and more of a FIRST program. A student leadership system was established, funding through the town and sponsors became a priority, we started going to as many offseason events as we possibly could, and we began hosting and traveling to dozens of demos all across New England. The team won our first Chairmans Award at GSR 2012, and our lead mentor Mike Pettengill won the Woodie Flowers Finalist Award at Pine Tree 2013.
The final piece of the puzzle was to make 1058's unique robots become competitive once again. In 2014 we began a new system in how we went about design to fabrication, decided to CAD everything in detail before machining, and began making everything in house after learning how to use our DRO mills. We made our first custom frame, finished the robot earlier than we ever had, and kept to our usual unique design choices (seriously go check out our 2014 robot). This process led to an excellence in engineering award in 2014, and the same process led to more design awards in 2015 and 2016.
Present day, the team has kept to the new design method of high CAD utilization, designing from the ground up, and having students machine parts in house closer to spec than some cots parts (one of our students machined a linear bearing within 2 yen thousandths of an inch on a manual mill in 2015). The team had their best year ever in 2016, winning three district events and competing at 8 events already this season (they usually hit 7-10 a year). In the last 5 years 1058 has won 3 chairmans awards and 3 district events, as well as many different robot and non robot awards.
That was way longer than I thought it would be. I hope it doesn't look like I'm going too hard. I learned a lot after graduating from 1058 that I got really lucky with the team I was able to be on. I hear many complaints from FRC alumni about their experience as a student. I have no complaints. The student base always got along, the mentors are amazing and truly "get" what FIRST is all about. They push their students to learn incredible things and become anything they want to be. Seriously though, go check out some 1058 robots on Blue Alliance, they're all very unique machines from the normal design each year, but you can see the improvements slowly building on themselves.
Hopefully someone enjoys reading this because it took a really long time to write.
