Today I saw a very cool video that makes me envious that I don’t have the skills to build something like this, yet I am in awe of the people who did this. Quadcopter formation flying FTW.

A few of years ago before I was at IFI, this video was made to show how parts are made for our robots. We are fortunate to have such a resource and have adapted many different processes for robot design specifically around these abilities (such as stacked plate aluminum gears)
If you haven’t seen it enjoy, if you have seen it….well it is always a good show.

Hey check out this part from team 148′s 2012 robot. Isn’t it pretty! I wonder what is does? Does it reveal that super secret feature which will give us an advantage?
In actuality this tells you nothing about our robot, except that it will be black and made from sheet metal.
Just like most teasers that make their way to the web during this time of the year, for the most part they are a waste of time. If you are urgently trying to show off your thinking then you should post your whole robot design. Or at a minimum the complete mechanism. Posting a close up picture of a sprocket or gearbox (especially one purchased from andymark) is not really a good representation of your robot or your team. In retrospect I might consider a team who is extremely proud of something like this, to have questionable design abilities.
I understand the desire for teams to gain recognition, but this is the wrong way to draw attention to yourself. Post videos to youtube, full photos of mechanisms, or your whole robot. All of these things are great ways to showcase your work! Even I have fallen into this trap years ago, but I have since learned better, so consider this a lesson to you “youngsters.”
On a side note, as much as I tried, Jeff removed those words from the bottom of the sheet metal.

I had the opportunity a few days ago to spend some time with some long time friends team 340 in Rochester NY. We got into a conversation about building to your team’s resources and how that can effect how you interpret what is important about the game. I have been fortunate in my 11 years with FIRST to be on many teams and see things from many different perspectives. I have been on teams that had everything you could ask for (money, machining, space, supportive parents and teachers) and I have also been on teams with no more than $500 in their account where we built the robot in a garage with parts from dumpsters (yes, literally I have been dumpster diving for robot parts) . What all these different situations has taught me is a very important lesson, not only for FIRST robots but for life.
BUILD WITHIN YOUR MEANS!
This concept can be difficult because I believe it is everyone’s deep desire to be the best at very scenario, and sometimes building within your resources means making choices which can limit your potential. Yet even limited your robot actions can actually make you a better competitor since you will be more optimized.
I had a conversation with another 10+ year mentor a few days ago about drives, and how difficult it was going to be without 2 speeds this year. He was struggling with the fact that on his new young team they really can’t afford the ~$640 for a set of shifters but without them the team would be at a huge disadvantage at the competition. While I agree that having 2 speeds would be a benefit this year I can condone spending almost half his robot budget just on transmissions.
This is exactly the type of thing I wish teams would realize that if you don’t have the money for fancy robot parts, or you don’t have access to heavy fabrication equipment, you should approach the game in a different manor. For example I know that many teams think it would be totally awesome to build a turreted top basket shooter, with camera tracking that can shoot from anywhere on the field and have a mystery device that can guarantee a 3 balance every time, and a drivetrain that can drive through defense while having excellent acceleration and top speed. While this robot is possible for all teams is it feasible for most teams? I am not trying to discourage teams from pushing themselves, yet I am encouraging teams to take a hard look at their resources to they can make the best decisions. Is it worth spending all of your time and money on a single portion of the robot while hurting the other subsystems.
At this point in the season, I am sure many of you are far along the path for whatever you decide, but when you run into issues or feel overwhelmed, take a step back and see if what you want to build is what you are actually capable of or if you are over reaching.
And now for your moment of zen.

Every year since 2006 I have been categorizing robots into groups based on what I expect to see each year. Many of them are not politically correct, but regardless they are true. In most years this info is normally kept between myself and friends but this year while I am blogging away, I thought it would be fun to share.
Jack Bot – Normally the most common robot out there this is a robot that is a jack of all trades, but master of none. In 2012 The jack bot will be ones that have the ability to climb the barrier (if they are lined up perfect), Shoot a basketball (from a few specific spots on the field), and balance the bridge when the circumstances are right. Not a bad robot to have at many regionals, but I still believe in focusing on 1 or 2 things and being the best at them instead of spreading the skill around.
Flying Pig – This is the robot that is designed to pull off an impossible strategy, and since it is an impossible strategy the robot fails. This year the flying pig will be a robot who can score a basket from the other side of the field (like right infront of your human player) with good accuracy. (prove me wrong if you will)
Brick – Bricks don’t move, neither does this robot.
The man – The ultimate robot for any game, The one who diecets the game correctly and is the best robot on the field. When you hear teams reading the schedule in the pits and groaning when they see your team number, you know you have built “the man.” There are a few teams that are capable of this every year, but on any given year you can build that robot. This year the man will be…..ha ha, nobody knows until the game plays out.
The bucket – “there is a hole in your bucket dear Liza, dear Liza” A robot filled with good intentions but unfortunately those good intentions are leaking all over the floor. Alot of times this is a team with a really good idea, but without the resources to pull it off, so they use strange things to make it happen, such as the tote the KOP came in.
LineRobot – Being a lineman, means you like to hit people. Being the LineRobot Means you like to hit robots. All Defense, nothing else. The drivers on these teams are typically the most relaxed at the regional because they get to take out their aggression every match.
Alley-Oop - A robot that is designed for a co-op strategy, and needs a good partner to pull it off. Many times teams will try something so outside the box that they can’t do it themselves, but when they are successful, the world takes notices. In recent memory 469 in 2010 was both the “alley oop”and “the man” all wrapped in one.
Hungry Hippo - Also Known As a horder, this robot’s job is to collect as many game pieces as is legally (or illegally) possible and drive around with them hoping to make the game changing move. In some games it is great to hord game objects, and I believe this is one of them. With 18 balls on the field and the ability for the human players to hold 12 (6 on each side) if you can defensively hold 3 of them, you leave the 3 extras for all other teams to fight over. How many matches will reach a “ball-less state” by about 1 min in?
