Sample Schedule for FIRST 3 weeks

Hey every one, due to work, I’ve been out of pocket for a while…But it’s Robot Season and time to really get down to the most fun work you’ll ever have.

Scroll to the bottom for Woodie Flowers presentatono from the kickoff.

To all the Rookie teams: One problem I’ve seen in the past is, teams that have never been through this get over whelmed easily. Between the robot build, reading the manual, and organizing the team with kids who have never been through this before either, time gets away from people. Teams will put off building the robot until the last minute. This is a huge problem because a robot is not built in a week. Here is a sample schedule for when things need to get done.

Please try not to stress out too much and remember there are people out there who can help. Look at FIRST event at the teams that will be at the event you will be attending and contact one of the veteran teams. They’ll usually help. Or contact your regional director, or contact me and I’ll see what I can do to help. I’m Joe Varnell, Engineer at Lockheed Martin, Technical mentor for Team 704, and my e-mail is frc704mentor@qweztech.com. I don’t want the rookie teams to get stuck. Also, don’t wait until the last week of the build to get help. Ask as early as you can.

Organize your team. There needs to be programmers, electrical people, frame/gear/build people (i.e. gear heads). Unless you have a large team, everyone will probably be doing a little of each. Plus, some kids may want to try it all so they can see what they are most interested in. There should also be a student team leader who knows what’s going on in the various parts. FIRST has information on organizing teams at this link (http://www.usfirst.org/roboticsprograms/frc/mentor-resources-library).

Week 1 – Figure out “What” needs to be done (Requirements) and “How” your robot will drive

Read the manual!!! This is probably the hardest part because there is a lot of other stuff to do and people, especially kids, want to get on with the robot building.

Analyze the game and the rules for the Robot. Figure out your drive train.

Brainstorm on what how you’re going to do things. Remember when brainstorming, no idea is a bad idea. Some ideas that seem to be “out there” may start other people thinking about different ways of doing things. Once you have a bunch of ideas, start narrowing them down to idea’s that can be implemented by you. You can also refine some of the ideas that have already been brought up.

Have the programmers start testing the sensor’s, learning the language, and running the example programs.

Find someone who can help with building using whatever materials are going to be used on the robot. Some teams will use aluminum, some use carbon fiber, possibly fiber glass, and many people used wood (Last year many teams used wood). A mediocre to good machinist can really help a team.

Week 2 – Continue design and prototype

Figure out what type of appendages and apparatuses you need to do the job you want and try some stuff. Issues that should be though about are things such as, this year is a shooting game, do you just want to dump balls in the lower basket? Do you catapult like arm to throw balls? Do you want something like a baseball pitching machine?

Build prototypes to test the designs. Prototyping is just rigging up something that is similar to what you want and seeing if it will work. You might use wood or PVC. Be safe while your prototyping, sometimes the apparatus need to be held together by hand while testing.

Begin building the chassis frame, put on the transmission, and figuring out where everything will go.

Week 3 – Build the drive train and continue to prototype.

Continue on with building the Chassis, putting on the motor’s, wheels and chains.

Finish up prototyping the appendages and apparatus. Once you get something decided for the apparatuses and start building it.

Good luck

FIRST Competition Season

FIRST Robot build season for 2011 is complete and now it’s on to the FIRST Competition season. Starting March 3rd the FRC events begin, time for your robots to pucker up…assuming you put that feature on your robot.

I’m going to be a volunteer at the San Antonio FIRST Regional event. I’m going to be working Field Technical stuff. I would appreciate it if anyone is there would drop by and say hi. Since you don’t know my face, ask where Joe Varnell is; that’s me.

I’ve had several rookie teams ask “What should I expect at the competition?” Here are a few things to think about beforehand:

  1. Make sure you bring safety glasses and gloves. All the competitions are fairly strict on wearing safety glasses in the pits.
  2. Be prepared to work on or fix your robot! Bring tools, tie wraps, extra parts in case your robot breaks, duct tape (which is good for everything)
  3. One good idea is to bring ice chests with food for lunch. A lot of teams will be outside having lunch and relaxing during lunch. It’s also cheaper that way.
  4. Read the rules on what to bring. You’ll need a bill of goods, a list of items on your robot that didn’t come out of that years kit.
  5. Bring a long Ethernet cord. They don’t allow wireless communication in the pits so you need to tether your robot in the pits.
  6. Be prepared to keep your batteries that you are not using on the charger. This is so you can have a fresh battery for every match.
  7. Have a banner to display your team number, team mascot, and your sponsors. You should always support your sponsors.

At the competition, on Thursday, be prepared for:

  1. Robot weight in. After you get your robot unpacked and put together you’ll need to get it weighed in and sized. The weight is without the battery or bumpers.
  2. Access point setup. You’ll have to take you white access point off your robot to be setup with the WPA for the competition. This is so it will communicate properly with the Field Control System (FCS)
  3. Robot inspection. Robot inspectors will come around to your pit and verify your robot meets the spec’s from the robot manual. Some of the top things they check are bumper height and that they meet bumper specifications. Also, the pneumatic pressure is 120 psi max on the storage tank side and 60 psi on the solenoid side (make sure you read the pneumatics manual). The electronics power will be checked and probably that the driver station shows the battery voltage. (this is done by powering the analog bumper and putting a jumper on it)
  4. Try to get out on the field for a practice match. This will let you see how matches are run and what to expect.
  5. Don’t be afraid to ask for help. This is important. If you’re having problems, don’t struggle to long. Ask a more experienced team, mainly those with numbers under about 3000 or teams with robots that look really well put together. Also, there will probably be some experts there who can help the teams.
  6. There will also be a practice field somewhere to test your robots operation.
  7. There will also be a machine shop in case you need parts worked on.

On Friday and on Saturday morning are the qualifying rounds.

  1. Be prepared to answer the judge’s questions. There will be judges in blue shirts walking around asking questions. They are judging various categories and there should be students around (except during matches) to answer questions.
  2. Get your robot to the robot queue when it’s called. Look at the match schedule and see about when your matches are. Also, listen for your team number to be announced and get to the field quickly.
  3. Make sure you have time to look around and to watch other teams. This will give you ideas for next year.
  4. Talk to the veteran teams and make friends with them. The next year you can probably go out to other teams and see how they operate.
  5. Before your matches, talk with the other teams you have alliances with. Be a team player and plan your strategy. Learn each of the alliances robots strengths and weaknesses and plan what each team should be doing.
  6. Because of the random alliance parings, even rookie teams have a chance to be in the finals.

Saturday afternoon are the finals.

  1. The top 8 teams will be picking alliance partners, be prepared to pick just in case you make it to the finals. If you are choosing alliance partners and don’t know who to choose, the team rankings will be on the screen (probably behind you). Look at that and pick the top numbered team on the list.
  2. The rules of how to alliance pick will be explained. However, if you don’t understand then ask someone.
  3. If you are in the finals, have fresh batteries ready to go. Make sure your batteries are charged. The finials are fast paced.

I’ve probably left out some things and I apologize for that. There will be a lot going on, don’t let it overwhelm you.

In a nutshell, this is what will go on. My closing advice is to get plenty of sleep, be friendly, eat breakfast, talk to other teams, and, above all, HAVE FUN! It will be hardest fun you’ve ever had.
