Final Fixes

While reading this, open up our YouTube page in a new window and let some of the videos load. TONS OF UPDATES!
Today was mostly spent doing some last minute fixes on the robot before we box it up tomorrow. It's incredible to think of where the team was last year (working crazy hard, stressing, sweating, barely making it) and where we are this year (refining, finishing, working on nice but not necessary additions). Our main accomplishments today were autonomous, the new horn, chains, and movies.

Stumbling Blocks

After so much success with prototypes and so many things working out with the team, it was inevitable some challenges would happen for the team soon. Unfortunately on Saturday, we ran into (literally) a big challenge: the bump in the middle of the field. We spent the past two days working on a wheel system that would get us over the bump and it didn't work. We also started working on vision processing (for finding the hoops) and an arm to push the bridge down so we can drive over it. Luckily, those went a little bit better.

First off, there are a couple visual changes to the blog. You probably noticed the new header visual (thanks Jenna). We will also be adding the Team Members page and a page describing our team and the mission of FIRST in the coming week or so. So look out for those.

In case you didn't know, the field for our competition is divided into two halves. Dividing these halves is a 4" tall by 6" wide bump and 3 bridges. Traversing these obstacles is essential to playing the game. Brandon, Ryan, and Tyler worked their butts off making a system to lower the bridge the past two days. It is really sweet! It's an arm with an angle piece coming down. It will rest on a platform with an L shaped plastic piece that is connected to a spring. At the beginning of the match, we will drop the arm and the spring loaded L shaped piece will keep the arm down during the match. I will upload some pictures on Monday which will make it easier to see. We haven't tested it yet (gulp) but we will do that on Monday. It looks awesome and it follows the big rule of KISS (keep it simple stupid).

The major project we worked on though was the wheel system. On Friday, we took the whole bot apart and started changing the wheels. We had to drop our wheels down so that the frame could fit over the bump. This is a much bigger task than it sounds. It requires cutting and drilling new axle holes in 12 pieces of extrusion. Then we had to put new chains on each gearbox and make new spacers for each wheel. This is a LONG process that we spent literally 9 hours on Saturday working on. Bryce's dad came and helped get the chains and spacers ready which was really nice. So we were feeling really good after getting the entire robot back together and the wheels on and working. Until... we tested it. There is a YouTube video up of the test. We were all so tired that you can't really tell how disappointing it was. However, the team is resilient and will think of another mechanism to go over the bump. No worries.

Colin and Megan worked on getting the image processing for the camera going. The LabView programming has the power to recognize shapes and colors including the metal rectangles behind the hoops. This will allow us to program the robot to find the hoops and aim for us. 





Our energy was still really low after working for so long during the week. Plus, the team members are still students and involved in many other things (including work and church and speech and homework). They're commitment is incredible and inspiring. We are half done! That's both awesome and scary. The challenges presented to us will be overcome though.We ended the night by playing some Rock Band to relieve stress.

Blast From The Past

As usual after such an awesome and amazing couple of days where we accomplished SO MUCH, today was a little bit of a thinking and figuring out what to do next sort of day. That doesn't mean we did not accomplish anything, just means we were a little more sluggish and a little less focused. The big accomplishment for today was that we made an angle adjuster mechanism for the shooter. We also continued work on the mascot.

When playing the game at the competition, we want to be able to shoot from different places on the field. To facilitate this, we wanted to adjust the angle of the shooter so we could shoot lower or higher depending on where we are and our battery life and many other factors. This post is titled this way because we ended up using one of the big components from last year: a lead screw and window motor. Last year, two lead screws and two window motors powered our scissor lift. This year, they are powering our angle adjuster. Tyler, Brandon, Bydlon, and Bryce worked on this mechanism. It works great. Colin almost finished the programming for it but had to leave. This will be totally operational tomorrow.

The other big build project was that we wanted to have a sweeper in front of the gatherer. Ryan worked hard on getting it all together. Unfortunately, when we got it all wired up, it kept blowing out fuses and the surgical tubing kept getting stuck in the conveyer belt. So, we decided to keep the sweeper off.

The big electrical project was wiring up the LED's for the driver station. We have a toggle switch so the driver station can light up red or blue depending on which alliance we are assigned.  Bryce and Demian worked on this aspect. The driver station is now complete.

Steph, Jesse, and Gabe kept working on the mascot. They finished the head yesterday and have moved on to the body. Making the dimensions right is a hard task. There are no measurements in what we found online about the mascot so they are basically guessing and checking as they go. This makes work slow. They are plowing ahead though.

Tomorrow will be a better day for work. We will be more rested and more focused. We will have a full team meeting, finish the angle adjuster, and our big goal is to start working on our "tusk" idea for bringing the bridge down. Thanks for reading. Go team 3313!

Pictures Are Worth A Thousand Words

So much excitement to be had today! We finished the practice hoop set up. We refined the gatherer and shooter. We made a bunch of baskets. We totally finished the mascot head. We built supports for the gatherer and electrical board. We got a story posted in the Echo Press Newspaper. Todd (Alex Tech professor) stopped by.  We finished the business plan draft. We got the camera to work. So super awesome. I'm too excited to type. I'll just post pictures instead. Click on any to see them bigger. Also remember to check out YouTube for videos from today.

SO AWESOME!

MAKING BASKETS!
We have a messy robot room...

Fasten Your Safety Belts

Sorry for the late post tonight. The three big projects for today were putting the robot parts all together, building the hoop apparatus, and continuing to make the mascot head. A couple new videos on YouTube to check out as well.


Bydlon bought more belts (thus the title) for the gatherer last night so Ryan spent most of the early part of the afternoon fixing the gatherer dowels to work with the added belts. The added surface area of the additional belts really helped catch the balls and propel them up from the ground. Then Bryce, Bydlon, and Ryan worked on attaching the shooter to the top of the gatherer. The big advancement here was that we decided to switch the shooter around so it shoots over the electrical box. Kind of a big change but it makes mounting it and getting the balls to the shooter wheel much easier. HUGE MOMENT watching the balls be picked up and shot all in one motion from the driver station. Colin and Megan worked hard on fixing the programming issues with the shooter and gatherer. Now it's refining the process including (hopefully) a lazy susan (for turning the shooter), adjusting the angle (for shooting from different distances), and attaching the camera (for vision targeting). So not much to do... Not.

Another project that Damien, Spencer, and Jordan worked on was putting all of the wood together to form the base of the hoop apparatus. This will be key for refining and fixing the shooting mechanism. All that's left is buying the hoops and attaching those to the backboards. The robot room is completely full with the hoop apparatus, the bridge, the bump plus all of our other robotics pieces. It's kind of a mess right now.

Jesse and Steph continued their diligent work on the mascot helmet. They are really close to getting done with it though. They are even at the point where they tested spray paint on different test surfaces (cardboard, duct tape, and hot glue) to see how it looks. It looks fantastic.

Other small projects included:
  • More people proofreading the Business Plan by Jenna.
  • Bringing some pieces over to Alex Tech for prototyping the sweeper in front of the gatherer. (done by Brandon and Tyler)
  • Finishing up team member interviews
Another productive day with lots of rewards. Bydlon is going to a programming class in the Cities tomorrow but will be back in time to open the shop for work. Hopefully we will have a smoother transition from the gatherer to the shooter and made some progress on a lazy susan prototype. We also want to finish the helmet (other than painting) and get the camera working. Thanks for reading!

Three Exciting Moments

Another awesome day for Mechatronics. We got a lot accomplished. I realize I say that a lot but it is amazing how much the team accomplishes every day. It is a testament to their dedication and ingenuity. I am continually impressed. The biggest excitement today was that we picked a ball up off the ground, made some baskets with our shooter, started on the hoop apparatus, and made a ton of progress on the mascot head.

The frist big moment of the day was that Brandon, Bydlon, Bryce, and Tyler brought the shooter down to the gym and made 5 (!!!!) baskets in a row. It was a very exciting feeling to actually see the shooter accomplish the goal we set out for it. We tried shooting the ball with the wheel above (opposite of what we planned) and kept missing the hoop. Finally, someone suggested we switch it up and it worked! The whole idea of trying this came from a student in Bydlon's class 7th period. The fact that this never even crossed anyone's mind is slightly embarrassing.

The next super exciting moment was that we picked a ball up off the ground and got it to the top of the gatherer! Two weeks of hard work paid off in about 5 seconds. Super exciting! Damien and Molly brought some parts over to the Tech to get them cut for us. These parts were obstructing the path of the ball. We originally had some issues with the buttons on the drive station and the gatherer but Colin worked his butt off and fixed them. Our next goal is to fully refine the gatherer by having five belts. This will get finished tomorrow. After that, we need to add on the shooter.

The third super exciting moment was seeing the helmet of the mascot come together. Jenna and Jesse worked so hard on the mascot helmet today. The tedious nature of the project cannot be overstated. However, the end product will be well worth it. Great job by Jesse and Jenna on the project today.

Bydlon and Bryce bought and cut all of the wood for the Hoop Apparatus. This will come in helpful when we are testing our shooter on the real game hoop set up. The tests today in the gym were good for our confidence but as far as actually proving we can succeed... We need the real thing to work on. This should be completed tomorrow.

So many exciting things still coming up. We already checked off about 4 or 5 goals for the week which is amazing! More to come tomorrow.
