Day 13: The Dreaded Design Review

Today our team held The Dreaded Design Review. During The Dreaded Design Review, we went over each subsystem in excruciating detail. Since we have a lot of subsystems, The Dreaded Design Review lasted for two lifetimes, four eons, and twelve eternities.

After we went over each design, the mentors and subteam leads discussed which designs to use. We decided on a high lift design and chose to keep the climber. Subteams were also reorganized due to the new changes.

While the mentors and subteam leads met, the rest of the team cleaned up the shop. A clean shop is a rare luxury that our team has not had in a very long time.

Day 12: Preparing for Design Review

Today each subteam prepared for the design review tomorrow. This included (trying to) finish prototypes, final calculations, and more. Subteams also helped teach other out to make sure that everyone's ready for tomorrow.

Some members of our team also brought our 2014 robot (CONDOR) to the Eastgate science fair. Unfortunately, many people couldn't come because they were busy with prototyping.

The programming team tested autonomous today. ("Testing" usually means "staring at a robot doing the same things over and over again"). They won't say anything about autonomous this year, except that it "works" - whatever that means.

Day 11: Iterating

Today each subteam prepared for the Dreaded Design Review on Saturday. They did so in many ways. Some subteams rebuilt their prototypes with a variety of construction materials. This included duct tape, PVC, and pool noodles.

Other subteams made many mathematical calculations to show that their design would work. They also reviewed their arguments on why their design is better.

Day 10: Gearboxes and motors

Today each prototyping team worked on figuring out the details of their design. This meant figuring out which motors and gearbox ratios to use.

We also scheduled a design review to take place on Saturday. Some teams have almost nothing to do until the design review. Other teams...don't.

Today's dinner was tacos, a delicious meal kindly brought by one of our parents. Like last year, our dinner conversations are very "weird". One thing's for sure - they make our meetings interesting.

Day 9: Working Intake (prototype)!

Today our intake team made a working intake prototype! At first, the intake only took cubes in straight on, but adding springs fixed the issue.

Climbing also decided which motors to use and worked on a third design. This innovative design is much simpler, although it does have some disadvantages.

Lift researched different mechanisms that they could use. They also worked on more calculations.

The software team programmed a robot to drive forward and then turn 90 degrees. The accuracy is decent but still has room for improvement.

Some team members also worked on making a CAD model of the drivebase.

Day 8: Wolverine Robotics Visits!

Today Wolverine Robotics (949) from Bellevue High School visited us! They brought a drivebase and ended up driving it around towards the end of the meeting.
Meanwhile, here's a breakdown of what each subteam did:

Intake continued working on their prototype today. This subteam is often understaffed, but today a fair number of people trickled in over time. (They also gained more people by stealing from other subteams).
Intake ruled out one design and began prototyping another towards the end of the meeting.

The climber subteam has two competing designs. Both of them some degree. They completed metal versions of both and began testing and refining them.

Like the climber subteam, the lift team has two different designs and worked on both today. They spent the meeting testing and rebuilding their prototypes.

Today, programming tackled two difficult tasks. One was replicating the network setup used in competition. The other was making a robot drive straight.

Day 7: More building, more decisions

Today all our subteams worked on bringing their prototypes to life! Unfortunately, not all of them were successful, but we're working on that. Each subteam has modified their design many times, to varying degrees.

Certain members of our leadership team also made the decision to use EVO Shifters. This gives us both high speed for offense and pushing power for defense.

Our software team also began creating a list of items we need to do by the end of build season, and put them online: (only accessible to team members).

Day 6: Building Prototypes

Today our team finally started building prototypes! We are using metal, wood, and (best of all) cardboard for these prototypes. While they may not look very good, they will help us check and improve our designs.

Another helpful way to work on designs was drawing them on a back of a napkin, as one subteam discovered.

We also got sweatshirts today! They are very warm and comfortable (I'm wearing mine right now) and look quite nice. The design is the same as our T-Shirts.

Today's meeting ended at 7. Our next two meetings (Saturday and Monday) will be from 9 am to 4 pm.

Day 5: Drivebase Decisions

Today our team decided which drivebase we will use. We used two robots, one with tank drive and one with mecanum, to show our newer members how they work.

We also discussed the advantages and disadvantages of each one. We finally decided to go with tank drive for the following reasons:
  • Tank Drive has more room for subsystems
  • Tank Drive has more pushing power
  • Tank Drive is more accurate in autonomous (mecanum wheels slip)
  • The switch and scale are big this year, so the ability to strafe isn’t as valuable.
Our team also had an early dinner today! Thanks to our amazing parents, the entire team had plenty of food to eat.

For the rest of the meeting, our subteams continued designing and prototyping. Some subteams will begin building prototypes tomorrow.

  • There's no school on Monday the 15th, but we will be meeting from 9 to 4.
  • Tomorrow's meeting will end at 7 instead of 6 (Please check the calendar for meeting times).
  • Thanks to all the parents who've brought food! But, we still need dinner on January 16th and January 19th. You can sign up here.

Day 4: Narrowing down designs

Today our team continued to work on our designs for our prototypes. By the end of today's meeting, each subteam was able to narrow down their list of designs. We will be prototyping these designs within the next few days.

Subteams also met with each other to make sure their subsystems work together well.
