Central Maryland District Event 2017

After 14 years, team 1389 has finally won an event!!!

The team was prepared for this event. The robot was tweaked. The awards team was on top of their game and the drivers had tasted the finals and were ready to try and get that blue banner.  But, the weekend started off a bit rocky.  The robot was not performing up to snuff for the first 3 matches.  But, the team rebounded and started to get the some wins.  And these wins were sweeter than those two weeks earlier because we were doing the caring.  The team went from 3 gears per match to 5 gears per match.  But then we started to trip on Sunday morning. What should have been 3 big wins turned out to be 2 wins and a loss, putting us in 13th place at the end of qualifications.

We knew we were going to be in eliminations since we were the only robot with a consistent gear pickup at the event.  And sure enough, we were picked up by the 5th seed alliance as their 1st pick.  First we knocked out the 4th seed, then the 8th seed and wow….we were in the finals again before we knew it.  On top of that, we had figured out how to score fuel for the first time, so now we were doing 4 gears, 1 KPA and a climb.  And that is exactly what we did for two big wins in the finals.  The team had finally won an event for the first time in its history.

Thanks to 1111 and all of the volunteers for making this weekend happen.  And congrats to all of the award winners;

Here are some match videos from the weekend

Build Week 4 2017 is in the History Books

What a week. awards, robots, planning for districts, designing t-shirts, testing final designs, finishing cad, assembling the drive train and more all happened this week.  On top of that we picked up nearly 8 new team members which brings us up to 54 students, making this the largest team we have ever had.

Let go by sub team

Awards – the awards team is putting the finishing touches on all of our awards.  we have awards due on Feb 9th and Feb 16th.  We also have a chairman’s video and a tech journal du by our first competition.

Planning for districts – we have a the pit map nearly worked out and are almost finished planning food. we are going to need a lot of help at our event being held at Walt Whitman High School on March 10-12.

Designing t-shirts – we are nearly done with our t-shirt design for the year.  Last chance for sponsors to get on the t-shirt is Feb 12.

Testing final designs – the team spent the first part of the week nailing down the geometry for the major robot components.  We are going into his season with a much better understanding of how different designs interact with the game pieces.

Finished CAD – now that our final testing is done we were able to complete our CAD. We should have something to release in the next few days.

Driver practice – drive practice continues for the 3rd strait week.  But tis was by far the coldest driver practice yet.  Since we set up outside things can get a little chillie.  Driver practice this week could have gone better though, we were plagues by breakages of all 3 working drive trains.

Drive train – the drive train is fully assembled and functioning.  We even used it for driver practice this week.  We were able to identify a few problems with the design and spent some time on Saturday getting the issues fixed.

Pneumatics – As part of this year’s drive train we have had to re learn pneumatic since we have not used them in the last few years.  We found a few leaks and learned how the pneumatics system as a whole worked.  Our system is now leak free and functioning correctly with 4 actuators.  This week we add 4 more.

Electrical – we now have our electrical board designed and mocked up.  We are putting the finishing touches on the CAD and will be getting that cut this week.  This will be the first time we have had a CNC electrical board and accounted for all of the wire runs and tubing runs.

Fabrication – We are up an running on one CNC machine this week and will soon have a second CNC running to do larger pieces. By this time next year the team will be able to make nearly all of our own parts as custom as we can design them.  This is a big step forward for us and should result in lighter more efficient robots going forward.  Also, our bumpers are nearly done.

The Robot – We are only a few days behind our schedule, but tis year’s schedule is aggressive.  We want to be completely done with the primary and secondary goals by the end of week 5 so we can work on our tertiary goals during week 6 while the code and drive team work out all of the kinks.

Scouting – our lead scout has joined the drive team this year, but that has not stopped him from putting together the stats on who we will be seeing at our week 2 event.

Coding – the team has been working on the driver station UI, octocanum code, manipulator code, vision code and Ohm (our initial build).  We have instituted code reviews and organized code merges.  This is has been helping ensure our code team that is 8 members strong aren’t wasting each others time.

Safety – we had some serious safety issue this week so we had a complete stand down and made everyone go back through tool safety training.  This was the closest we have ever been to a serious injury and definitely help put safety into perspective.  We may have lost a few hours of build season, but the time spent making sure we have a safety culture is worth it.

 

 

We Now Have A Booster Club

Some of our current and past parents have gotten together with Walt Whitman High School and started a Booster Club. Team 1389 Whitman Robotics Boosters, Inc. will be a non-profit entity that will help the team with fundraising, organizing and long term planning.  This is great news for the team on the fundraising front as this will open doors to the team to be able to apply for grants that it has historically not been able to apply for and target businesses that support non-profits.

As we have, the team will remain as a club at Whitman, this will not have any impact on our status as a club at the school.  The team will continue to act as it always has, this is only a change in the business operation to maximize our fundraising potential.

We will be submitting our 501C3 paperwork in the coming weeks and will work hard over the next 5 years to earn our accreditation from the IRS.  In that time we will be able to everything a 501C3 does.

 

The board consists of

Farish Perlman, team coordinator – Board President

JJ Biel -Goebel , lead mentor – Board Vice President

William Prinz, parent of Team 1389 alum – Treasurer

Elizabeth Williams, parent of current Team 1389 student – Secretary

Dan Chen, Walt Whitman teacher – member

Alan Goodwin, Walt Whitman principal – Ex-offico

Elizabeth Hillard, Walt Whitman Business Administrator – Ex-offico

 

Team 1389 and the new Board look forward to continued growth of the team.

If you have some time and want to help out we would love to hear from you.

Lots to Review From Week 3

We started off last weekend making some parts on the CNC machine for our drive train. We learned a lot more abut zeroing than we bargained for as we found out the CNC machine was not fully calibrated in the Y. we will have that fixed on future parts.

Next up, we did some high speed driver testing to start to get our drivers used to 16-18 FPS.  Wow is that fast.  We have been getting our cycles down and have started looking at sight lines.

Our vision team was also hard at work.  We were able to get our hands on some reto reflective rope and found out we could create an auto centering teleop assist command to help us hit the rope with more accuracy.  But, we also learned that retro reflectve ropes are illegal so that is out.

Our chief strategists has been running field simulations to better understand how many balls we will be able to pick up and how quickly we can load up after all o the hoppers are empty.  It looks like the corners are the place to be fore picking up balls in a hurry.

And of course we have been building and prototyping.  We should have our drive train driving around today because of all of the great effort that has been put in this week.  On top of that we have a much better idea of how our gear intake and ball intakes will work.  As an added bonus. if we get the main robot fully functional by next Saturday, the tea already has plans for adding a high goal shooter.  If that is the case, shooter prototyping would be on the schedule in two weeks.  much earlier than we planned.

More videos can be found on our 2017 build season play list

 

Still Working on the Details

Last night the team was hard at work on some of the details of the final robot.  Roller intake for gear, roller intake for balls, octocannum sensor and software testing and climbing refinement.  We also did a quick review of the CAD that needs to be finished today so that we can order the remaining parts today.  Tomorrow the team will do a final design review and then start assembling the drive train. So that next week we can start driver practice and mechanical assembly.

It also looks like we picked our human players, now they can start practicing next week as well.

Have you called your sate officials about robotics yet?

 

Please Pick up the Phone and Help Robotics in Maryland

FIRST in Maryland Friends we need your help! See Delegate Kirill Reznik‘s message below. Call your Senators, Delegates, and the Governor to let them know how important state funding for robotics programs is in helping our children prepare for high skill and high paying jobs in Maryland! lease call his office at 410-974-3901.

From Reznik’s office on the Maryland Robotics Education bill that passed with overwhelming bipartisan support
Dear Friends,

As you may have heard, yesterday Governor Hogan announced that this year’s proposed state budget will fully fund all mandated programs, cut virtually nothing, raise no taxes, and come in under last year’s budget in real dollars.
Unfortunately, this miracle budget uses a number of budgetary gimmicks to reach that goal and uses a separate piece of legislation to eliminate a number of funding mandates. Though I have not seen the full budget yet, I have been told that the bill we fought so hard to get last year to provide for a grants program to the robotics programs throughout the State was included as part of his cuts.
Given the enormous power that the Maryland Governor has over the State budget by Constitutional authority I don’t know if we will be able to restore it. I will try my best, but I need your help. Please call your Senators and Delegates, and also please call the Governor’s office (governor.maryland.gov) and tell them how important this funding is to our children and their future. Let them know that in order to create high skill, high paying jobs in the State, we need to invest in STEM education, and not cut those crucial programs.
I hope that by the time this session is over I will be able to report to you that we have restored this program.

Sincerely,

Delegate Kirill Reznik

Lots of Big Learning Today

The team came back from its three day weekend with a vengeance by making 3 gear picker uppers, a revised climber and got pneumatics working.  As a bonus, the team has found ourselves a new programming mentor and he has jumped right in by helping the kids organize their code.  Things are looking up.

As an added bonus, we have a finished airship to practice on and updated liftzilla drive train to start high speed driving with.

We have also starting trying to figure out the robot’s name for this season.

Additionally, the awards team is in full swing and we are working hard to get our awards videos done.

As if all that weren’t enough, the team is starting to plan our district event that we are hosting in march.

We Have Our Design Requirements Defined

We met yesterday to go through everything we learned this week and to come to a consensus around our design requirements.  It took a while, but we think we have settled upon a design and are readt to start detailed CAD. On top of that we started to prototype a new feature that was added today.  The ability to pick gears up off the ground.

Here is where we ended up.

  • Primary – Climb rope to the top in 10 seconds from touching the rope and stay at top past buzzer
    • Capture – Drum based
    • Capture – Use fingers
    • Capture – Use rotation
    • Capture – Catch fast 1-2 seconds)
    • Capture – Need driver camera for davits 1 and 3 to work with driver station 1 an 3
    • Climb – 5-8 seconds to top
    • Lock – Use ratchet wrench
    • Rope – Narrow rope
    • Rope – Big knot on end (monkeys fist)
    • Rope – Retro-reflective for auto assist
    • Rope – Be stiff and heavy
  • Primary – Pick up gears from the ground and drop them off at the peg with a max of 20 seconds per cycle
    • Intake – Drive by control
    • Intake – Scoop from ground while driving
    • Intake – Combine with passive design so it can pick up from feeder station as well
    • Intake – No drop design
    • Intake – will use 8″ arm to pick up gear
    • Stowage – No bump drop design
    • Deploy – Passive design
    • Deploy – Make space for peg
    • Deploy – Use drive assist camera
    • Deploy – Use auto assist code
    • Deploy – Use air ship pilot to pull gear out of robot
  • Primary – Be able to drive nearly 20ft per second and be highly maneuverable
    • Drive – 18-20 fps
    • Drive – Sideways or alignment for gears
    • Drive – Sideways for alignment with low goal
    • Drive – Octocannum
    • Drive – 4″ wheels
    • Drive – Un-actuated position is solid wheels
    • Chassis – 24″ x 24″ x 24″ or 30″ x 30″ x 24″
    • Bumpers – .5″ off ground
    • Robot – Be as light as possible
    • Root – Be as small as possible
  • Secondary – Pick up balls from the floor
    • Intake – Through bumper
    • Intake – Roller intake
    • Intake – Poly chord / belt elevator
    • Intake – Use 1 motor for intake and elevator
    • Intake – Have flap so that balls can be loaded in via the hopper or feeder station without spillage
  • Secondary – Store 20 balls or more on the robot
    • Stowage – Fixed hopper
    • Stowage – Ramp to low goal
    • Stowage – No agitator
  • Secondary – Deposit 20 balls in the low goal in less that 3 seconds
    • Deploy – Low goal
    • Deploy – Movable rake
  • Tertiary – Shoot 20 balls in the high goal in 5 seconds with 50% accuracy
    • Deploy – Use intake elevator
    • Deploy – Have two high goal positions, airship gear 1 and airship elevator gear 2
    • Deploy – Have a wheeled shooter

Over the next two days our CAD team will work on creating the robot design.  And over the next week the team will refine that design with detail prototypes. So that buy the time the parts arrive in week 3 we have the final dimensions figured out.

A big decision we made today was to use Octocannum.  This is going to be a big challenge for our team since we have not used this drive before.  We know it adds a lot of risk, but we feel the possible advantages combined with the learning we will do make it worth it.

Robot systems we need to build will have 9 motors and 8 cylinders / solenoids.

  • The Octocannum drive will require 4 cims, 4 encoders, pressure switches, 4 pneumatic cylinders, 4 solenoids.
  • The ball intake and elevator will require 1 motor for ground, 2 pneumatic cylinder and 2 solenoid for the hopper
  • The low goal scorer will require 1 motor with an encoder
  • The gear intake will require 2 pneumatic cylinders and 2 solenoids for moving the arm with 1 or 2 motors with encoders and IR range finders on the arm.
  • The climber will require 1 motor and 2 IR range finders

 

Here are some images from today.

Design Review Day is Here

Today we are going to review everything we learned this past week and make some big decisions.  Today is critical because it will lock in the robot design requirements and give our cad teams the green light to start detail design.  This is also the last time that all of the students will have the ability to impact the robot over all.  Next week, each student will be assigned to a detailed prototyping team whose goals are validate CAD.   Last yea we were snowed out of week 2 and part of week 3 and did not have a chance to do these detailed prototypes.  The lack of validation data definitely hurt us, as out first robot design had some major issues that were only discovered on the final robot.  These week 2 detailed prototypes will be key, if we want to be successful this season.

Some of the questions we have to answer,

  • Do we have any priority changes, will we add, remove or shift any of the below items
    • Primary – Climb rope to the top in 10 seconds from touching the rope and stay at top past buzzer
    • Primary – Pick up gears from feeder station and drop them off at the peg with a max of 20 seconds per cycle
    • Primary – Be able to drive nearly 20ft per second and highly maneuverable
    • Secondary – Pick up balls from the floor
    • Secondary – Store 20 balls or more on the robot
    • Secondary – Deposit 20 balls in the low goal in less that 3 seconds
    • Tertiary – Pick up gears from the ground
    • Tertiary – Shoot 20 balls in the high goal in 5 seconds with 50% accuracy
  • How will we climb
  • How will we receive gears from driver station
  • How will we store gears
  • How will we deploy gears
  • What drive train will we use
  • What configuration will we use A or B
    • A. 36 in. by 40 in. by 24 in. tall (~91 cm by 101 cm by 60 cm tall).
    • B. 30 in. by 32 in. by 36 in. tall (~76 cm by 81 cm by 91 cm tall).
  • How will we pick up balls
  • How will we move balls
  • How will we store balls
  • How will we deploy balls

Once all of questions are answers its on to the decisions.

The great drive train debate continues

After reading the rules and breaking down the game last weekend the team determined we both extreme speed and high maneuverability.  We looked at what the FRC 836 th robobees in 2016 were able to accomplish with a simple bot and tons of both. With that we have identified a few options for this year;

Over the last few days the team has been researching and testing to gain enough information to fill in a trade study and we are getting close to picking a winner.  Check out our current thoughts here.  We still have a few more days to gather as much knowledge as we can, making this one of the most talked about thinks on the team this week.

Here are some of our prototypes
