Our Vacuum Sucks…

It’s so exciting to be in competition season now!  Good luck to all teams participating.  We’re watching webcasts and getting more and more excited for next week in Oshawa!webcastProgramming is happening so we can test our shooter tomorrow in the warehouse.programmingKnitting is happening so everyone has a team hat for competition.  We’ve got only a few more to go!knittingToday’s major project involved a lot of vacuuming!  We have spent the last few meetings working on creating a vacuum former to create our chain guards.  Today we put the finishing touches on, and gave it a try.finishingWe needed to make a mold for our chain guard, which included some creative measurements through the bag.  We’re really glad the bags are clear!  After our measuring we used styrofoam, cardboard and duct tape to create a 3-D shape that melted plastic would form to.measuringSince thin Lexan is about $80 a sheet, we had the brilliant idea of using crazy carpets instead.  They are on sale now–we’ve not had much snow this winter!  We were lucky to find some in our team colours at Canadian Tire.crazy carpetThe crazy carpet was cut out to fit on our frame.staplingWe used a staple gun to attach it.  It’s important to put the staples close together.  We used a hammer to make sure the staples were secure.vacuumNext came the vacuum contest….which vacuum sucked the most!  Our vacuum from our workroom had holes in the tube and a clogged filter.  The custodian’s vacuum was not much better.  Thankfully one mentor lives really close to the school–her vacuum sucked the best!broilingWe put the plastic into the oven which had been set to broil.  We watched as the plastic went wavy, then flat.  When it is flat, it is ready to go.heatingThe vacuum was turned on, the mold was placed on the vacuum box, and the plastic sheet overturned on top of it all.  Using oven mitts and a heat gun we massaged the plastic in place around the mold.  There’s a bit of a learning curve with this process.  Sometimes there are holes.  After our 4th try we got a really good one!coolingWe chilled it in the fridge to cool it down a bit.doneThen we removed the plastic from the frame and took the mold out and cut around our shape to reveal the coolest chain guard ever!packingWe’re taking our vacuum forming supplies and our robot shooter to Transformix tomorrow to keep working.

Day 16: Smiles All Around

Day 16:  We got lots of great news today!  Our machine shop scheduling issues have been resolved!  Thanks to Transformix Engineering and McLaughlin Hall at Queen’s University!smilesOur orders have been coming in so we’re unpacking boxes, and moving forward with our plans.  The biggest excitement came when boxes of electrical components were unpacked.

A Tweedle in a Trap!

We worked hard to modify some of our robot structure and try some new ideas.  There are some creative ideas that we’ve been working on.  Look at this…we even smile while we’re sawing!prototypePart way through our work session today we took a time out to learn about talking with the public, particularly to judges and to the media.  We are lucky that CKWS TV, our local TV station is interested in following us through build season, checking in from time to time, watching our robot grow and develop, and watching us come together as a team.

workshopWe look forward to the opportunity to share FIRST Robotics with the rest of Kingston!

Day 15: Good News and Bad News

The Good News: We got our new hoodies tonight, and we all love them!   Thanks to Primetime Custom for doing such a good job on them yet again.hoodiesSome of our mentors are working very hard on their knitting. knittingThis season we’re knitting little hats to be give-away buttons for competitions. We’re known for our hats!dinnerWe had a wonderful ham supper from Jan and Ann tonight, and some special treats for Chinese New Year! Chinese New YearAfter dinner, we got right back to work.  Some of us are trying to get the camera code to work properly.programmersOur Chairman’s video is really starting to take shape. chairman's…and we had a great session to edit our Chairman’s essay.Chairman'sPlenty of us are working on the very confusing bumper math. bumper mathWe’re trying to make reversible bumpers again this year, but in a slightly different configuration.  It’s a pretty good math problem!  We did lots of research today, and called different stores to source fabric and white Sharpie markers.no fun zoneLots of work got done in the “no fun zone” today! The “no fun zone” is a quiet place for things like CAD to be finished without any disruptions.  By the end of the evening we got our CAD drawings ready for machining!prototypingOur prototyping team is looking at various ways to manipulate the bridge.  We’re coming up with some good ideas!  It helps to work with such a big creative group.what's this?For those of us who are in the know…this picture marks a rather momentous occasion.  We’re starting to work on the next part.what's this?Lots of us are tired out from long hours at robotics.nap timeNap time is much more comfy with bumpers as pillows!

The Bad News: We’ve got a potential hiccup with our machining that’s causing us a great deal of stress. We also have not yet received our metal shipment. Time is ticking by, and we’re crossing our fingers that it will all work out ok. We made cookies tonight to be delivered with our part drawings to the machinists.fun with bakingWe made LOTS of cookies!

We work tomorrow until 7PM.  Come ready to do lots of work, we’re a bit behind schedule!

Day 14: Prototypes and Discoveries

Day 14: Our morning started off with a fun game of “name the battery”.  We decided on some good ones like “Sparky” and “Tristan”.

naming batteries

We had another birthday to celebrate today!  Our tiara is certainly getting a lot of use.

Our bridge was balanced by adding surgical tubing.bridge

We’re now able to test balancing in more realistic conditions.  We started testing some of our sensors on the bridge today.

We looked at how to control the ball, and came up with a pretty good system.

electrical box

We had a look at last year’s electrical box, and decided how to make changes for this year.test chassisThe test chassis got used again by our programmers to test some code.

To help with more prototyping, we had a look through our scrap metal.  Our quest for the keyed shaft was unsuccessful.  “Would the steel shaft sink to the bottom of the pile because it is more dense?” -Mr. Wood

brainstorming

We were able to brainstorm anyway, and the ideas were flowing!

As time goes by, we are progressing with our robot designs, our game strategies, and problem solving.  We’re also learning more about our team mates and our mentors….we’re becoming more tight knit with each day.

We work Monday until 10PM.  Be there!

 

Day 4: Prototype testing and decision making

Work started today at lunch time for some!  Our goal of getting a prototype robot to traverse the barrier had a deadline of 6PM, and we were determined to make that happen.

lunch time

After school, we got some more wood for our field construction team…..

lumber

…we’ve made great headway on backboards and are ready to assemble a barrier and bridge over the next few days.  Our goal is to have essential field pieces built soon so we can begin to test robot designs on them.field

Measure twice and cut once!  We’ve been doing a pretty careful job so far.

cad

Our CAD enthusiasts have completed the CAD of the field today!  We’re going to have so many more CAD jobs in the next week.  We will be preparing technical drawings of our final robot design and parts for fabrication.

test chassis

After a few hours of work this afternoon our simple chassis was driving.  Testing a chassis alone was not enough though.  We were curious about weight distribution and how tippy our robot might be.  test chassisWe decided to suspend a weight from a meter above our robot to mimic anything we might build up there, and then give it a try.  We installed plywood chain guards to keep us all safe.

After ramming our test robot into a few barriers to test how it tipped, it was looking a little worse for wear.

“The past 20 minutes completely trump all of my experiences in grade 7 and 8.” -Olivia, grade 8.a real thinker

Back to the drawing board we go….

drawing board

By the end of our meeting today we have made progress in deciding the key configuration of our robot.  Now begins the fun of designing the details.  You never know where ideas come from.  We prototype and experiment with some interesting and unconventional materials.

ideas

We had the first meeting of the Chairman’s video team.  We’re starting earlier this year to make sure that we get the footage that we need without a feeling of panic!

video meeting

We have started several top secret knitting projects this build season.  They include a lot of creative design, and incorporating technology in unconventional ways.

knittingSome of us spent a great deal of time doing calculations, doing research and gathering our materials.

"Didn't we design a better way to do this last year?"

We taught a few new members how to knit today.  When they were upset about making mistakes Paige had some good advice.  We think it applies to building robots too!

“You learn more sometimes from failing, than you do from doing things right” -Paige, grade 10

Every day we work hard to balance homework and robotics.  Sometimes that is best done alone…

…other times we gather to have group physics parties!

Tomorrow we meet from 2:45-10PM.  Dinner is provided.  See everyone there!

 

Super Top Secret Design Challenge

Our meeting this week was busy and productive.  We debriefed about our bottle drive experience, and plan to hold another one that is bigger and better in the spring–so parents….please save your empties for us!

Look who showed up today!  Remi….who is modelling our “Apron of Doom”–if you do not clean up, you must wear it! (here are some classic apron pictures)  Remi is working on putting together an order of hoodies.  Think about whether you are interested in purchasing a team hoodie this year.  Prices and designs will be coming your way soon!

remiWe discussed the plans for the FIRST LEGO league tournament, and Jr. FIRST LEGO League Expo that we’re hosting on December 3rd.  We look forward to lots of our K-Bots volunteering to help out with set up on December 2nd in the evening, and with the running of the event on December 3rd.  We’ll be hard at work by 8 until probably 5 or 6.  There’s lots of volunteer hours available!  There are many jobs for students to do, from helping with registration, being good tour guides of our school for all of the visiting teams, cooking a delicious pasta lunch for our judges, and even taking a turn being the blue bear to help lead cheering!  For more information please contact Christine.

CADOur group split up for rotations of CAD tutorial work–some of us are getting really good at the practical applications of CAD.

CAD superstar

Others are getting really good at the impractical applications of CAD.  Meet Geoffrey the dragon!  GeoffreyWe held a brainstorming rotation for Chairman’s report ideas, and activities we should engage in over the year to help our community and build up our team.  We also walked everyone through the STIMS registration and online consent forms for FIRST.  Students and parents both must complete the process for the permission forms to be complete.brainstorming

Our beta testers were busy getting Barbra Streisand (Kasey III) up and running, as an important beta-testing deadline is coming up next week.

betatestingThe remaining station was a super top secret design challenge. Groups had 30 minutes and a variety of materials (wheels, newspaper, straws, plastecine, skewers, cardboard, wood, screws, saws, measuring devices, and lots of tape) to construct a vehicle that was powered by a balloon that could travel the farthest down the school hallway.

During the 30 minutes, each group needed to plan, prototype, construct, test and modify their design, as well as demonstrate good communication and teamwork skills.

discussing building

Since each group worked in isolation, the vehicles produced were unique.  Some had wheels, some didn’t.  Some used an inflated balloon, others used it as a slingshot.

balloon on steroids

that balloon's on steroids!

slingshot

If the car breaks, and part of the car goes the farthest, it still counts....right?

the real car is Sam

The real car is Sam....the balloon is just the distraction!

no wheels

look mom--no wheels!

We all learned a lot during this challenge.  It’s important to use time wisely–to allow time for testing and modifications–to plan before building–and to bring spare parts to the competition.  We had lots of fun, even if the vehicles did not travel too far down the hallway!  This might be a challenge we’ll revisit in the future.

durable?

we'll work on durability of designs...

While We Wait For Metal

Day 14: We didn’t get our metal order here on time to do any machining today, but we put our weekend work day to good use getting ready for our build.  We made circuit board diagrams….

It’s so important to clean up when you’re using another person’s workspace.  We need to keep on good terms with our Food & Nutrition teachers, and our custodians when we’re here after hours.  We invited our custodians for lunch with us, and then we did a good job of cleaning all the dishes.

cleaning up

After lunch there were some discussions about what controls should be allocated to the driver, and which ones should go to the operator.

controller ideas

We’re still working on making our dead Tetrix motors go.  We had a new idea today about how to solder on a new lead.  We’re waiting on a resistor, and then we can test our “repair” job.  It will be nice to see if some of our minibot ideas work.  We’re getting good at imagining that they do!  While we worked we listened to the “One Hit Wonder Hour” thanks to our D.J.s The Tweedles!

soldering motor fix?

We’re working hard to help the Cyberfalcons get through some tricky parts of robot set-up.  One of their mentors came to visit today to get some things sorted out.  We wish them luck.  There are lots of hurdles for rookies to overcome in their first build season.

We’re glad to help out how we can.

The Adventures of the Tetrix Motor!

Day 13:

Today we did lots of work on our mini-bot!

Mini-bot building!

Ever wonder what the inside of a tetrix motor looks like and have been too scared to look inside?Scary Insides!

Well ours stopped working…..

One brain or two?

So the Tweedles -for testing and prototyping purposes only- attempted to solder the tetrix motor to fix it. Eventually they gave up, and instead….

Burnt out!

Opened them up!

While we wait for replacement motors prototyping for our minibot continues.

When asked : “What do we do now?”

We reply:

“We just imagine it working” – Wesley (Grade 10)

Along with our Mini-bot adventures, we welcomed two new members to our team! We are very impressed how they jumped right in helping with bumper planning and filming Webinars. Hard at Work!

We introduced the new members to The Rules of K-Botics! Simultaneously we discussed and revised the rules.

Some "serious" discussion

What sort of  robotics adventures did you have today?


Sorting The Trail-Mix

Day 8:  What a snowy day!  Thanks to all the K-Botics members and mentors who got to school and spent the day working so hard.  We’ve got a tower assembly built now.

towerBecause of our short ceilings, we cut the pole to fit in our classroom.  We have a longer pole that we can use in the hallway or when we get our warehouse/test area set up.

Our CAD team made great progress on our robot parts while our programming team spent time updating the firmware on the jaguars.  We still haven’t seen our test chassis move.  Monday will be the big day!

updating firmware

Can you guess what this is???

prototypePrototyping continues on minibot and manipulators for our host bot.

mentoringWe were pleased to have Richard from Transformix helping out today with wiring for our minibot designs.  There’s lots of math involved with figuring out proper circuitry.

solderingWe tried hooking up our new circuits, which involved a few soldering lessons.  Webinar writing continued throughout the day.  Over the next few days we will be loading them on Youtube and creating a webinar section on this site.

webinarWhat would you like to see in a webinar?

While our footage uploaded we got to see our mentor dissect a rubik’s cube.

rubik's cube

this is one way to solve it!

We also used our down time throughout the day to clean up and organize our workspace.  Have you noticed how there are often baggies or containers of nuts and bolts (aka metal trail-mix) that get tucked away in cupboards or on shelves?sorting the trail-mixSorting the “trail-mix” is never a favourite job, but if we all work together it gets done faster.  We needed to take stock this weekend so we can order new supplies on Monday.

sorting the trail-mixToday we were thrilled to have lots of parents visit us to see our progress.  Robotics is a family affair: feel free to come and visit any time!

parentsWe appreciate all the support, and the cookies and muffins that our families deliver to us!  There’s a meal sign up sheet by the lab door, we hope that we’ll get some families signing up to provide evening meals when we stay late.  Thanks to those who already have signed up!

We’re Climbing The Pole!

Day 7:

There’s only one month, one week, and one day until ship day!

The Transformix logo

After school today some of our members visited one of our sponsors; Transformix generously donated some sensors for our robot!  We appreciate how they help us with our robot every step of the way.  From attending our kick-off and brainstorming sessions, mentoring us and teaching us how to use their machine shop, helping us acquire a testing location, and cheering us on at competitions, they are some of our biggest fans.

One of our mentors was feeling under the weather today, but he was still here in spirit!

Our first Minibot prototype is coming along well, we’re hard at work designing and prototyping.  It has had a test drive up the pole with great success.

It’s better than I thought!” -Wesley (grade 10)

Team members standing around the design table

We’ve cut a pole for the minibot to climb.  It is shorter than regulation height, because we don’t have 10 foot high ceilings.  We are working together to build the tower base.  We appreciate the mentoring of our friend Mr. Firth who makes the trip from another school to spend time with us in the evenings.

Some team members assembling the base for the minibot tower

We’re already building a prototype drive system for our host bot.  We hope to drive it before we leave tonight.

We are using Autodesk Inventor to design our robot parts.  Using CAD is an important skill and we are lucky enough to have mentors who can teach our new members to use it.  We are also establishing naming conventions for our files so the part numbers on the drawings correspond to the part numbers on the pieces.  This will make assembly a smoother process. (see our guide for organizing machined parts)

As always, snacks are an important part of our long meetings.  Today one of our team grandmothers made us cupcakes!  They were very tasty, and we were sure to thank her with a special card.  It is important to thank the people that help us survive build season.  For ideas about what to write on thank you notes please see our guide.
