Who does what?

Good job last week, folks.  We saw good teamwork on the "Build an animal shelter from newspaper" assignment that Helen gave you.  We also  completed another mission, the Animal Conservation mission worth 20 points, so we've moved it to the "Completed" column of our Kanban chart.

We also made progress on our model African Serengeti.  Tara and Macy got Google satellite images of the Serengeti and fitted them to our vibrating football table.  Nick, Alyssa and Lais then took several pictures from above the table, pretending the camera was a plane flying over the ground below.  They then used Autostitch, a program we used last year to fit microscope pictures together, to create a single bigger picture of the whole table:

With that job done we took pictures of Nick and stitched them together into a single bigger picture that I'm calling Nickenstein (this week's word).

The ability to put together small pictures into one big one will help us take closeup picture of animals and put them together into a picture of the whole area they cover.

Also last week we put together a list of jobs that needed to be done for our project and they included:
a) Fly the drone
b) Take pictures
c) Fit the pictures together
d) Train the computer to recognize the pictures
e) Count the animals in the pictures
f) Get pictures of model animals

You each voted for the top two things you might want to do and based on those votes we matched people to jobs.  One thing we discovered since last week is that if you want to fly a drone for anything but the fun of it (and doing research in a school doesn't count as fun even if it is) then you have to be 18 years old.  What that means is that flying the drone over a farm to take pictures of animals for our project can only be done by someone who's 18 or older.  On the other hand, you can all fly the drone for fun, so that's what we're going to do.  Let's hope for good weather at the end of the week!

Back to the jobs.  With flying the drone for research not one of the choices any more, we divided things up as follows:
a) Fly the drone for fun: Everybody
b) Take pictures: Neshaya and Lais
c) Fit the pictures together: Lily and Lais
d) Train computer: Lily, Alyssa and Olivia
e) Count animals: Olivia and Hannah
f) Get pictures of model animals: Nick, Tara and Macy

Also, Alyssa volunteered to do another important task

g) Investigate regulations around flying drones: Alyssa

As we mentioned last week, one of the researchers Olivia emailed answered her back and was super helpful.  He said:

Dear Olivia and the comet warriors,

Thanks for your email - it's great that you're trying to solve this problem. I put a folder in dropbox with some images from the wildebeest survey. The link to the folder is here (let me know if this doesn't work) - 

https://www.dropbox.com/sh/0r9dp6kmp667mmd/AAB0rBmKP2Tvz7HqpjHXZQbra?dl=0

There's also a blog article about how they perform the survey here - 

https://fzs.org/en/projects/serengeti-conservation/news-serengeti/count-wildebeest-serengeti-ecosystem/

The person who wrote that blog is Bryna Griffin, her email is bryna.griffin@fzs.org, and she might be able to provide you with more images of different animals and will probably be really interested in your research.

I should warn you I think what you're trying to do will be difficult. If you look at Fig. 2B in my paper you'll see that even people struggle to accurately count the wildebeest in these images! In my opinion the best way to improve the process is to focus on getting better information about the shape of the animal. You could do this by using a stereo camera or another technique known as structure from motion (https://en.wikipedia.org/wiki/Structure_from_motion). 

We've been trying to do this with a drone and testing it with cows too - I put some images from our tests in the dropbox folder. There's two images of cows taken at slightly different angles (im1.png and im2.png) and the height.png image shows the height of the cows by calculating the difference in movement of the pixels. 

I hope this helps with your project but feel free to ask me any more questions

Good luck

Please take a look at Bryna's blog post on counting wildebeest (https://fzs.org/en/projects/serengeti-conservation/news-serengeti/count-wildebeest-serengeti-ecosystem/) and see what questions we might have for her.

Fundraising and Mission Progress

Congratulations Comet Warriors on a successful yard sale on Saturday!  We raised $230 and got rid of a lot of junk at the same time.  It involved a lot of work sorting, selling, serving, and then cleaning up, so thanks to all those who participated.

We also made some good progress on our robot missions.  Olivia and Lily built an attachment to solve five different missions  - namely transporting the dog trainer to the research area, moving the veterinarian to the research area, doing the animal exchange, retrieving the seal-mounted camera, and putting the gecko on the wall.  Nick, Lais, and Alyssa then programmed it to do the Biomimicry mission,

Last week we made good progress on our seeing-eye dog mission.  Olivia built a robot cart to help the robot get over the gate.  We then tried to program it to complete the mission and got it to work once.  Now we just need to make it reliable!

On the project Olivia and Lily worked to get pictures of our toy animals for training vision systems.  Below is a shot of Daisy (the word for the week) from above.

 Tara and Macy worked with the electronic football table to develop a simulation of animals wandering around a field.

Our hope is that if we can train the vision system what toy animals look like, and have it identify them wandering on a toy football field, then we can work up to having it identify real animals in real fields.  To make that work we need to find some farm animals we can take pictures of, preferably by flying our drone over their field.  Does anyone know anyone who has cows or horses?  Hopefully lots of them?

Project Selection and Mission Progress

Last week we selected a topic for our project.  We had narrowed the choices to Wildlife Counting, Bee Colony Collapse, and Spectacled Bears.  It was great to see that numerous people had done some detailed research on the topics.  After some excellent presentations we voted to see which project we would do.  The vote couldn't have been closer, with Wildlife Counting coming out ahead of Bee Colony Collapse by 5 to 4.

In researching this topic, Olivia emailed the President of the Wildlife Conservation Network and asked him a few questions:

Dear Mr. Knowles,

    My name is Olivia O'Driscoll and I'm emailing you on behalf of my Lego Robotics Team.  This year we (and 70,000 other teams) are working on finding ways to improve human-animal interactions.  We spent a lot of time looking at the WCN website and talking to people in conservation and think we have an idea.  We're hoping that you could give us your thoughts on whether it would be worthwhile.

    A basic problem in conservation seems to be figuring out which species need help and whether the help they get is working.  Answering these questions requires knowing how many of a species exist and whether the number is growing or shrinking.  One paper we saw said "Accurate and on-demand animal population counts are the holy grail for wildlife conservation organizations throughout the world because they enable fast and responsive adaptive management policies." (http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0156342)

    The people who wrote that paper came up with a way to count wildebeest in aerial photos.  They say it works pretty well, but still needs some improvement.  We think we might be able improve on it. 

    Since those people are scientists instead of conservationists we thought we should check with you before getting too excited.  We're hoping you could answer a couple of questions for us:

1) Do you think this is a problem worth working on?

2) Are there solutions that are already good enough and cheap enough?

3) Are there obstacles to getting solutions adopted even if they work?

    We know you're super busy but if you could give us any insights on this problem, or any others you think would be working on we'd really appreciate it.  Thanks!

-- Olivia and the Comet Warriors

He kindly got back to us and anwwered:

Dear Olivia and the Comet Warriors,

Thank you for your email and thanks for your commitment to wildlife conservation.  I apologize for the slow response as I've been traveling.

Before answering your questions I wanted to qualify that I'm not a conservation biologist nor have I done any of this work in the field.  I do support this type of work and my 22 years working in this space does give me a broad perspective.

So, to answer your questions:

1) Do you think this is a problem worth working on?

Yes.  In order to affect any type of change one must be able to measure the system before you take action and after the action is completed.  Counting is expensive, time consuming, and inaccurate. For example, Paul Allen spent $6 million counting elephants and the results took three years to come out, however, the results of those data are defining conservation actions across Africa for elephants.

A less expensive, more accurate way of counting animals would be of great value.

2) Are there solutions that are already good enough and cheap enough?

There are a host of solutions and you can probably find a number online.  They include, for example:

a) Aerial counting from planes

b) Using camera traps to see what walks by

c) Collecting scat (poop) and doing DNA analysis to figure our how many unique animals it represents and then using statistics to estimate populations.

d) Putting up "hair combs" on trees and then putting scent on them so cats (Canadian lynx, mountain lions, etc) rub them and then analyzing the hairs.

These solutions range widely in their cost and the value of the data.  Sometimes you only want to know if the animal exists at all.  Sometimes you want to know if there are "some, many, or a lot" of the species.  Sometimes, like with the Amur leopard, of which there are only 32, you want to know EXACTLY how many there are.

Some of the methods are good enough and cheap enough.  Many are not.

3) Are there obstacles to getting solutions adopted even if they work?

Yes, there are many obstacles.  Scientists can be set in their ways and have strong egos about how things are done.  Cost is always a consideration.  Using the same method over a long period of time is important so you can compare to previous results.  However, if there is a better and less expensive way to do this it would be eventually adopted and used widely for the great benefit of wildlife conservation.

I hope this is helpful.  I'm excited to learn more about your idea and if we can make it happen.

All the best,

Charlie

This should give us a starting point on our research, and an idea of what kinds of animals we might count and how accurate we need to be.  We'll talk more about this this week, and the word for the week is "Charlie".

An example problem would be to figure out how many zebras are in this picture:

We also worked on our robot missions.  For several missions we tried this approach:

1) See if we can do the mission with our hand.

2) See if we can design a robot attachment to do what we did with our hand.

3) See if we can attach the attachment to the robot and do the mission by pushing the robot.

4) (For this week) see if we can program the robot to move the way we pushed it.

See you all on Thursday!

Missions and Priorities

Last week we worked on developing a strategy for accomplishing our robot missions.  We looked at all of the missions based on how hard we thought they would be to complete, and how many point they were worth. We did this by: a) Dividing the group into pairs and assigning each pair a set of two missions. b) Having each pair think hard about how they would get a robot to do each of the two missions. c) Deciding whether the mission would be Easy, Medium, or Hard to complete. We then gave all the easy missions a score of 3, the medium missions a score of 2, and the hard missions a score of 1. We then looked at the points awarded for accomplishing each mission.  If the number of points was 10 or less we gave the mission a score of 1.  If it was more than 10 but less than or equal to 20 we gave it a score of 2. If it was worth more than 20 we gave it a 3. We then combined the scores to give a priority, with 6 being the highest priority possible (easy and lots of points) and 2 being the lowest priority (hard and not worth many points.)  This gave us a list as follows: Mission Pts Pts Score* Diff Diff Score* Overall Score Shark Shipment 27 3 Easy 3 6 All Samples 35 3 Easy 2 5 Beekeeping 15 2 Easy 2.5 4.5 Feeding 80 3 Medium 1.5 4.5 Camera Recovery 15 2 Medium 2 4 Training and Research 27 3 Medium 1 4 Biomimicry 15 2 Medium 2 4 Milking Automation 15 2 Medium 2 4 Panda Release 10 2 Medium 2 4 Seal in Base 1 1 Easy 3 4 Milk in Base 1 1 Medium 3 4 Milk on Ramp 4 1 Medium 2.5 3.5 Animal Conservation 20 2 Medium 1.5 3.5 Prosthesis 15 1 Medium 2 3 Service Dog 15 1 Medium 2 3 Clearly the Shark Shipment is the mission to start with.  Olivia and Lily had written a program last week to do the shark mission, but it wasn't as reliable as we would like.  Nick, Neshaya, Lais and Alyssa worked some more on adjusting the speed and alignment and got it to work five times in a row.  Yay!  (And Yay is the secret word for this week.) Tara, Macy and Hannah got the Animal Exchange mission model pretty much completed so we have what we need to try all the missions now. Also last week we talked more about possible research projects and narrowed the choices down to: a) Bees and colony collapse b) Animal counting c) Spectacled bears. Those interested in each possible topic should come this week with whatever research they could do over the past two weeks.  Each person or group interested in a topic can present the problem that interests them, and the possible innovation that would help solve that problem.  After the presentations we'll vote on which project the team should do.

Teamwork, Mission Models, and Project Ideas

Today we did four things:

1) Homework review.  Most people had read the blog and watched the video, and Neshaya won the draw for the homework prize.  Congratulations, Neshaya!

2) Worked on defining what a team is, does, sounds like, and does not do.  We then tried to use what we learned in a teamwork exercise.  The exercise was to get the gummy worm through the gummy ring and into the plastic cup using nothing but paperclips.  The idea was to work  in teams of two and find the best way to solve the problem.

3) Built several of the mission models for this year's competition.  Congratulations to Alyssa, Lais, Hannah, Nick, and Neshaya.

4) Programmed the Shark Transport mission.  Congratulations Tara, Macy, Lily, and Olivia!

Homework for Monday:

Pick an animal and think about how it interacts with humans.  Hopefully you did this last week. What's new for this week is to talk to an expert about how those interactions might be improved.  For example, dogs' natural instinct is protect their owners and their property, which is part of the reason some people own them.  Their instinct, unfortunately, leads them to attack mail carriers, or to run into the road to bark at cars and get run over.  Is there a way their interactions with mail carriers and cars could be improved?  The secret word for next week, by the way, is Molly, which is the most common female dog name in the English language.

Ecole Catholique Cathedrale FLL 2016

Welcome back, Comets!  We've got a lot of work to do this season and not a lot of time to do it. The competition will be held November 19 at Duncan MacArthur Hall (Queen's West Campus).

We'll be using this blog again this season to keep you informed about news, tips, progress, dates, and so on during the season.  Please check back regularly to make sure you get all the necessary information!  Each week there will be a secret word contained in the week's blog post.  Please show up each week knowing the secret word for the week.  The word for this week is Flipper (a TV dolphin who helps people.)

Remember that the First Lego League competition consists of three main parts: 1) core values, 2) the project, and 3) the game.  The core values define how we work together as a team, and how we interact with other teams.  The project is a team research effort in a specific area, with the team required to develop and share a solution to a particular problem.  The game involves the design of a robot to complete as many missions as possible on a specially designed board.

Most participants find the robot component the most fun, but remember that the overall score is based on all three components, with each counting for roughly one third.  Your robot could complete every mission in the game successfully and your team could still finish last overall if you don't do well on the project and don't demonstrate the core values.

To get up to speed quickly on the core values, the project and the game, please check out the videos below:

Congratulations, Comet Warriors!

The Comets had a great tournament at MacArthur Hall yesterday!  It was a long day, from 7:45am until 4:30pm and despite some ups and down things went very well overall.  After three very well done presentations things started going downhill as the robot didn't really want to perform.

Comet Warriors

The team pulled together, however, and worked through the problems one round at a time.  They ended with a tournament-high score of 458, giving them the Robot Performance award.  In addition they won first prize for their research project.  They'll be off to the provincial championships in Oshawa on Jan. 16th.  Congratulations!
