Connected Bumbles take 2012 Environmental "Internet of Things" Award

I'm thrilled to report that our bumblebees were voted by readers as the winner for the 2012 Internet of Things award in the Environmental category! This is a great end to a busy year with the bumblebees, where I installed a lot more technology to monitor their behaviours and environment.

I've created an explanatory page to help explain the relevance and benefits of the technology to our project.

It turned out that for the main colony (as widely reported) it was actually a pretty disastrous year. Foraging proved difficult with so much rain and we had a brood of about 20 early queens in April that all left the nest - none were produced over the summer.

One surviving queen did seem to have an attempt to build a second colony, but it was doomed as no workers emerged and her honey supplies were robbed by other bumblebees.

So, 2012 proved to be quite a different year to 2011, with no colony activity beyond August (November in 2011) - but with the added delights of a short spot in the BBC's Britain in a Day film and the IOT award to round things off!

Podcast Publicity

We're indebted to Hans at ioBridge for a great mention in a podcast by himself and his co-founder (Jason) over on "IT Conversations".

The discussion is about the "Internet of Things", it's relevance and evolution, and how ioBridge has contributed to that (particularly with some unique Intellectual Property).

ioBridge is the core technology we use to interface our bumblebee nest to the Internet and it has worked impeccably (and easily) since the day we installed it. Hans has been a great advocate for our project, which is arguably another "novel use" for their technology and a demonstration of not just connecting "things" to the internet, but connecting "Nature".

Our discussion is around 18 mins into the podcast. 

We've got some more great technology to come too, so watch this space.

The World's 1st Bumblebee Tweet?

For the first time, our bumblebees generated their own tweet this morning as a result of increased activity following the prolonged cold and rainy spells.

Our bumblebees' first ever tweet

To my knowledge, this is the first tweet ever generated by bumblebees themselves. Sadly they are not equipped with a bee-size keyboard, so instead the tweet comes courtesy of an activity monitor via the entrance flap to their nest. The flap itself is there for protection against invasion by Wax Moth and the bumblebees have learnt to operate it in order to leave the nest to forage. 

The Bumblbees are busy and have started tweeting

While the tweeting is fun, there is a serious point to having an "internet enabled" bumblebee nest, as we are collecting data about the environment/micro-climate and the bumblebee activity "outside of the laboratory". Though bumblebees have been studied for well over 100 years, some of this research takes place in the lab; a criticism that is often levelled, for example, on studies of the effect of pesticides on pollinators.

Our project, therefore, is demonstrating a proof of concept for the type of technology that can be used to study bumblebee behaviour in wild environments. We hope to build on the data we collected in 2011 which was able to determine the factors that trigger bumblebees to start and stop working at the beginning and end of the day.

Nest Sensor Setup (part 2)

I finally got out in the garden again to day to complete part 2 of my bumblebee sensor project.

The system has been up and running for a week, measuring temperature and light levels, but I needed to tackle two things:

1. The outdoor temperature sensor was too exposed and over-reading in direct sunlight; and was too close to the garage wall, so also picking up heat from the wall
2. I still had to finish constructing and fit a flap sensor to monitor activity in and out of the nest

For the thermometer, I hacked a small bottle apart and fixed it up with my new favourite "stuff for making things with": Sugru. Here is is below with the iobridge board in the background.

Flap Counter

Next up was the flap sensor. Getting a good flap sensor running has been critical for me this year, because I want to use it to closely correlate activity data with enivronment data. I was only able to do this last year in a minimal way because it's so labour intensive (to do from CCTV).

While this initial system will not give me the reliability required to accurately count bees in and out (it's not directional anyway) what it should do is give me activity levels throughout the day (e.g. first, last, flights during bad weather etc.) which will definitely be a step forward. 

The system is comprised, essentially, of an alumiumium foil strip attached to the side of the flap that acts as a make/break switch on the ioBridge digital input. When the flap is closed, the circuit is made, and the digital input is held low. Once a bee pushes through the flap, the circuit is broken, which generates a digital pulse that the ioBridge board can count. 

flap sensorIt's taken quite a bit of experimenation to get the inputs working in a way that is meaningful. Opening and closing the flap doesn't just generate a single pulse but can generate many (the bumblebees themselves very rarely just open it cleanly - but push against, causing it to open and close); so I can't rely on this basic circuit to count single open/close of the flap. 

But it doesn't really matter as the system will count the total number of activations and report this every 10 minutes. These 10 minutes slices will give an indication of the overall activity level, and in particular detect things like 1st & last exits, which I'm particularly interested in. 

This is only a phase 1 system - to get me started and get some data collected; I have ideas/plans for two further developments of this system - one using a light beam sensor (this would solve the problem of the flap being so busy that it actually gets held open and only counts a single pulse for many bees) and also a non-contact displacement sensor which will measure the exact angle of opening. Ideally a combination of these two would be good - but I don't have enough inputs at the moment. 

So, I have to wait for a few days now to collect some data and see how the system performs. 

Two much excitement for one day

Turned into an interesting day today with two bits of news.

Getting Sensitive

First of all I was contacted back by Zettlex - a small company in Cambridge who make "non contact" distance sensors. Their systems are very small and light, based on magnetic resonance, and can very accurately measure the distance between the sensor and an 'antenna' device attached to a moving object.

Now, before you go thinking I'm sticking sensors to bumblebees, I'm not! (That's next year's idea!) ☺ 

The plan, actually is to mount a sensor on the wax moth trap door, so that when it is in use (see below), the movement can be detected. 

bumblebee using the wax moth flapI wasn't sure if Zettlex would have been able to supply such a small, single unit, but they have very kindly offered to help me out - so the least I can do is sing their praises! 

Of course, there will be a lot of work still to get the sensor working, hopefully integrated with the iobridge platform so I can get realtime data and alerts out to the internet and beyond. I'm actually really excited about the possibilities, because over and above tracking simple activity data, such as start and end times of the day, I may be able to get data about how the flap is actually used: for example, how long it takes a bumblebee to master its usage. 

Hitting the screen

Even more exciting news came this afternoon with confirmation that some of our footage has made it into the final "Britain in a Day" film. I'm mentioning it here, because although we submitted several hours worth of material we know that the piece that has been selected concerns our bumblebees. It's actually a lovely segment, filled with emotion and despite its short length, a strong storyline and message; which is probably why it succeeded in being picked.

I don't want to give away too much, so that's all I say; but if you are in the UK, the film should be showing on BBC2 on June 2nd 2012. 

Here's some information about the whole "Britain in a day" project:

Britain In A Day is a major new project designed to capture a unique snapshot of Britain on one day, and people from all corners of the United Kingdom are invited to take part.

On Saturday November 12th we asked people in Britain to film something that captures the intimacy and singularity of their life and to upload it to a dedicated channel on YouTube. With the support of executive producers Ridley Scott and Academy Award winning Kevin Macdonald, director Morgan Matthews will use the rich trove of material submitted to craft a feature-length documentary film that captures the variety and vibrancy of life in Britain today. 

The result will be broadcast on BBC2 next year in the run up to the Olympics.

The idea is based on Life In A Day, the global, user-generated feature film produced by Ridley Scott’s company Scott Free London and directed by Kevin Macdonald. 80,000 videos were submitted to YouTube by people all over the world, wherever they were and whatever they were doing. The result was a powerful and inspiring portrait of the world on a single day. 

We feel privileged to have been selected and are really looking forward to seeing the whole film. If it turns out anything like "Life in a Day" (the original global version) it will be brilliant!
