Ozobot in Code Club

Earlier this week (21st March 2016) the Ozobot Bit were used as an extra activity at a Code Code - they went down very well with the children. 

Using Ozoblocky (http://ozoblockly.com/editor) they just played with making a short routine on a PC and download it to the ozobot.

Some very anecdotal observations:
- It would probably be better running this on tablet rather than a PC. There is nothing wrong with the software, but holding a bot against a screen, even one as light as ozobots, gets a bit tiring. If it was on a screen flat on the desk there wouldn't be a need to hold it. It is obvious with hindsight.
- Though movement was a big attraction for the children, the flashing light patterns seem to be, for the groups who work on it, a bigger attraction.
- The transition in moving from Scratch to Blockly was relatively smooth.

They all asked can they have the next session being solely about using robots.

As the author of this blog, I am clearly positively biased to physical computing - but the engagement, even from the more reticent children, was quite high with these.

Playing with Ozobot Bit and Blockly

Previously I discussed the older Ozobot that were programmed by colours on paper or made to dance via an App. The newer Ozobot Bit still can be used in these ways but also can be programmed using a Blockly web-based interface at http://ozoblockly.com/editor, so are now programmable on tablets, but also PC, Macs, essentially anything that can run the webpage.



First stage is the calibration of the 'bot'
1. Hold the power button on the ozobot until it starts flashing with a white light.
2. Move to the white space that is similar to the bottom of the Ozobot, the wheels might start moving but as you get closer to the space they should stop.
3. The Ozobot should start flashing green - that is ok continue holding the ozobot to the screen until it stops flashing green - if it flashes red start again.

Build your code blocks and when you are ready press the power button on the Ozobot. Hold the ozobot against the white space again and holding it there press the load button. The white space should now be flashing different colours, but the ozobot should be flashing green programming the ozobot.

Now to run them press the power button twice. I have add a two second delay in the code so I can get my hands out of the way before they start moving. The video below shows two of them so through this routine twice
- 2 second delay;
- Zigzag a little
- Flash the lights through the rainbow colours;
- Move in an arc;
- Flash the lights a bit like fireworks going off



It is relatively easy to program these and fun, but you may have to hold the Ozobot to the screen for a while if you use a Mac or PC. They are cute and the flashing LEDs offers some interesting effects like the 'fireworks'.

Ramblings about Social Robotics in Schools

Sometimes what I do as job can have some major personal pluses (I get to play with robots some of the time), one of these has been the opportunity to introduce people to social robots, and recently I have been lucky enough to managed to do this four times-  twice to my own computing students, but also to groups of primary school children in two events (see below). 

Apart from it's what I enjoyed doing; the social robots we are starting to see are great, but there is so much more that could be done. Who is going to develop this - possibly one of these children? Why not? It has taken nearly 40 years to get from R2D2 on the screen to some of the social robots we are seeing launched now, in another 40 years we might have something as bright as R2D2 (R2D2 was always brighter than C3PO). Why wouldn't one or more of these bright children or one of the students I teach, be the ones to contribute to this? They have the enthusiasm, with the changes in the National Curriculum in the UK they are developing some of the skills and asking the questions. Look at the work that work being done by Pi Foundation, the CamJam EduKit 3 robot kit (http://camjam.me/?page_id=1035) and especially products such as the OhBot (see bottom of the post for details of this robot) as just as a few examples of how this is being developed.



Event 1.

In an in-reach STEAM activity day I have had the opportunity to show off two NAO robots in action to a group of 8-years olds. As well presenting a short presentation on social robots (see below). By the way Red and Smurf are the nicknames for the two robots.

Event 2. 

A talk on Social Robotics (with a little help from a Red friend) to an audience of primary school children as part of Lab_13's Lectures at Wollaston School, Northamptonshire. 

Red performed, walking with three of the children and the presentation included discussion about the robots JIBO and Buddy that are expected this year.

Changes need to the presentation

A change I would like to make is to bring along an OhBot (a bit like the one in the video below) as well as including OhBot in the revised presentation slides.

ozobot - cute, fun and colour-mad

I have had these for a while, a couple of Ozobots. Small little robots that react to colours on the ground. Below are figures showing the Ozobots working with an App Ozogroove which allows the bots to perform dance routines, and out of the box, they are set up to run around a track that has coloured blocks causing the bots to change what they do.

figure 1.

 Interesting thing about these is the way a routine is transferred from the App to the bot. - by flashing light. In figure 1 the two ozobots are mid way through being programmed with a dance routine. Figure 2 shows one of the bots during the dance.

figure 2

The latest version these, Ozobot Bit 2.0 can be programmed via Blockly-based website with light being used to transfer the routine. I had a play with one a couple of days ago, liked it so much I order a pair from Amazon!

As an aside, when I first saw the light transfer method it reminded me of some of the early British TV programmes on Computing in the 1980s, who used a system where a flashing cursor on the screen was used to send data to be recorded on cassette or into the computer.

I would be interested in finding out what else has or can be done with these interesting little robots. If you have any ideas or experience with them please free to add comments.

So small robots and Raspberry Pi, which I was hoping for as they are my interests as well.



The audience based on pages views is an interesting mix and not really sure what to make of it, apart from I hope they are all finding it useful.
