Back in April I was lucky enough to spend a weekend at the Nao Dev Days in Paris. It was a great opportunity to meet other Nao developers and to see what everyone was doing. We also had a hackathon style event where we were challenged to create a working Nao behaviour over the course of the weekend. Well, I had a go and created a simple childrens game that helped them to learn to listen and taught some simple comprehension skills. Basically, the program allowed Nao to read the child a story and then asks them some questions about what they had just heard. The basic behaviour was completed during the event but I have subsequently been working on allowing people to add their own stories and generally tidying up the behaviour. Here is a video of the result.

Earlier this year we posted about some work we had been doing about interfacing I2C devices to Nao using an I2C to USB interface. This was primarily around the TPA81 thermal array sensor. Well, we have been developing this a little further.
Firstly, we decided that Nao should be able to carry the sensor when he needed it and produced a prototype Thermal Array Gun, using an old Band-Aid (plaster) box, a nerf gun dart, electrical tape and liberal amounts of hot glue. This is what we ended up with, a bit Heath Robinson but it works.
The unit houses the I2C to USB interface and then has the thermal array sensor mounted on the front, to allow correct reading of the ambient temperature. Internally, it is pretty simple:
The thermal array sensor provides an array of 8 spot temperatures and 1 ambient temperature. This allows us to locate a 'hot spot', within the arrays field of vision. In the example video below Nao has been programmed to look for 'hot spots' 5 degrees Celsius above the ambient temperature. He has also been programmed to avoid temperatures more than 30 degrees above the ambient temperature.

This is a bit off the beaten track for what we normally post about here at Alt-View but I loved it so much I had to post it.
This is, most definitely, how all science should be taught. With flair, showmanship and making it engaging. Top Marks to Dr Roy Lowry, you are a Rock God of Science.
