Why Raspberry Pi Computers?

Inside Erica will be a few Raspberry Pi computers which control things like cameras, ear motors, sounds, networking, lights etc. These were chosen because they have been specifically created for educational projects – and yet run all the software we need. It means the designs can be copied by people who want to try some electronics or computing – and they are very reasonably priced! We will be making hands-on teaching materials to go with each of the elements of Erica’s design. Each RPi will behave like a tiny web server and that is how they will interact – so the rhino really is like a small group of interacting web objects.
