Since we're going to be building robots soon, we had a fantastic guest speaker in to tell us all about how he does it. Martin Horspool builds amazing robots which he sells to people. He builds his robots out of things that have been thrown away. He showed us some of his cool robots and then explained how we could join different parts together to make our robots. He also answered heaps of questions for us so we're feeling almost ready to begin constructing our own robots!
