Exploration is a risky business. Advances in technology now mean that in many situations we can send machines to explore, rather than risk human lives. Among other amazing feats, robot explorers can climb into an active volcano, dive to the deepest point on Earth and travel to the dwarf planet Pluto. In this book, aimed at children aged 8+, readers can meet these robot explorers and many more, then try a quick quiz to find out how much they have learned.
