Explorers are designed to appeal to all readers aged 6--8: those who are just starting to read alone and more confident readers who are beginning to exercise wider reading and cross-referencing skills. Lively, dramatic artwork scenes draw children into a subject, and each scene is followed by a photographic information spread that gives a wealth of extra detail. As a fun extra element, the reader can follow themed links to access information on related topics. Robots is an adventure into the fascinating world of robotics: how they work, the variety of jobs they can do and robot exploration underwater, in the air and in space.
