Will is the youngest of the Robinson children. He is an electronics whiz capable of keeping the Robot well maintained and operating properly. One of Will's downfalls is his intense curiosity which frequently puts him in harm's way. Will is often unable to distinguish between good and evil, as evident by the large number of deviants with whom he seeks friendship. Will is both a trouble-maker and a hero. His reckless actions often endanger the entire Robinson family, while on the other hand, his common sense has saved lives on numerous occasions. Will is extremely loyal to his family, and has even developed strong friendship with Dr. Smith (who really doesn't deserve any such admiration). Despite Will’s age, he is able to confront the uncertainties of being marooned in space.
