Adventure in the jungle

The hero by saving the world, and do not worry, it will happen. For this he goes in search of his personal robot (all humans have one, their image, and all the fond), on foot, on a primitive planet populated by indigenous and other forms of life, unpredictable and more or less crazy. The book is full of scientific nonsense, especially in medicine and physics, and the method used to save the world, revealed at the very end is completely stupid. However, if I've learned anything, I'm not bothered me, it's always something, and often quite funny!
