When the little robot "Pyramid Rover" struggled to climb up the 64-meter-long "South Passage" alone, this 90-minute lonely journey seemed extremely long, just like the life of this dim martyrdom. The true meaning of the Arabic proverb, "A man is afraid of time, and time is afraid of the pyramid" is undoubtedly at this moment. This passage is intended to emphasize:. ['The climbing process of the small robot is very slow.', 'The traffic conditions on the pyramid "Southern Road" are very bad.', 'Arabs fully understand the characteristics of the pyramid.', 'Pyramids climbed by little robots have a long history.']
