SMIB: Mission Cure

SMIB (Space Multitask Intelligent Bot) is a small and smart robot created by humans for critical missions. It can be sent to planets in diverse environments, being remotely monitored and controlled by operators on Earth.

Its current mission is the most important so far: a strange syndrome is threatening people all over planet Earth - they are not able to smile anymore!

Scientists have developed a formula that can be the cure. The problem is: its components can only be found in distant planets.
