How many eyes can a robot has?

How does a robotics and programming class looks like in your mind? sitting in front of pc silently? or listen to teachers in a classroom. No, the coding and robotics is never away from our life and all the theories of coding are actually based on real life situations. That is the reason in our coding class, we spend a lot of time in playing different games to simulate the robot's thinking. That is why when I ask our learners how many eyes are there in a robot? it pops up so many answers with so many stories. Coding is very a boring stuff, but fun with our life story......
