Challenges
Look around your home. There will be automatic machines with many of the features of robots in them. Take a common household machine and look at its inputs and outputs. Use these to make a diagram, showing them going in or out of a controller. Think about how they will move, if they move around the house.Consider further what sensors and feedback loops may be present in this system. What is it monitoring? How is it responding to that information? How would you use sensors like these in a robot?
