1) Try moving forwards, backwards, sideways, upwards, downwards, spinning. What differences are there between the movements of a human and a robot?
2) Try walking on all fours at different speeds. Is it easy or difficult to move like this?
3) Try putting your right arm behind your back (use your left arm if you are left handed). Now try doing everyday tasks (writing, doing up a button, pushing large and small objects, tying your shoe laces). Why is it difficult to do these things?
