So I know that for one of my final projects I will need to design something. A machine of sorts that helps someone. Basically the only criterion is that it has a power train. So my question is: What do people need? What do you do at work or at home and find yourself saying, "I wish someone would invent something to make this easier.." One example I am thinking of is some kind of lift that helps people who live alone that are confined to wheelchairs with getting in and out of the bath tub (though many probably have custom showers, but that's beside the point ) So what do you think should be invented?
