A new device that can diagnose illnesses quickly - a bit like Baymax from Big Hero 6 - is being developed in the USA.
At the moment, finding out what illness a patient has can often take weeks, so the new device could make healthcare quicker and easier.
If the device is approved for sale it could prove really useful in the developing world.
What would you invent to help people?
I think people should invent a door that when you walk through can sense illness, even if you did not know you had an illness.

I would make a robot that would help people at home.
