Project development idea

Nowadays, technology is getting better more and more, so we can use this technology to solve real problems.
I start thinking about my entournment and how i can solve some of the problems that surround me.
One of the things i found really interesting and usefull as engineer it's to create exoskeleton for people that is not able to walk or maybe to help people that have to learn again how to walk.
I still have to develop more this idea.
