LEGO helper arm

My second idea is a LEGO technic based grabber arm to assist those with mobility issues in their hands/ arms. 

This arm could help people with many different tasks. Turning pages in books, grabbing items, finding things.  With some smart programming, it could even help with eating, brushing teeth, writing letters/ emails. 

I think the arm would be very helpful for people and would also be really fun to build and play with.
