A miniature robot that can crawl through you veigns and lungs to find a tumor and then zap it with drugs? People growing up in the 80’s will probably think of the movie Innerspace. But the little iron bug you see on your left and below does all that. It can travel inside your body guided by electromagnetic fields outside your body which propell the tiny tentacles of the mini robot. I believe everthing is possible from now on. We probably are beaming up Scotties in some 20 years from now.
Innerspace never was fiction
