It’s time to design the number one best robot ever! Anyone can make a suggestion, from x-ray lasers that shoot holes in the moon, to a diaper-changer attachment, to an index of a million knock-knock jokes. Please, just one addition per post.
Here’s my first idea: Arms and legs formed from branching manipulators, like in Harry Harrison’s The Turing Factor. Each arm (or leg) is a rod (made of some super-hard material, of course, like fictionite or unobtanium), which separates into three more rods of half the original’s length, and all are jointed halfway along. The separation continues on each smaller arm, down to microscopic size. This way, the arms can grasp any tool, or pick up tiny things, or be clustered together to be one big arm.
So, who’s up next?
