MEMS robots 100x smaller

Each microrobot is shaped something like a spatula but with dimensions measuring just microns, or millionths of a meter. They are almost 100x smaller than any previous robotic designs of their kind and weigh even less. The devices are about 60 microns wide, 250 microns long and 10 microns high that each run off power scavenged from an electrified surface. Propelling themselves across such surfaces in an inchworm-like fashion impelled by a “scratch-drive” motion actuator, the microrobots advance in steps only 10 to 20 billionths of a meter each, but repeated as often as 20000x a second.

choco-nano bots can’t be far off. hmm chocolate!

NYC Tourist Etiquette

  • DO NOT DRESS ALIKE.
  • Watch out for DELIVERY and MESSENGER BIKES!
  • DO NOT DO THE FOLLOWING: Walk 4 abreast holding hands; Congregate around busy street corners, hang around stairways or active doorways; Do not clutter up Grand Central Station during rush-hour (8-9 and 17-18) — it’s much nicer around 11;
  • Hey Buddy! Get outta the way! Despite the above, let me remind you that this is a working city. This is not like Washington, DC, or Las Vegas — places that are artificially supported by the hard work of fools from other cities.
