Harvard stories

Harvard has successfully demonstrated a collective of quarter-sized robots that operate with "swarming" behaviors — such as formation, control and synchronization. Once activated, they are autonomous and do not require human interaction to control their activity.
You and I may consider it cheating, but Harvard's Robert Wood and his team have slapped a bunch of tiny actuators onto pieces of origami paper and have taught it to bend itself into different shapes. What could that even be good for, though?
