Computer simulated evolution of virtual creatures (1994)

"This narrated computer animation shows results from a research project involving simulated Darwinian evolutions of virtual block creatures. A population of several hundred creatures is created within a supercomputer, and each creature is tested for their ability to perform a given task, such the ability to swim in a simulated water environment. The successful survive, and their virtual genes containing coded instructions for their growth, are copied, combined, and mutated to make offspring for a new population. The new creatures are again tested, and some may be improvements on their parents. As this cycle of variation and selection continues, creatures with more and more successful behaviors can emerge.

The creatures shown are results the final products from many independent simulations in which they were selected for swimming, walking, jumping, following, and competing for control of a green cube."

Four-winged robot flies like a jellyfish

"Tiny flying robots usually mimic nature's flyers, like birds and insects–but perhaps that's due to a lack of imagination. A four–winged design created by Leif Ristroph and colleagues at New York University, which boasts a body plan reminiscent of a jellyfish, is more stable in the air than insect–like machines.

The prototype consists of a carbon–fibre frame surrounded by two pairs of thin plastic wings that open and close when driven by a motor. Its shape allows it to fly upright with little effort, without requiring sensors or intelligence to adjust its wings like those used by insects. 'Making a dumb machine is a nice strategy for very small robots,' says Ristroph. 'Without circuits and sensors, it's also lighter.'"
