Document Summary
Effectors manipulation: manipulators, used to move materials or parts, can manipulate large to micro objects, human arm usual model, two general parts, arm/body used to move materials within area, wrist, used to orient material. Increase chance of spotting predators: more eyes=more vigilance, decrease chance of getting captured, dilution effect, find a mate, many insects form mating swarms, sole purpose is to find a mate. Individuals always trying to increase gains and reduce risks: try to maximize food, escape from predators, and/or finding mates ii, no centralized control, the response of one individual is perpetuated because all individuals are trying to do the same thing b. Individuals in swarms are constantly moving as their internal states change: example with rolling locust swarm, feed until food runs out(cid:224)hungry locust(cid:224)food abundant, fish schools, hungrier fish are in the front (more dangerous, as they get enough food they move backwards to a safer position.
