what is the predator of a praying mantis Mantises are generalist predators of arthropods what family or species is this a part of? Mantidae ("mantids") are there any fossils of this found? Yes, from Siberia do they display cannibalistic behavior? Yes, sexual cannibalism what happens in this situation? The female may begin feeding by biting off the male's head and if mating has begun, the male's movements may become even more vigorous in its delivery of sperm is there any biologist who has studied this species? Kristensen, Beier, Ehrmann, Klass to name a few what is the other species mentioned earlier that this species preys on? It is an invertebrate animal having an exoskeleton, a segmented body, and paired jointed appendages describe the segments of the body. The embryos of all arthropods are segmented, built from a series of repeated modules how is the insect mentioned earlier associated with robots? A prototype robot inspired by the forelegs of the praying mantis has front legs that allow the robot to walk, climb steps, and grasp objects

Robot [SEP] Introduction
A robot is a machine—especially one programmable by a computer— capable of carrying out a complex series of actions automatically. Robots can be guided by an external control device or the control may be embedded within. Robots may be constructed on the lines of human form, but most robots are machines designed to perform a task with no regard to their aesthetics. Robots can be autonomous or semi-autonomous and range from humanoids such as Honda's "Advanced Step in Innovative Mobility" (ASIMO) and TOSY's "TOSY Ping Pong Playing Robot" (TOPIO) to industrial robots, medical operating robots, patient assist robots, dog therapy robots, collectively programmed "swarm" robots, UAV drones such as General Atomics MQ-1 Predator, and even microscopic nano robots.
