Insect form and function: how insects are constructed and how they work - Robotic engineers are making small robotic creatures modeled after insects - Almost 1,000,000,000 described insect species, probably 3,000,000,000 species in existence - Members of Arthropoda (spiders, crabs, trilobites, millipedes and insects) – jointed legged creatures Hexapoda – terrestrial crabs with adaptations for survival in dry habitats o Exoskeleton composed of chitin (sugar molecule, not solid when on its own) and protein Insect cuticle is like plywood – multilayered, laminated, glued together, flexible to bending yet resistant to breakage A rigid exoskeleton requires molting to grow Barrier between inside and outside of their body o Insect sensory organs Insect compound eyes and ocelli Insect sensillae Insect ears (different locations) o Abdomen (organs are located here) No legs Region can expand Tool to deposit eggs in specific locations o Thorax (locomotion – legs and wings)
