    The wrist is highly flexible, allowing the wing to be folded down like an umbrella. In most bats only the thumb retains a claw, but in some flying foxes the 2nd digit has a small claw. The hindlimbs are rotated through 180º. Thus when a bat walks on the ground, its knees stick up into the air.

    2012-4-26 · The bat robot features a hybrid drive, partially actuated by a servo motor which drives the primary flapping motion, and SMA actuators (Migamotor nanomuscles ) which drive the morphing-wing motion. Here, we have focused on the latter, by: (i) implementing a robust control architecture that allows for an accurate SMA-muscle actuation, and (ii) validating through …

    At hovering and slow speed bats use a leading edge vortex to enhance the lift beyond that allowed by steady aerodynamics and an inverted wing during the upstroke to further aid weight support. The bat wing and its skeleton exhibit many features and control mechanisms that are presumed to improve flight performance.

    2 天前 · The wing membrane consists of two layers of skin, generally darkly pigmented and hairless, between which course blood vessels and nerves. When not fully extended, the wing skin is gathered into wrinkled folds by elastic connective tissue and muscle fibres. Some of the fingers, especially the third, fold over when the bat is not in flight; the wing may then be quite tightly folded or may partly enfold the bat…

    We expect the bat to try to avoid a slack membrane and find several features of the wing that may act to reduce or avoid slack. Within the plagiopatagium there are muscles unique to bats that originate on the skeleton and insert in the membrane ( Fig. 8 ) (e.g. MacAlister, 1872 ; Vaughan, 1959 , 1966 ; Norberg, 1970 , 1972b ).

    Heteropteran - Heteropteran - Wings: The texture of each of the two pairs of wings is distinct in heteropterans. The mesothoracic or forewings (called hemelytra, elytra, or tegmina) are stiff and have an oblique line that abruptly separates the leathery basal half from the membranous apical half, while the metathoracic or hindwings are thin, delicate membranes. At rest the forewings are folded …
