Meeting Abstract 59.1  Friday, Jan. 6   Muscle properties are tuned to mechanical function: lessons from hopping toads AZIZI, E; Univ. of California, Irvine eazizi@uci.edu Variation in the basic properties of muscles has likely been shaped by the mechanical tasks muscles perform. However, most muscles cannot be easily fit into a functional category and often perform a […]

Meeting Abstract 59.5  Friday, Jan. 6  Jump racing: do horses slow down due to a force limit? SELF, ZT*; SPENCE, AJ; WILSON, AM; The Royal Veterinary College; The Royal Veterinary College; The Royal Veterinary College zself@rvc.ac.uk Running animals face the challenge of using limb force to support body weight over the time in which their feet are […]

Meeting Abstract 59.4  Friday, Jan. 6  Extrinsic loading in Cuban tree frog jumping ABBOTT, EM*; AZIZI, M; ROBERTS, TJ; Univ. of California, Irvine; Univ. of California, Irvine; Brown University emily.m.abbott@gmail.com It is common for locomoting animals to bear additional loads. It may occur naturally, as with gravidity or large feeding events, or artificially, such as with any […]

Meeting Abstract 58.2  Thursday, Jan. 5  Understanding undulatory locomotion in fishes using an inertia-compensated flapping foil robotic device WEN, Li*; LAUDER, G.; Harvard University; Harvard University liwen@oeb.harvard.edu Recent advances in understanding fish locomotion with robotic devices have included the use of flapping foil robots that are self-propelled and in which the thrust forces during swimming average to […]

Meeting Abstract 58.6  Thursday, Jan. 5  Towards a terramechanics for legged locomotion on granular media LI, Chen*; GOLDMAN, Daniel I.; Georgia Tech; Georgia Tech chen.li@gatech.edu During locomotion on sand, animals and robot models interact with granular substrates to generate thrust and lift. While resistance forces on simple shapes like discs and plates during intrusion along vertical or […]

Meeting Abstract 58.3  Thursday, Jan. 5  Legged locomotion of a bio-inspired lightweight robot on granular media QIAN, F*; ZHANG, T; LI, C; SHEN, J; HOOVER, A.M.; BIRKMEYER, P; PULLIN, A; FEARING, R.S.; GOLDMAN, D.I.; MASARATI, P.; Georgia Institute of Technology; Georgia Institute of Technology; Georgia Institute of Technology; Georgia Institute of Technology; F.

Meeting Abstract 58.1  Thursday, Jan. 5  Hydrodynamic function of shark skin and two biomimetic models LAUDER, G. V.*; OEFFNER, J.; Harvard University; Harvard University glauder@oeb.harvard.edu It has long been suspected that the denticles on shark skin reduce hydrodynamic drag during locomotion, and a number of man-made materials have been produced that purport to use shark skin-like surface […]

Meeting Abstract 58.5  Thursday, Jan. 5  Exploring the parameter space for Kármán gaiting: kinematics across speed and size LIAO, James C.*; TAGUCHI, Masashige; Whitney Lab, Univ. of Florida, Gainesville; Whitney Lab, Univ. of Florida, Gainesville jliao@whitney.ufl.edu Very little is known about how swimming fish relate to turbulence. We measured the body kinematics of 12.1 ± 0.4 cm […]

Meeting Abstract 58.4  Thursday, Jan. 5  Disturbed ground leads to failure in a sea turtle inspired robot MAZOUCHOVA, Nicole*; GOLDMAN, Daniel; Georgia Institute of Technology; Georgia Institute of Technology nmazouch@gatech.edu Animals like sea turtles that must locomote at the water-land interface use flippers for swimming in water and crawling on a sandy beach environment. To reveal locomotor […]

Meeting Abstract 57.3  Thursday, Jan. 5  The relationship between insulin-like growth factor-1 and life history across Mammalia SWANSON, E.M.*; DANTZER, B.; Michigan State University; Michigan State University eliswanson@gmail.com Life history traits describe parameters associated with growth, reproduction and survival. Life history variation is a hallmark of biological diversity, yet persistent patterns of variation are apparent among life […]
