Animals can expend energy to acquire sensory information by emitting signals and/or moving sensory structures. We propose that the energy from locomotion itself could permit control of a sensor, whereby animals use the energy from movement to reconfigure a passive sensor. We investigated high-speed, antenna-mediated tactile navigation in the cockroach(More)
The integration of information from dynamic sensory structures operating on a moving body is a challenge for locomoting animals and engineers seeking to design agile robots. As a tactile sensor is a physical linkage mediating mechanical interactions between body and environment, mechanical tuning of the sensor is critical for effective control. We(More)
In this dissertation, we model biological sensorimotor behaviors of two species, a cockroach following a wall and a human running on a split-belt treadmill, to elucidate the neural processing that underlie locomotor control in biological systems: (1) We model the horizontal musculoskeletal dynamics of antenna-based wall following for the American cockroach,(More)
Insects rely on sensory cues—tactile, hygrometric, thermal, olfactory—gathered with a pair of head-mounted antennae to perform a wide variety of sensory guided tasks. Many questions regarding the potential impact of specific mechanical design features on antennal performance can be directly and thoroughly assessed using an artificial robotic(More)
Animal nervous systems resolve sensory conflict for the control of movement. For example, the glass knifefish, Eigenmannia virescens, relies on visual and electrosensory feedback as it swims to maintain position within a moving refuge. To study how signals from these two parallel sensory streams are used in refuge tracking, we constructed a novel augmented(More)
