Bio-Inspired Polarized Skylight-Based Navigation Sensors: A Review
Animal senses cover a broad range of signal types and signal bandwidths and have inspired various sensors and bioinstrumentation devices for biological and medical applications. Insects, such as desert ants and honeybees, for example, utilize polarized skylight pattern-based information in their navigation activities. They reliably return to their nests and hives from places many kilometers awa...
متن کاملBio-inspired hair-based inertial sensors
In biology, hair-based sensor systems are used regularly for measurement of physical quantities like acceleration, flow, rotational rate and IR-light. In this chapter, two different types of bio-inspired sensors for inertial measurement are discussed, which have been developed using surface micromachining and SU-8 lithography. First, an accelerometer inspired by the cricket’s clavate hair is pr...
متن کاملNovel Bio-inspired Aquatic Flow Sensors
Inspired by the roles of hair cells in nature, this study aims to develop and characterize two new sets of novel flow sensors. One set of sensors developed and studied in this work are flow sensors fabricated using carbon nanomaterials. These sensors are made by embedding carbon nanotubes (CNT) and carbon nanohorns (CNH) into a polymeric substrate and then tested by flowing a conductive aqueous...
متن کاملComment on ‘ A depolarizer as a possible precise sunstone for Viking navigation by polarized skylight ’
A main conclusion of this work by Robars et al. is that a piece of Iceland spar (optical calcite) can be used in a simple manner to find the direction to the Sun using polarized light, even when the Sun is obscured by clouds or just below the horizon, which supports the possible role of the renowned sunstones discussed in Viking Sagas. They propose a method of using an opaque spot on the incomi...
متن کاملSpatial Representation and Navigation in a Bio-inspired Robot
A biologically inspired computational model of rodent representation–based (locale) navigation is presented. The model combines visual input in the form of realistic two dimensional grey-scale images and odometer signals to drive the firing of simulated place and head direction cells via Hebbian synapses. The space representation is built incrementally and on-line without any prior information ...
