Many invertebrates are ideal model systems on which to base robot design principles due their success in solving seemingly complex tasks across domains while possessing smaller nervous than vertebrates. Three areas particularly relevant for designers: Research flying and crawling has inspired new materials geometries from bodies (their morphologies) can be constructed, enabling a generation of softer, smaller, lighter robots. walking insects informed the controlling motion control) adapting environment without costly computational methods. And research combining wet neuroscience with robotic validation methods revealed structure function core circuits insect brain responsible navigation swarming capabilities mental faculties) displayed by foraging insects. The last decade seen significant progress application extracted invertebrates, as well biomimetic robots better understand how animals function. This Perspectives paper past 10 years Living Machines conference outlines some most exciting recent advances each these fields before outlining lessons gleaned outlook next invertebrate research.

Abstract To navigate towards a food source, animals frequently combine odor cues about source identity with wind direction location. Where and how these two are integrated to support navigation is unclear. Here we describe pathway the Drosophila fan-shaped body that encodes attractive promotes upwind navigation. We show neurons throughout this encode odor, but not direction. Using connectomics, identify local called h∆C receive input from previously described pathway. exhibit odor-gated, direction-tuned activity, sparse activation of in reproducible direction, activity required for persistent orientation during odor. Based on connectome data, develop computational model showing can promote goal such as an source. Our results suggest processed by separate pathways within goal-directed

Anchoring goals to spatial representations enables flexible navigation but is challenging in novel environments when both must be acquired simultaneously. We propose a framework for how Drosophila uses internal of head direction (HD) build goal upon selective thermal reinforcement. show that flies use stochastically generated fixations and directed saccades express heading preferences an operant visual learning paradigm HD neurons are required modify these based on used symmetric setting expose flies' co-evolve the reliability interacting impacts behavior. Finally, we describe rapid new headings may rest behavioral policy whose parameters form genetically encoded circuit architecture. Such evolutionarily structured architectures, which enable rapidly adaptive behavior driven by representations, relevant across species.

Abstract Orienting behaviors provide a continuous stream of information about an organism’s sensory experiences and plans. Thus, to study the links between sensation action, it is useful identify neurons in brain that control orienting behaviors. Here we describe descending Drosophila predict influence orientation (heading) during walking. We show these cells have specialized functions: whereas one cell type predicts sustained low-gain steering, other transient high-gain steering. These latter integrate internally-directed steering signals from head direction system with stimulus-directed multimodal pathways. The inputs are organized produce “see-saw” commands, so increasing output hemisphere accompanied by decreasing hemisphere. Together, our results internal external drives integrated motor commands different timescales, for flexible precise space.

This review article aims to address common research questions in hexapod robotics. How can we build intelligent autonomous robots that exploit their biomechanics, morphology, and computational systems, achieve autonomy, adaptability, energy efficiency comparable small living creatures, such as insects? Are insects good models for building because they are the only animals with six legs? is divided into three main sections these questions, well assist roboticists identifying relevant future directions field of robotics over next decade. After an introduction section (1), will respectively cover following key areas: (2) biomechanics focused on design smart legs; (3) locomotion control; (4) high-level cognition control. These interconnected interdependent areas all crucial improving level performance terms efficiency, terrain operational range. We also discuss how generation bioroboticists be able transfer knowledge from biology vice versa.

Abstract Using odors to find food and mates is one of the most ancient highly conserved behaviors. Arthropods from flies moths crabs use broadly similar strategies navigate toward odor sources—such as integrating flow information with information, comparing concentration across sensors, over time. Because arthropods share many homologous brain structures—antennal lobes for processing olfactory mechanosensors flow, mushroom bodies (or hemi-ellipsoid bodies) associative learning, central complexes navigation, it likely that these closely related behaviors are mediated by neural circuits. However, differences in types they seek, physics dispersal, locomotion water, air, on substrates mean circuits must have adapted generate a wide diversity odor-seeking In this review, we discuss common specializations observed navigation behavior arthropods, review our current knowledge about subserving behavior. We propose comparative study arthropod nervous systems may provide insight into how set basic circuit structures has diversified different environments.
