A mechanically steerable vision system that imitates insect head motion can be mounted on insects and small robots. Vision serves as an essential sensory input for insects but consumes substantial energy resources. The cost to support sensitive photoreceptors has led many insects to develop high visual acuity in only small retinal regions and evolve to move their visual systems independent of their bodies through head motion. By understanding the trade-offs made by insect vision systems in…

Insect-inspired AI for autonomous robots
TLDR
It is argued that inspiration from insect intelligence is a promising alternative to classic methods in robotics for the artificial intelligence needed for the autonomy of small, mobile robots and that even for neuromorphic processors, one should not simply apply existing AI algorithms but exploit insights from natural insect intelligence to get maximally efficient AI for robot autonomy.
Mechanisms of punctuated vision in fly flight
TLDR
By studying tethered, flying flies (Drosophila) in a virtual reality flight simulator, it is shown that ballistic head movements (saccades) reset eye position, are stereotyped and leverage elastic recoil of the neck joint, enabling mechanically assisted redirection of gaze.

TLDR
This work demonstrates a new, custom-built, low-weight camera mounted on a 74 mg flapping-wing robot and implemented a convolution neural network (CNN) to classify images, showing that CNNs operating on input from vision, which have previously been deployed only on larger robots, can be used at insect-scale for such tasks.
Controlled Flight of a Biologically Inspired, Insect-Scale Robot

Head movements quadruple the range of speeds encoded by the insect motion vision system in hawkmoths
TLDR
By using its own output to drive compensatory head movements, the motion vision system thereby works as an adaptive sensor, which will be especially beneficial in nocturnal species with inherently slow vision.
