How honeybees make grazing landings on flat surfaces by Srinivasan, M V, Zhang, S W, Chahl, J S, Barth, E, Venkatesh, S

“…Freely flying bees were filmed as they landed on a flat, horizontal surface, to investigate the underlying visuomotor control strategies. The results reveal…”

Insect-inspired estimation of egomotion by Franz, Matthias O, Chahl, Javaan S, Krapp, Holger G

“…Tangential neurons in the fly brain are sensitive to the typical optic flow patterns generated during egomotion. In this study, we examine whether a simplified…”
