In this project we develop a marker-less motion tracking system for hinged insect antennae with a geniculate morphology, as is typical for Hymenopteran insects (honeybees, bumblebees, wasps and ants). The tracking system is being designed to investigate the role of antennal movements in active tactile exploration, pattern recognition and tactile learning.
