About

Roger D. Santer is a leading figure in the field of neuro-robotics and insect vision, with a particular focus on how the locust nervous system processes visual information to guide rapid escape behaviors. His major contributions lie in reverse-engineering the locust’s "looming detector" neurons—cells that trigger evasive jumps when an object approaches on a collision course. By building robotic models that replicate these biological circuits, Santer has demonstrated how saccadic suppression (the brain’s ability to ignore self-induced motion) and bilateral integration of visual signals can generate robust, reactive direction control. His most cited work, “Retinally-generated saccadic suppression of a locust looming-detector neuron: investigations using a robot locust” (31 citations), provides foundational insights into how insects distinguish real threats from their own movements. His 2009 paper on escape direction control (28 citations) further shows how a simple pair of model neurons can produce adaptive behavior. With over 26 citations for his early sensor work, Santer’s research bridges biology and engineering, offering elegant solutions for autonomous robot navigation and collision avoidance. His work is essential reading for students interested in bio-inspired robotics, sensorimotor integration, and the neural basis of behavior.
