In this study a spiking network controls the iRat in real time. The study demonstrates how the neural controller directs the rat animat’s movement towards temporal stimuli of the appropriate frequency using an approach based on Braitenberg Vehicles. The circuit responds robustly after four cycles when first detecting a light pulsing at 1 Hz, and rapidly after one-to-three cycles when primed by recent experiences with the same frequency. This study [...]

Rat meets iRat

Rats have long since been used in a wide range of behavioral studies. This project is ongoing work to use the iRat as modeling platform for neuroscience studies, for testing neural models of bio-inspired navigation algorithms and for behavioral studies showing rat-robot interactions. Many of the rats observed the iRat, peeping over the wall to check where it was, and often tracking around behind it. Over a period of four days, five [...]

A telerobot, is a telepresence device that allows a user to interact with a robot over the internet. There are few active public telerobots on the internet. This work describes a new Internet telerobot framework suitable for autonomous mobile robots and designed for user edutainment. Users could give the robot navigation goals. The results demonstrated a reliable autonomous mobile robot system that, within 24 hours of continuous operation, reached 447 goals, traveled [...]

aka Maintaining a Cognitive Map in Darkness: The Need to Fuse Boundary Knowledge with Path Integration The iRat was used in one of Allen Cheung's studies to find out if animals need "cognitive maps". From the abstract: "Spatial navigation requires the processing of complex, disparate and often ambiguous sensory data. The neurocomputations underpinning this vital ability remain poorly understood. Controversy remains as to whether multimodal sensory information must be combined into [...]
