An article in Vanderbilt University's Daily Register describes research being done at the Vanderbilt Robotics and Autonomous Systems Lab to develop techniques that will allow a robot to sense and respond to human emotions. The project is divided into two parts: first, developing a sensor system that can accurately detect a person's psychological state and, second, development of a method to process and store the sensory data in real time for use in a robot. At the current stage, the human involved has to wear sensors that monitor their parasympathetic and sympathetic autonomic states. An Arrick Robotics Trilobot is being used as a research platform for the project.
