Research Summary

In the future, robots are expected to work as companions with humans in various areas including domestic scenarios such as care-giving. However, even with well-engineered robots, it would be unrealistic to move robots directly from factories to home environments to perform complex tasks due to safety. Moreover, robots also have to continuously adapt to new environments to avoid hazardous actions since using experts to program a robot for every environment is impossible. Hence, we need adaptive learning algorithms. Spoken language can be considered one of the most effective communication channels to warn robots about threats. A human can guide the robot by a verbal utterance toward a safer interaction. Our goal is to train a robot to safely perform complex tasks with the ability of processing environmental feedback, including guidance and warnings by a human, to shape a proper signal for updating its own policy. Therefore, this research project is focused on three areas: a) given the verbal instructions, generating high-level actions, b) learning low-level actions to fulfill the high-level action, c) learning warnings using the prosodic/sentiment features of the human speaker.
