Bot Intelligence Group (BIG)
Members | Research | Publications

The main theme of research in Bot Intelligence Group (BIG) is to develop robotic intelligence ranging from the low-level autonomy to the high-level cognitive abilities. We aim to develop robots that can cooperate or collaborate with humans in shared environments, learning to improve themselves over time through continual on- and off-line training, exploration, and interactions with humans and/or environments. Towards this general goal, we strive to answer research questions on how to make robots to understand various semantic contexts of physical and/or social environments, act in both task-effective and socially-compliant manners, and communicate their internal states with other agents in intuitive ways.

Research areas: semantic robot navigation, social robot navigation, human-robot interaction/collaboration, vision language planning, creative AI, arts and robotics, simulation-to-real adaptation, robotic intelligence, cognitive robotics
