These research efforts target the following application drivers: Productivity, Defence, Healthcare and Marine and Offshore, where robotics can provide immense benefits in these unstructured and human environments.
Embodied perception aims to connect sensing with planning and control, so that perceptual understanding of human intentions and environments is situated in the context of effective human-robot interaction and collaboration. The research topics include multiple levels of the perception hierarchy, from low-level sensor design, active sensing, to the extraction of high-level semantic features, such as speaker identification and intention recognition.
Human-robot interfaces address novel interaction modalities that include immersive salient displays for humans. We combine spoken dialog management with other interaction modalities, such as gestures and facial expressions, and create an integrated system capable of deciphering user intentions much more effectively.
Model Learning and Planning
Research in model learning and planning allows a collaborative robot to learn and plan on the fly, as the human intention changes with the progress of a joint task and the general ambient context. We investigate principled probabilistic frameworks that seamless integrate planning and learning.
Planning and Control
Planning and control achieve different levels of autonomy in a hierarchical fashion with human in the loop, with the optimal level of task decomposition between the robotic system and humans. This is obtained from analysis of various data sources at different levels of granularity, to convert these data into meaningful information for effective planning and execution.
Inherently safe robotic manipulators interacting with humans require a radically new design of robotic manipulators with relatively soft structures controlled by intelligent controllers. These controllers take advantage of the inherent dynamics (“intelligent mechanics”) of the robotic structure to achieve safe interaction with humans with improved performance in motion and force control.
Electronics and Communications
Electronics and Communications provide the underlying power and nerve centre of the robotic system, and include signal processing and conversion, communications and embedded computing. The research covers both hardware and software of the cognitive robotic system.
