Mobile intelligent autonomous systems (MIAS)

The intelligent manipulator project

The Intelligent Manipulator project concerns the development of a robot assistant consisting of a compliant manipulator and a supporting computer vision system. A manipulator is compliant if the robot must actively maintain its posture and can be overcome without harming the platform. Compliant manipulators are often designed for interaction with humans and are thus exceedingly safe.

The robot assistant is envisioned to be programmed through demonstration. To load a new behaviour into the system’s vocabulary the user must guide the manipulator kinaesthetically through a few demonstrations. Any objects important to the task will be localized by the system using the computer vision system and some user input. Using the object information and these demonstrations a behaviour model is determined statistically. This model should ideally capture the user’s ‘intention’. The system must then be able to reproduce the task with minimal human interference.
