Reasoning about k inematics is an impor tan t aspect of common sense physics. In earlier work, we have developed the place vocabulary theory of qual i ta t ive kinematics in mechanisms, a fo rma l theory for representing the kinematic behavior of two-dimensional mechanisms. The computa t ion of a place vocabulary is very complex because it takes in to(More)
A theory of qualitative kinematics is required for qualitative reasoning about the motion of objects in space . Such reasoning is important for many physical problem-solving tasks, such as design or robot plan ning. The practicality of earlier work has been limited by the complexity and non-compositionality of computing with configuration space constraints(More)
