Cover Story: Robot manipulation in a physically constrained environment requires compliant manipulation. We propose a constraint-aware policy that is applicable to various unseen compliant manipulation operations by grouping several manipulations together based on the type of physical constraint involved. The type of constraint determines the characteristic of the imposed force direction; thus, a generalized policy for each type is trained in the environment and reward designed on the basis of this characteristic. This paper focuses on two types of physical constraints: prismatic and revolute joints. Experiments demonstrated that the same policy could successfully execute various compliant manipulation operations, both in the simulation and in reality. We believe this study is the first step toward realizing a generalized household robot. View this paper
