Abstract
Structures called triangle tables were used in connection with the SRI robot Shakey for storing sequences of robot actions. Because the rationale for triangle tables still seems relevant, I have recently elaborated the original concept and have begun to consider how the expanded formalism could be used as a general robot-programming language. The present article describes this new view of triangle tables and how they might be used in a language that supports asynchronous ad concurrent action computations.
