Robots use their hands to 'think': "The PACO-PLUS project sought to test a groundbreaking theory called ‘object-action complexes’ (OACs, pronounced 'oaks'). OACs are units of 'thinking-by-doing'. Essentially, this approach designs software and hardware that allows the robot to think about objects in terms of the actions that can be performed on the object."
