construction of knowledge and its organization is carried out through a
process of automated reasoning that analyzes the semantic (meaningful)
behavior of the low-level knowledge and their association. The state of
perception itself is autonomous, as the adaptation of its internal parameters
continues for years long until death. It can be best modeled by a semantic net

Fig. 2.12: The different mental states of cognition and their relationship.
Planning: The state of planning engages itself to determine the steps of
action involved in deriving the required goal state from known initial states of
the problem. The main task of this state is to identify the appropriate piece of
knowledge for application at a given instance of solving a problem. It executes
the above task through matching the problem states with its perceptual model,
saved in the semantic memory.
It may be added here that planning and reasoning, although sharing much
common formalism, have a fundamental difference that originates from their
nomenclature. The reasoning may be continued with the concurrent execution
of the actions, while in planning, the schedule of actions are derived and
executed in a later phase. In our model of cognition, we, thus, separated the
action state from the planning state.
Action: This state determines the control commands for actuation of the
motor limbs in order to execute the schedule of the action-plan for a given
