Playstation 2 Controller and Playstation 2 Controller Interpreter
As explained in details above in Section 3.4.1, the Playstation 2 controller will be
communicating with the Interpreter circuit, the latter emulating an actual Playstation 2
console. The interpreter circuit will supply the necessary voltage, the command data and
the clock signal to the controller, whilst the latter will send the data essential for the
control of the robot.
Playstation 2 Interpreter and Transceivers
In addition to communicating with the controller, the Interpreter circuit will also transmit
and receive data from the transceiver. After processing the data from the controller, it will
transmit the data to the robot‟s central unit though Transceivers 1 and 2. Moreover, it will
receive through the Transceivers the vision-related data from the image processing unit of
the robot, and process them and turn on the appropriate LED indicators.
