The major difference with this version is electronic. It uses a BETA Version of the soon to be released Mindsensors SensorMUX is a multiplexer which allows the connect of 4x NXT sensors to single NXT port. The Mindsensors SensorMUX can connect any sensor designed for Mindstorms NXT, both LEGO and/or third party sensors.
The Mindsensors SensorMUX is requires an external battery source supplying a voltage range between 6 and 8.4 volts to operate. View my article, "Power the Mindsensors SensorMUX from a 9V Battery" for details on a simple power supply derived from a 9v (PP3 battery) for the Mindsensors SensorMUX.
The whole "Ball Sorting Factory" relies on:
- 3x NXT Programable Bricks
- 6x NXT Motors
- 4x Power Functions Motor
- 3x NXT Touch Switches
