Optical Parts

Most of these are sensors using infra-red light.  You can use them on your robot, for example, to detect lines on the RoboRugby table, to detect balls or obstacles, or to pick up signals from the navigation beacons at the ends of the table.  There is also a special yellow LED to be used as an indicator on the Handyboard.

NamePictureQuantity LocationComment
Distance sensor distance sensor 2 Z Sharp GP2D12 - measures distance to objects using pulses of infra-red light.  It comes mounted on Lego bricks, with wiring, ready to use.  It will only work in port 4 or port 5 on the Handyboard.

See web page for details.
Manufacturer's data sheet

Beacon receiver beacon receiver 1 Z Infra-red beacon receiver circuit - picks up signals from the navigation beacons on the RoboRugby table.  It will only work in port 8 on the Handyboard.  There is a similar beacon receiver built into the Handyboard.

See beacon web page for details.

Beacon receiver shield shield 1 Z Tubular shield for beacon receiver, to ensure that it only receives light from certain directions.  Cut this to length as required.
Beacon receiver shield shield 1 Z Open shield for beacon receiver, to ensure that it only receives light from certain directions.  Cut out one end and cover the top with black tape.
Reflective optical sensor circuit reflective sensor 2 Z Complete reflective sensor using an OPB704 - emits infra-red light and measures the brightness of the reflected light.  Can be used to detect lines on the table or for other purposes.  It will only work in Handyboard ports 2, 3 or 6, or in higher-numbered analogue ports on the expansion board.

The OPB704 is also available as a component, so you can build your own sensor - see the optical components page for details.

Yellow LED for Handyboard LED 1 Z Yellow LED with built-in resistor, mounted on a Handyboard plug.  To be used as an indicator during the start-up sequence.
