Hand Dryer Controls & Sensors
Hand Dryer
Open the ROBO Pro software. Follow the directions below to complete the activity.
In this activity, you will construct your fischertechnik model, Hand Dryer, and run a ROBO Pro control
program to start your model. Refer to the illustration on the following pages as you construct this model.
Start building with the black base unit and add the blocks to it as shown in the illustration. The 1.
number in front of the “x” is the quantity of that item used in this step. The red horseshoe shaped
pieces are for holding the wires in place. The controls and sensors used in the fischertechnik
system have wires with small plugs on the ends to connect to the interface.
In Step 2, assemble the motor and fan blade together with the yellow guard as shown in the
2.
illustration.
In Step 3, assemble the lens tip lamp and the phototransistor to the base unit as shown in the
3.
illustration.
In Step 4, slide the interface onto the four corner mounting blocks and connect the wiring to the
4.
lamp, phototransistor, and motor. (You may have to reverse the order of the red and green
connectors on the motor itself to have it blow forward.) Next to each red and green wire are the
approximate lengths in metric and standard units. Pay attention to the color location of each red and
green connector on the device and on the interface. The red dot on the phototransistor must go
to the red wire or you could damage the device.
Make sure you’ve made all the plug connections on the interface (including power). Place the wires 5.
in the red clips as described before running them in the most direct route to the interface. Feel free
to route the wires in a direction that is more convenient if your wire gets shorter because of repairs.
Just make sure they are making the same connection needed.
