Construction manual for robot kit NIBObee 01.12.2014
1.3 Sensors
The robot is able to learn and to react to environmental conditions by its
sensors. The following subsections describe the sensors in detail.
1.3.1 Touch sensors / feelers
NIBObee has two feelers and four touch sensors to detect obstacles. Each
feeler is controlled by two touch sensors, so it is also possible to detect the
direction of an obstacle:
1.3.2 Floor- and line-following sensors
To measure the reflection factor of the floor under the robot there are three
IR-phototransistors and two IR-LEDs. So it is possible to detect sheers and to
follow a black line. Additionally different floorings can be distinguished, if their
IR-reflection factors are different. To avoid the influences of scattered light it
is advisable to use a modulated signal. This method of measurement is
implemented in the NIBObee library.
1.4 USB interface
The robot can be connected to a computer by the USB interface. It is possible
to upload new software by this interface. Additionally the rechargeable
batteries can be charged by this interface.
