DR243 Dalek Line Tracker Instructions
How it works
The technology behind this line tracker belongs to 2 sensors located on the bottom of Dalek. Each sensor
has a pair of infrared LEDs and an infrared light sensor that controls the corresponding motor.
The infrared LED generates the signal to the paper and the receiver will obtain the reflected signal to differen-
tiate the line from the surrounding area. Once the unit detects the line, it will drive the wheels to run. So, the
reflection of the light is key to drive the wheels!
Drawing a line for the Dalek to follow
A) Line color
It must be BLACK otherwise the reflected infrared signal will not be received by the sensor and the corre-
sponding motor won't drive.
B) Line width
The line width should be narrower than the distance between the 2 sensors. However, we cannot make the
line too thin. Please search and view the pdf “DR243 – Guide Paths” on
http://www.zeonltd.co.uk/filesearch-zeon.php for examples on the width of the lines that need to be drawn.
First use of the Dalek Line Tracker
Running on Straight line
To start, draw a long straight line with BLACK marker on WHITE paper. The line must be 0.8 ~ 1 cm wide.
Turn on the power switch, place the Dalek on the middle of line and it will run along the line immediately.
