Many solutions can be found when it comes to driving the
movements of the robot : the easiest one is to store a sequence of
movements of the engines in the microcontroller.
It is also possible to run the movements through a radio control.
To take the environment into account, obstacles sensors , telemetris detectors …. can be added .
When the robot is supposed to move objects according to an itinerary
made beforehand, it is interesting to make it follow a line on the
ground .
The line tracking module has two optical sencors whose sensititvity is set by potentiometers.
The detectors transmit their information to the
microcontroller which, then adjust or modify the control of the
engines according to whether or not a line is spotted by the
detectors.
Two LEDs make it possible to visualise the conditions of the detectors .
A tiny connector allows the contact toward the main card of the robot .
