1.2 Motors
The robot is driven by two motors with 125:1 transmission (respectively 25:1
transmission). The motors are driven by a H-bridge with a 14,7 kHz PWM-
signal. The PWM-signal can be regulated by odometry-sensors, thus it is
possible to drive with constant speed.
1.2.1 Odometry
The direction of rotation and the speed of the wheels is measured by two
photo-transistors and two IR-LEDs on the red gearwheels of the transmission.
The speed is directly proportional to the frequency of the signal.
