Operation
Put the switch in the "ON"-position. LED1 is lit, the device emits 3 beeps and the KSR4 starts walking. The
emitting diodes LED2, LED3 and LED4 send signals in sequence in order to detect obstacles. When an obstacle
is detected, the received signal is sent to the receiving module, which will then instruct the robot to take
evasive action:
a) When the emitting diode to the right detects an obstacle, you will hear a single beep. The left motor goes
into reverse mode.
b) When the emitting diode to the left detects an obstacle, you will hear a single beep. The right motor goes
into reverse mode.
c) When the emitting diode in the middle detects an obstacle, you will hear two beeps. The two motors go into
reverse mode. Subsequently, the procedure explained in a) is followed.
d) When all three emitting diodes detect obstacles, you will hear three peeps. The device then follows the
procedure described above in c), but turning takes somewhat longer.

Troubleshooting
1. Make sure all components on the PCB are in the right position. Pay particular attention to the polarity of the
IR diode.
2. The sensitivity may be affected by fading battery power and a change in environment. Try to find the ideal
position for the IR receiving module.
3. Apply a little bit of machine oil to the axles of the gears if the KSR4 is not running smoothly.
