4.4. AAR hardware

4.4.1. Installing the batteries

The robot has been designed for a power supply filled with four 1,5V

AAA-cells. If you prefer to use rechargeable batteries the jumper JP4

should be installed as a bridge to prepare the system for a lower

voltage of the rechargeable batteries (see fig. 1, number 4).

ATTENTION!

Installing the connecting jumper JP4 will disable the polarity

check using the rectifier diode. Errors in power connections

with installed jumper JP4 might seriously damage the robot.

Connect the battery compartment as shown in the figure (fig. 2)

connection

Now you may switch on the robot by activating the ON/OFF-switch.

Located directly besides the switch the power LED (LED5) will be

illuminated.
