4.4. AAR hardware
4.4.1. Installing the batteries
The robot has been designed for a power supply lled 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 g. 1, number 4).
ATTENTION!
Installing the connecting jumper JP4 will disable the polarity
check using the rectier diode. Errors in power connections
with installed jumper JP4 might seriously damage the robot.
Connect the battery compartment as shown in the gure (g. 2)
