Fire Bird V ATMEGA2560 Hardware Manual
3.5 Powering the robot on battery power
To turn ON the robot on the battery power, make sure that battery is connected to the robot and
move the power switch towards back direction (BP) as shown in the figure 3.7
Warning:
Do not run the robot if battery is low. It will reduce the battery life cycle.
3.6 Powering the robot on auxiliary power
Under normal condition robot is powered by on-board battery. In order to do experiments for
longer duration without worrying about the battery running low, robot can also be powered by
external power source. Auxiliary power source provides regulated 12V, 1Amp supply to the
robot.
Figure 3.15: Robot Powering via Battery and Auxiliary supply
To run the robot on the auxiliary power, use following steps:
1. Disconnect the battery by removing the 5pin relimate connector on the main board which
is located at the bottom of the robot. (refer to figure 3.8)
2. Move the power switch to the BP position (refer to figure 3.3). This is off state for
Auxiliary power mode.
3. Connect AC adapter in the mains. Connect other end of AC adapter in the AUX PWR
relimate male connector on the main board (connector on the right side) and turn on the
AC adapter.
4. Now to turn on the robot, move power switch towards “AP” (figure 3.3).
Warning:
Do not connect auxiliary power while battery is connected to the robot. In such case, robot will
either run on the battery power or on auxiliary power depending on the position of the switch.
Robot can not be turned off in this scenario.
