Koala 2.5 User Manual Rev 1.1 11
3.3.5 Power supply jack
This is the 2.5mm center positive jack used to charge the battery of
the robot. Use only the provided adapter. This will supply the whole
Koala and charge in the meantime the battery (Li-Pol version only).
Input voltage is 15V (max 18V). Current drawn by the robot is 1A and
battery charge is 2A, so the external supply must be able to provide
at least 3.5A.
3.3.6 Reset button
This button resets the whole robot, including the Pico-ITX
motherboard. A simple pulse on this button is enough to restart the
whole system.
3.3.7 Ultrasonic sensors
There are 9 ultrasonic sensors, 1 on both sides, 5 in the front of the
robot and 2 at the back. With these sensors, the robot is able to see
obstacles from approx. 250 to approx. 2500mm. Please notice that it
is not possible to measure distance of nearer obstacles due to the
principle of operation of this kind of sensors.
3.3.8 Contacts for docking station
The Koala 2.5 has some apparent contacts below its body meaning
that you could use a docking station to charge its battery or to
communicate with it. The signals that are provided are: 15V DC input
and I2C connection.
3.3.9 Pico-ITX
The Koala 2.5 is provided with a Pico-ITX computer module with Intel
Atom processor N2800 and 4GB DDR3 SO-DIMM. A SSD hard drive of
40GB (size can change due to evolution of available SSD) is already
installed with an Ubuntu OS.
This computer will be the main intelligence of the robot which means
that the Robot only executes command sent by the Pico-ITX through
a serial port (see Serial communication for more details).
The main connectors of the computer are available on the TOP of the
robot (Pico-ITX front panel):
- VGA Display connector
- Serial port connector (/dev/ttyS0)
- 2x USB 2.0 connector
- LAN interface
- Audio IN (MIC) and OUT (headset)
