Koala 2.5 User Manual Rev 1.1 12
3.3.10 Microcontroller
The Koala 2.5 has a dsPIC33FJ64GS608 microcontroller which is
dedicated to the sensors & motors management. This microcontroller
cannot be programmed by the end-user but answers to a list of serial
commands sent by the Pico-ITX (through /dev/ttyS1 COM port). See
chapter “Microcontroller update”.
3.3.11 GPS module
The Koala 2.5 is equipped with a GPS module UC530 from U-blox.
As soon as the robot is turned ON, the GPS module will search for
valid satellites. The robot must be placed outdoor in order to find
enough GPS to get its position.
The dsPIC of the Koala will automatically retrieve main data from the
GPS (position, speed, date, hour, etc…). But the user can also directly
send NEMA command to the module to obtain more specific
information
(see
“ NMEA_manual_for_Fastrax_IT500_Series_GPS_receivers.pdf ”
documentation).
3.3.12 Accelerometer, Gyroscope & Magnetometer sensor
The Koala 2.5 is equipped with a LSM9DS0 iNEMO inertial module
from ST. This module is a system-in-package featuring a 3D
accelerometer, a 3D angular rate sensor and a 3D magnetometer.
Coupled with the onboard GPS, this will provide a complete solution to
make outdoor positioning and path finding.
The max payload of the robot is 3.5kg.
Operating temperature range of the robot is 0 to 55°C.
Battery charging temperature range is 0 to 35°C. Never
attempt to charge it by higher temperature.
