Introduction of teams
two German and two Slovak teams (and 5 Czech)
Welcome new team KaMaRo Engineering (known from Field Robot Event), new machines (ARBot, JECC) and all stayers . When and where you could see the robots? 5th September 2015, Písek city center, Czech Republic. Concurent starts of all robots at 10am, 11am, 2pm and 3pm.

Robot Ferda is based on modified children's electric car ("ride-on") for Robotour 2015.
The controller is based on Arduino with ATmega2560, controls
the motors, utilizes magnetometer as a compass, manages three sonars to detect
obstacles, reads data from an external GPS receiver and communicates with a
Bluetooth converter (to respond to commands from the master system). This
master system is an Android smartphone with proprietary application (RoboNav)
for GPS navigation by the map (derived from OpenStreetMap) supplemented by
visual navigation according to smartphone camera (for keeping on the road).

Robot is controlled via Zedboard with SoC Zynq 7020 manufactured by Xilinx.
It has 512 MB RAM, 32 GB SD, the heart is dual-core ARM Cortex A9 +
NEON at 600 MHz and it contains programmable gate array with 85 thousands units.
Zedboard runs on Linux and as main programming language is used mono and C#.
The chassis is differentially driven with 3rd passive wheel. The modeller
wheels have diameter 17 cm and two motors PG36555126000-50.9K with encoders are
controlled by professional unit SDC2160 by Roboteq and it provides necessary
traction.
There are two optical odometers ADNS 3080 for further position improvements.
The next sense is „touch”. Robot has two tactile FSR sensors integrated in
the front bumper.
Time-tested AHRS VN-100 from VectorNav provides information about robot orientation.
The global position information is handled by GPS uBlox NEO 7M.
Robot has two sonars HC-SR04, which can be rotated via model servo motor.
The control unit for model servos is SSC-32.
Robot has stereoscopy camera with chips Aptina MT9V032, which have global
shutter and are able to work in HDR mode. Camera is movable in two axis via
servos.
The energy source are 4 LiFePo cells with capacity 14.5 Ah and protected by
SBM.
The chassis is built from 2mm thick plywood for air models and spruce beams 7
mm. Simply model domain. All parts were cut by laser.

The robot is based on modified RC car TRAXXAS E-MAXX (3903). It is equipped
with camera, GPS, sonar HC-SR04, IMU with 3D compas and magnetic IRC. Arduino
mega is used for robot control and sensors reading. Odroid C1 running on linux
is used for computer vision and GPS reading. Robot is programed with C++ and
OpenCV.

Our Robot is completely self developed, from mechanics to software. It
has four wheels, two independently steered axis, one main motor and
weighs about 40kg. It was mainly developed as an agricultural robot for
the Field Robot Event. The low level software is written in C++, the
high level software in C# and Java. It has two LIDARs and a camera as
its main sensors.

Robot is based on 4WD chassis of terrain RC model.
The data from GPS and compass are used for grid localization. The candidate
with the highest probability is selected from the grid. Moreover it has to
overweight all neighbors by given ratio to be accepted.
The algorithm for planning path from current winner position to goal is
standard A*.
The road navigation is based on image processing of front camera. The odometry
and GPS position then estimates the distance to crossing, which is realized by
simple wall-following algorithm with compass direction correction.

E-liška has size approximately 95x60x48 cm and weights around 40 kg. The board
voltage 24V is provided by two gel-lead accumulators 12V/18Ah. E-liška has
spring-loaded 4-wheels undercarriage with Ackermann steering and powered all
four wheels, each with its own control unit. We replaced two back motors by
BLDC for this year. We use Lidar Sick , GPS and 9 DOF innertial unit. The main
control provides notebook with operating system Linux-Debian, and motor control
handles own module with STM32. The power steering is addressed by own
construction of H-bridges and 3phase control of BLDC motors. The main program
is written in Python.
