Robot Ferda for Robotour 2016 is a modified children's electric car ("ride-on"). The controller (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). The master system is an Android smartphone with special 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.

The robot will use logitech c920 this year.

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.

She was nice and she was beauty,
she was smart and she was fine,
just in one word, she was cutie,
and her name was Clementine.

… all of it with a differentially driven platform, industrial laser scanner, home-made laser scanner, stereo camera, GPS and compass, highly modular message passing software architecture with computer vision and probabilistic localization … simply irresistible.

The base of the robot is modified RC model TRAXXAS E-MAXX (3903) equipped with webcamera, GPS, sonars HC-SR04, IMU with 3D compass and magnetic IRC. This year we will give a second chance to RPLIDAR. The control of the robot and basic sensors is processed via Arduino mega. Image processing and navigation handles Odroid XU4. Robot is programmed in C++ and OpenCV.

The robot chassis is composed of two independent halves connected with axes. This is mainly to handle complex terrain. The wheels are driven by industrial stepper motors and each two are connected via toothed belt. The robot is differentially driven. Motors are controlled over CAN bus. Power provides two gel Pb accumulators from UPS. Robot is controlled by duo of BeagleBone Black boards. They integrated inertial unit, compass, GPS and sonars. There is a special trailer designed for barrel transportation.

The main hardware consists of a Congatec TS180 COM Express module. For the main processing, it communicates with the XBox One Kinect and the Rasberry Pi and displays the crucial information on a Krämer V-800 Touchscreen.

A Raspberry Pi reads the sensor values from the GPS and the Bosch BNO055 and transmits them to the Congatec module. It receives the steering and speed values from the Congatec module, which are transmitted to the Freescale KL25Z microcontroller, which in turn controls the RC-Car model(1:5) via PWM signals.

MECHANICS:

Quadron is a quadricycle (ultimately) autonomous mobile robot. It’s mechanical construction has the car-like kinematic configuration, which means that on the front axle there are two steering wheels, while the rear rigid axle is used to propel the vehicle (2WD). The base of the structure has become an electric quad, produced by Lifestyle-4-U GmbH. The assumption was to create universal platform, which will be used in many independent fields and disciplines. That is why we have introduced a number of electrical and mechanical modifications, especially in the supporting frame. After changes our robot gained the possibility of transporting elements of a fairly large scale, because in border cases up to 60kg, at curb weight of about 60kg. Then we adjusted the drive systems and steering mechanisms, that could be done with electric motors. For the movement of the vehicle corresponds 500W DC motor, while for the movement of the steering wheel is responsible DC gear motor and coupler system. Each engine was equipped with a driver, encoders and security features.

ELECTRONICS:

The robot is equipped with a number of sensors and modules responsible for security, location and orientation in the field. On board are:

The concept of a multi-layer control required the use of computers at different levels. For the lower is responsible board Nucleo STM. While higher layer functions on a PC.

SOFTWARE:

To effectively manage and control the robot, we had to accept the concept of multi-layer software. We decided that the best solution would be to use platform ROS (The Robot Operating System). As a result, we have gained the ability to connect all levels. The lower is responsible for motor control through higher responsible for manual control using a wireless gamepad and simple autonomy, up to the highest layer that collects data from sensors, vision, coordinates designated route and decides where and how the vehicle is moving.

Over the top layer of completely autonomous work is still in progress, but we are at an advanced stage.

E-liška … is already traditional robot of Radioklub Písek. There are always some changes or rather major vehicle rebuilds. This time is Eliška driven by 4x4, with new motor in each wheel. Reworked is also independent suspension of all wheels including problematic steering (hopefully finally perfect).

The main control computer is notebook with Intel processor and static harddisk. Secondary computers for control of various groups are with ARM processor. The energy is stored in gel-lead batteries. Novelty is loading crane on which we are currently intensively working. Unfortunately new space arrangement forces us to do more change then we originally anticipated …

Our rover – called Raptor, consists of about 2000 parts designed by our team. We have used AutoCad Inventor software in the design process. Our Robot consists of a couple of modules, that can work quite independently. The main module is a robot’s body, that houses almost all of the electronics and batteries. The rover is equipped with 6 wheel drive system, mounted on the rocker boogie suspension. Batteries provide energy for 90 minutes continues work and have special compartments with quick changing mechanism. Our on-board computer system is based on SB- RIO programed in Lab View environment. We are able to supervise all useful parameters concerning robot localization and orientation which make the navigation system. The navigation system runs on independent software and hardware platform. Dedicated software is written in C++ within the Robot Operating System ROS. Our system runs on multiple machines with different hardware architectures, file systems and OS but it is not a problem for ROS. Inertial data is provided by high quality Inertial Measurement Unit with six degrees of freedom, containing gyroscope and accelerometer. The sensor’s output is three axis angular velocity and linear acceleration. Using specialized filters system computes very accurate orientation. GPS module outputs position data with one meter accuracy. This data passes through the raspberry pi 3.The weight of Raptors Rover differs depending on the configuration, reaching maximum of 50 kg in the most complex version.

At our robot we use several safety systems. Due to any emergency situation, you could use din style red safety button, with cut off all active parts of rover or send emergency message from base station. Moreover we are able to fully separate batteries from any electric modules of robot, by switching off all switches located at back plate of chasse

The main hardware consists of a Microsoft surface tablet. For the main processing, it communicates with the XBox One Kinect and the Rasberry Pi and displays the crucial information on its main screen. A Raspberry Pi reads the sensor values from the GPS and the Bosch BNO055 and transmits them to the Microsoft Surface. It receives the steering and speed values from the Microsoft Surface, which are transmitted to the Freescale KL25Z microcontroller, which in turn controls the Continuous track model via H-Birdges.
