Introduction of teams
this time with YouTube videos
Robotour is returning back to it's origin this year: Prague, park Stromovka. The contest will be probably in unexplored parts of the park, but the base camp will be the same as in years 2006-2008: in Planetárium Praha. And who is coming? If all 12 teams, which sent homologation video, will come, we will see (besides home teams) also representatives from Austria, Slovenia, Slovakia, Switzerland and Russia.
ARBot is a small robotic vehicle constructed for outdoor competitions of autonomous robots. The robot has 4-wheel chassis, where all wheels are driven and equipped with encoders. Robot has camera, GPS, AHRS unit and three sonars. DSP BF537 (on 1000 MIPS) takes care of all computations. Image segmentation, based on learing with a teacher and MSRC database, was significantly speeded up and improved for this year. New non-linear regulation algorithm allows faster speed while keeping precision and quality of control. New is also local map of robot environment and localisation algorithm.
Platform: RC model 1:5 with electromotor. Processing power: Arduino Duemilanove (low-level control) + Gumstix Overo Fire (higher level control) Sensors set: IP camera, Asus Xtion Pro (3D depth sensor), sonars, accelerometers, gyroscopes, magnetic compass, magnetic encoder. Software: Focus on road and obstacle detection, research in global localisation area.
Our robot is based on multifunctional homebuild robot platform. We wanted to make tank-like drive, but used motors were too weak for this, so we added two rotary wheels. On the platform we have portable computer, which takes care of all the computing. The software is written in C#. At the moment we are using Kinect 3D sensor for road recognition, but it’s not working well in sunshine, so we are planning to replace it with IP industrial camera and 2D SICK lidar sensor. Hope we make it working till competition.
Name of our robot is OLAV. The base structure consists of a modified 1:10 RC-car and a mounted aluminium box, serving as a safe haven for main electronic and payload carrier. The electronic system is splitted in two parts. First part is a Controller Area Network (CAN-BUS) which consists of uController controlled nodes, which handle the basic functions (motor, servo, lights, …). Second part is a mini- ITX board (D525MW), which is able to communicate with the CAN-BUS, runs the "brain" of the robot and handles the USB-cam and image processing. The CAN nodes are programmed in C and the mini-ITX runs a Debian distro.
Robot is built on a 1:5 scale RC car. All computations run on onboard notebook, connected with various sensors using an I2C bus. The robot tries to stay on road using a webcamera, which will probably not be integrated with any kind of mapping software, so it will drive itself only using a method called "All ways lead to Rome".
We use 2 arduinos for control and netbook for image processing from camera and Kinect. Robot has ultrasound sonars, GPS, compass and is powered by li-pol battery. Robot is relatively slow but can easily handle terrain or hills.
Our robot is based on four wheel chassis, all wheels driven. The power source are two lead-acid gel accumulators 17Ah/12V. The main sensor for orientation on the road is laser range finder SICK LM100. Nine axis IMU razor AHRS and GPS Navilock is then used for direction correction. The whole control program is written in Python2.6 and runs on Suse linux operating system. We plan new robot, but we are not sure if it will be ready on time.
Modified kids car PegPerego with reworked gas control from MAN truck. We implemented smooth speed control forward and backward, LIDAR for obstacle detection, inertial unit, GPS, ultrasound sensors in front, magnetic compass, camera Sony. The power source is car battery 12V. Processing HW – notebook Hewlett Packard + 100 MBit switch.
Modified model of RC car, smooth speed control forward/backward, LIDAR for obstacle avoidance, inertial unit, GPS, camera, odometer, compass. Processing HW –notebook + 100 MBit switch.
Short Circuits Prague
Robot is based on platform of monster truck model in scale 1:5. The main processing unit is a standard notebook. Hardware status is monitored via Arduino Duemilanove board. Sensors equipment: magnetic quadrature encoder, compass, sonars, Lidar, GPS receiver and camera. Software is written in Python language. The main program receives all current information about HW status by USB. Low level info about HW is processed by micro chip ATMEGA328, which prepares packets for the main program. The main program transforms this low level info into HW independet structure. It also takes care of PID speed control, localisation from odometry, GPS and compass, obstacle detection and avoidance and finally navigation on given track. The robot recognizes the road in front of the vehicle from camera and lidar data. Obstacles are then detected via sonar and lidar. Information from these sensors is represented in local map, where Vector Field Histogram methods searches for new path.
4-wheel autonomous robot, equiped with 7 infrared distance sensors, GPS, web-cam, microcontroller and PC.
