RobotCing


Everybody knows Lego. Lego is creating most popular lego sets. They also created Lego NXT a Lego EV3 sets which are easy to program, assemble but after you learning their proprietary language there are not any alternatives. Many users started to use arduino instead of lego but there is a catch - in Quote job to program Arduino you need to have knowledge of electronis as well as knowledge of programming. Despite this fact Arduino is best way how to get started currently because it is cheap and anything can be created with it. Teaching Arduino in school is not many times possible due to requirement of electronics knowledge. I and Veronika wanted to help at teaching robotics so we created robot Cing - multifuncitonal robot for teaching programming and electronics. It is primarily designed for kids older then 11 years old, but can be used by anyone. For easier start we created guides which explain programming to kids and also playfield where kids can try their programs. After mastering programming robot Cing with our libraries you can program robot Cing using Arduino or AVR programming language.

Advantages of robot Cing:

  • Previous knowledge of informatics not required
  • Open-source
  • Designed for every age
  • Easy to get started, and also to build on
  • Easy to learn thanks to playfield and programming guides
  • Great price
  • Robot Cing 1.0

    ALS device


    With Tomáš Pavlík I have created device, which detect activity of muscle and in case of certain muscle movement pattern activates alarm. This alarm is important, because many ALS pacients struggle with calling help when necesary. Our device is better from camera because does not require any source of light so pacient could even sleep with it.

    Robo Rave - hasič


    Robot Rave is worldwide competetion in which people are trying to blow out 4 candles which are randomly placed in playfield. Under those candles four white circles are placed. Playfield is bounded by line so robots know where playfield ends. Playfield contains also wall obstacles.

    Firefighter 1.0

    Firefighter 1.0 was build from Lego Mindstorms. Lego is great for quick prototyping but it has one big problem for this competetetion. It does not have a fan so for blowing out of candles robot used 12cm fan with custom motor and external battery.

    Firefighter 2.0

    My second firefighter was build from arduino and wood. It used faster motors which was great but they did not have an encoder so robot could not turn precise angle or go straight. It used same fan for blowing out candles as first robot.

    Firefighter 3.0

    Third firefighter used multiple arduinos which comunicate with each other using I2C. It allowed him to proces data from more sensors in the same time. For precision move it used stepper motors. Detection of candle was accomplished by computer vision using camera and raspberry pi.

    3D model of Firefighter 4.0

    Firefighter 4.0

    Last firefighter used my project autonomous multidirectional platform. It used Flir LEPTON for candle detection. This camera was placed on turning base so it scan surounding without robot rotating. Robot moves using 4 omniwheel with motors with encoders.

    Line follower


    Line following is common category on robotic competetions. Line following may seem easy but many programs can be quite complicated due to obstackles, color stains and parts of track where the line is missing.

    My first arduino line follower build from lego parts

    I build my first line follower using lego parts for construction as well as motors from lego. Brain of this robot was arduino nano with PID algorithm and 2 line sensors. Robot was quite fast and was able to drive on different surfaces for example sand.

    My second arduino line follower

    My second line following robot was custom build using universal PCB and polulu motors. It used 8 line sensors which allowed him to more precisely detect position of line. It also used PID algorith. Ultrasonic sensor was used for obstacle detection.

    My third arduino line follower with profesional PCB

    My last arduino line follower was created using custom designed PCB which whas manufactured in China. It used Arduino nano as a brain of the robot which handled PID algorithm as well as two Attiny84 which were connected to arduino nano using I2C. Attiny84 were taking measurements from 12 lightsensors and preprocesing them for main microcontroler.

    "Festival vedy a techniky"

    In year 2019 I have competed in competetion called Festival vedy a techniky with my friend Michal Miškolci. We have developed autonomous universal robotic platform which can be used for many project and we configure it as Fire fighting robot. This robot contained 9 proceosors, thermal camera and Raspberry pi. It is able to locate and blow out candle in room.

    Color detection

    In this video you can see robot tracking green object using data from openMV camera. They are computed on external computer and commands are sent back to robot as X coordinate. Main microcontroller than decides which commands to send to our custom motor controlers.



    Azimuth compesnation using gyroscope and accelerometer

    In this video you can see robot compensating for drift in azimuth using data from gyroscope and accelerometer. Main microcontroller reads angle and acceleration in XYZ directions and corrects for drift using PID algorithm. PID algorith adjust speed of every motor to ensure robot is going straight. As you can see robot is much more stable and predictible using this algorith.

    Constant speed and constant force

    Every good universal robotic platform must be able to drive on different types of surfaces. Some surfaces are rough others are slippery. Therefore speed of robot wheels must be dynamically adjusted. This adjustment allows robot to carry heavy objects and have sufficient torque even in slow speeds. We developed algorith to dynamically adjust speed of every motor.

    Thermal vision

    Robot contains thermal camera FLIR Lepton, which enables human detection as well temperature detection. These properties allows robot to work in bad light conditions.

    Vernadský contest


    Science competetetion

    In 2020 I compeated in competetion called "Vernadský contest". I cooperated with Michal Miškolci and we presented usecases of our multidirectional robot which can be used for locating objects, manipulating cargo and many more. We won 2nd place in engineering category. During our presentation we presented abilities of our robot like object and canle tracking using camera, independent movement, modularity and many more. Our multidirectional robot uses 9 procesors openMV camera/thermocamera and Raspberrypi. For movement robot uses omni wheels which allow him to move in any direction without need for any rotation. We challenged problems like flatness compensation of surface and spin as well. We managed to solve them using PID algorithm which takes data from gyroscope and accelerometer. We developed customs sensors and modules for this robot for example motor driver and light sensor. They use I2C for comunication so main microcontroller does not have to read sensors directly and process data. Digital design was done in Fusion360 where we also tested strenght of designed compontent before milling them on CNC or 3D printing them.
