Competition task structure and central task module components

The task is to construct a robot system. The competitor should steer and programme the robot to open a door, equipped with a smart door lock of new ages.

In the task the competitor should construct a robot system, which consists of a programmable robot and Arduino UNO, an electronic circuit board and a smart lock of new ages.

The competitor brings with him/her a laptop with Arduino IDE programming environment installed. The competitor do not need to bring with him/her an Arduino UNO microprocessor card. The competition organizer will provide it.

The words of the picture in English:

Robotin rakentaminen ja ohjelmointi = Constructing and programming a robot
Arduino UNO sekä kilpailussa valmistuva elektroniikkakortti = Arduino UNO and the electronic circuit board that will be implemented during the competition
Uuden ajan älylukko = The smart door lock of new ages


Task duration and allotted time

The task consists of these phases:

Module 1. Assembling and testing the smart door lock
Competition time 1 h, 10p

The competitor constructs an smart door lock of new ages from the given materials and tests if it works. The smart door lock will be used in testing and setting up the equipment system, which will be built later.

Module 2. Constructing and setting up the robot
Competition time 4 h, 25 p

The competitor should construct a constructional robot from the given materials. After the robot is made ready, the competitor should calibrate it so that it is ready to use. In the robot, there must be a place for the electronic circuit board, which will be manufactured and placed later during the competition.

Module 3. PCB designing of the electronic circuit board
Competition time 2 h, 10 p

The competitor should design an electronical circuit board on a one side printed circuit board, based on the given circuit plan and other criteria. The designing will be performed with CAD software, which uses Gerber X code (RS-274X). The circuit board is manufactured with an engraving machine during the first competition day and it will be constructed during the second competition day.

Module 4. Constructing the electronic circuit board
Competition time 1,5 h, 15 p

The competitor should construct an electronic circuit board and test if it works, following the instructions.

Module 5. Constructing and setting up the robot system
Competition time 3 h, 20 p

In this phase, the robot system will be setted up. The Arduino UNO and the electronic circuit board are installed to the robot. The competitor ensures an electrical and mechanical connectivity to the robot’s control unit and case. The competitor tests the compatibility and functions of devices and performs basic programming tasks.

Module 6. Programming the robot system
Competition time 3 h, 20 p

In this phase, the competitor starts controlling and programming the robot system so that the robot will be able to open the door, equipped with a smart door lock. Device manuals are available.

The competitor creates a program, by means of which the robot is able to move and open the door, equipped with a smart door lock.

In the end, the competitor will present to the jury, how his/her robot system is working.

Materials, equipment and work phases used and the competition area

For every competitor, the competition organizer provides an own work station. At the work station there will be a lamp with a magnifying glass, electricity sources and a display (VGA, DVI and HDMI). At the competition site, there will also be circuit boards, needed in the constructing tasks, components and other materials, needed during the competition.


What the competitor brings to the competition venue

  • one laptop (with a mouse)
  • a solder, lead-free tin and a solder wick
  • personal hand tools (side cutting tool, needle-nose pliers, screwdrivers, tweezers etc.)
  • digital multimeter
  • oscilloscope
  • test leads and other wires for own device
  • if needed, a magnifying glass / a lamp for surface mount soldering
  • personal protection equipment
  • a pocket calculator (using the mobile phone as a calculator is forbidden!)
  • note-taking supplies

If a competitor does not have a possibility to bring necessary equipment and device with him/her, the competitor must inform the skill coordinator 3 weeks before the competition day. If necessary, the competition organizer can lend some equipment, if it is agreed in advance.

All of programs, needed in performing the tasks, must be in advance installed on the competitor’s own laptop. The competitor is responsible for that his/her laptop will work during the competition. It is forbidden to ask for assistance in computer problems during the competition.

The task can be changed for the competition max. 30%.


A sample task and assessment as a whole

Taitaja Competition enables the develompent of competence and competence demonstration for the competitors. The judges of the skill categories will give feedback to the competitors during the competition and they will also evaluate the competition tasks. The presentations and ideas created during the competition are in the public domain and can be used by an individual or an enterprise. The presentations and ideas can be used as they are or further developed. The Taitaja2019 event is mainly publicly funded from the semifinals to the finals. The materials produced during the event are openly availabe without any usage fees.
