Micro-Rato and Ciber-Rato


The Competition Micro-Mouse is a robotics competition that is held regularly since 1995, organized by the Department of Electronics, Telecommunications and Informatics of the University of Aveiro. Since the 2001 edition it is possible to participate in two distinct modalities:

  • The “Micro-Rato” modality
  • The “Ciber-Rato” modality

What is the “Micro-Rato” modality?

The "Micro-Rato" modality is a competition between small autonomous mobile robots, with dimensions not exceeding 300x300x400mm. During the competition that evolves in an unknown maze, these robots must complete two objectives in sequence: the first objective is to go from the “departure area” to the “beacon area” and the second objective is to return to the “departure area", or as close as possible to that area, using, for this, the information collected during completion of the first objective. In any case the robots must avoid any obstacles that they encounter, including other robots.

The "beacon area” is a 1m diameter circle painted in black (non infrared reflective), where, in its center, stands a 28cm height infrared beacon. The "departure area" has no indication or marking that can serve as a reference to the robots in the competition.

What is the “Ciber-Rato” modality?

In the "Ciber-Rato” modality the competition evolves in a simulated environment. All virtual robots have the same type of sensors and actuators. A simulator sends to each robot measured values of the sensors, it receives from the robots velocity commands to each “motor” and update accordingly the positions of robots in the maze. The participating teams build the program that allows their robotic agents, through sensory data sent by the simulator, to command the "motors" in order to meet the objectives of the competition.

Additional information can be obtained through the rules of both modalities (in English) and on the website of the competition (in Portuguese) http://microrato.ua.pt



  • From 22/01/2008 to 22/02/2008 - Team registration


Team registration is accomplished by filling a registration form (to be made available here on 22nd January). Registration forms should be sent by mail to the Organization Comittee, up to the registration deadline (22/02/2008). Note that a registration form will only be considered eligible if sent together with the registration fee or with the proof of payment for a valid bank transfer.

Forms of payment:

Payments regarding FNR 2008 registrations – either robotic competitions or scientific meeting - can be performed through one of the following methods:

  • International bank check, in euros, endorsed to "Universidade of Aveiro - Festival Nacional de Robótica", and sent along with the registration documents.

  • International bank transfer to the Robotics Portuguese Open, according to the following references:

    Company: Universidade de Aveiro
    Address:   Campo de Santiago
    3810-193 Aveiro
    Account Name: Festival Nacional de Robótica
    Bank: Caixa Geral de Depósitos - Aveiro
    IBAN: PT50 0035 0836 0000 1699 6301 4

PLEASE NOTE: If you use international bank transfer, a copy of the transfer proof issued by your bank should be sent along to the Organization address with the registration documents. Only upon the reception of this evidence will the Organization be able to issue a receipt. The Organization will not assume any bank transfer expenses.
