Maze

Challenge rules

These rules may not be the final ones, the organizers have the right to modify them as they see fit. If there are any changes we'll let you know at once.

1. The goal of the challenge

It tests the ability of the team to create an autonomous robot which is able to navigate out of the maze in the quickest time possible from the designated starting point to the ending point.

2. Rules for the robot

A. The robot shall be self-contained (no remote controls). The team which implements the robot can choose any material and any form of control mechanism as long as it does not interfere with an external control mechanism.

B. The robot shall not leave any part of its body behind while travelling through the maze.

C. The robot shall not jump over, fly over, climb, scratch, cut, burn, mark, damage, or destroy the walls of the maze.

D. It is recommended for the robot to have modulated or filtered sensors, not to be influenced by ambient light, reflectors or flashes of digital cameras - Organizers do not assume any liability for malfunctioning robots due to environmental light (ambient, flash lamp, IR lamp for recording cameras).

E. There are no limitations for the robot's dimensions or weight, the robot can participate as long as it fits into a cell.

3. Rules for the maze

A. The test is carried out on a square area divided into 10x10 cells of 26x26 cm. Except for the start and the finish cell, which are both black (just the bottom of the cell), all the other cells are white.

B. Between any two adjacent cells there can be a physical wall of 18 mm width and 15 cm height. These walls are arranged in such a way that there exists a path from any cell to any other cell and, between any two cells, the path which passes through a minimum number of cells is unique. Except from the superior face of the walls, which can be of any color, the visible faces of the walls are white. The outside wall encloses the entire maze.

The organisers can not guarantee that the arena is perfectly white, scratches may occur.

C. For all the typical dimensions of the competition area, a variation of at most 5% of the given value is allowed

4. Homologation

A. A.The robot’s maximum dimensions are 26x26 cm.

5. The Competition

A. All the teams that have homologated their robot will have 3 attempts of crossing the maze( one attempt per round), each attempt has maximum 5 minutes.

B. An attempt is considered to be valid if the robot reaches and stops over the finish cell starting from the starting cell (both these cells are selected by the jury and are the same for all teams), without exterior help (the actions of turning the robot on and off are, of course, allowed)

C. The needed times for each valid attempt noted by the jury and are used to rank the teams.

D. When a team member touches the robot and it has not reached the destination, the attempt is considered invalid. The place in which the robot was touched is considered the stopping point. If the robot compromises the integrity of the maze (jams into a wall at high speed, tilting it) the attempt is considered invalid. However, simply touching the walls is allowed.

E. If the robot remains without power during an attempt, the attempt is considered spent and invalid. The team is allowed to change the power supply once only. The times set in valid attempts are important for the ranking of teams.

F. The ranking is made according to the shortest time taken by the team’s robot to complete the main challenge (the shorter the time, the higher the ranking)

G. The ranking places the teams that have not successfully completed the main challenge, ordering them by distance (measured in number of cells) left until the finish cell. If there are multiple teams that have the same distance towards the finish cell, they are ordered by the time taken to reach the cell where they stopped.
