The bot has to find a lost little mascot bear in a simple maze and transport it as fast as possible back home to a safe place.
- After being started, the Bot has to travel across the playing field, find the bear and bring it back to the starting place.
- Bots are ranked based on the time they spend for the rescue task.
- Before the start, the participants prepare the Bot so that it touches the back wall of the starting area. Since then, no intervention is allowed.
- After the preparation, the referee places the bear somewhere in the target area.
- The participant starts the bot on a referee’s signal.
- The time is measured from this signal to the moment when the Bot returns and both the bot and the bear fully cross the marked line.
- If this time exceeds 5 minutes, the referee will terminate the race.
- The organizers may allow repeating races or rounds; only the best time of all attempts of a bot will be used for ranking in this first part of the contest.
- In the finale part, the races will be held on a knock-out basis.
- In case of a tie, a repeated race may be ordered by the organizers.
- If it results in a tie again, performance of the two bots in qualification may be considered.
- The bot must not be dangerous or excessively annoying.
- The bot is autonomous or remote control.
- Build your own bot or put add-ons on an existing bot.
- The bot must be able to do the task on the playing field, but there is no limitation for any of its dimensions.
- Bots do not have specific dimensions requirements. They can be of any height and width, however participants should pay attention to the width and height of passages on the route. Because of the ground’s
material, the weight of the bot may not exceed 5 kg (although bots with lower weight are expected).
- Just consider that it has to travel from the starting area to the other side of the field and back again and that it must not lean over the walls. So build it so that it can efficiently maneuver.
- How the bot catches and holds the bear does not matter. But it doesn’t damage the bear. It could hold it by a botic hand, shovel, rake, net. You can push it or pull it on the ground. Of course, it may not throw the bear as that would be dangerous (for the bear).
- For the autonomous bot counts that throughout the race (including the start) no external connection is allowed. Since the bot is prepared for start, it must not be touched or interfered with in any way except starting until the referee allows so.
- On its top side, an emergency switch must be located. By pressing it all actuation must be switched off. The switch must be big enough and well distinct so that it can be easily recognized, reached and used.
- The teams will provide at least 2 photographs/images and 2 paragraphs of text describing the bot/team in electronic form for publishing purposes prior to arrival to the competition.
- Bots can perform the task in two ways: autonomously or with a help of remote control.
a) The autonomous bot must perform the task without operator assistance. The bot can use communication with an external computer to perform the program and calculations, however it is prohibited to use operator assistance. The bot moves on the field using sensors.
b) Remote-controlled bots can also take part in this competition – in this case it is allowed to give bot control commands in any way (e.g. using Bluetooth, infrared or radio communication) by one or two operators. Giving orders must be done wirelessly, meaning no physical contact with the bot on the field is allowed.
c) At the final classification of the competition, bots that have completed the task in a fully autonomous manner will be promoted.
- Autonomous methods of going through the maze
Bots can go through the maze in any way. They can use terrain mapping and driving along the programmed route or by staying at a suitable distance from the walls.
- To simplify competition a black 19 mm wide line (made of black insulating tape) can be added to the field that the bots can use. However, the detection of the bear itself may require additional sensors (touch, distance or other), which may be within a radius of 40 cm from the end of the line).
- Playing field ground and the walls) are white.
- The playing field is bordered and contains inner walls forming a “meander”.
- Both the border and the inner walls are approx. 10 cm high and form a simple maze.
- The bot must not pass or “lean” over the walls but it may “look” over them.
- The bot starts from the back side and the bear is lost in the front side of the playing field (the hatching and the blue lines are not drawn on the playing field and serve here only for explanation).
- The playing field may be composed of more pieces with slight level differences. There might be minimal gaps, which, however, should not have any impact on the bots that take part in this competition.
- The starting area (and also the ending area) is located in the bottom left corner of the field and has walls on three sides.
- The upper half of the field does not contain any walls and is the space in which the teddy bear is located
- The bot can scan the area over the surface of the walls, but while performing tasks must travel through the maze.
- It is not allowed to jump over and drive over the walls, or to damage them on purpose.
- The bear is a stuffed teddy bear. It is not smaller than 10 cm and not bigger than 30 cm.
- It is sufficiently contrast in comparison to the ground.
- It is not live and not moving
- The weight is appropriate. 8.
The bear is in the sitting position.
- Although it is suggested to place a gripper (or other element dedicated to moving the bear) at a height of not more than about 12 cm above the ground.
- Two different types of teddy bears can be used in the competition – so that the team can choose a more suitable one before the start.
