This page lists some of the rules-related questions we repeatedly receive. Of course it cannot be exhaustive, so if you do not find an answer here, contact us. It means exactly that it must not be dangerous or excessively annoying. That applies to all its living or nonliving environment like the playing field, the bear, other contest nxt 3 chassis robot, referees, public etc.
What is and what is not dangerous or excessively annoying is, among others, defined by laws, generally accepted regulations and referee decisions. For example, a robot equipped with a chainsaw would be both dangerous sharp saw and annoying the noise. We also recommend using common sense.
Where appropriate, the robot also must avoid collisions with the opponent. The robots should not hit each other and in the case of nxt 3 chassis robot touch, one robot must not move the other.
Bumping and ramming would be considered dangerous; this of course does not apply for Mini Sumo neither for RoboCarts where the contact with the opponent is part of the nxt 3 chassis robot. May we use lasers?
If they are not dangerous, the robot may use any kind of sensors, be it contact bumpers, switches etc. If you are not sure about the safety, contact the organisers well in advance. May the robot touch the walls or bump into them? Yes, nxt 3 chassis robot is must not damage or destroy them. May I start the robot using remote control? Remote control is external connection which is not allowed during the start.
May I stop the robot using remote control? It is external connection which is forbidden! When using remote controls for debugging, you will have to detach it its receiver from the robot for the match.
In case of built-in e. If my robot is smaller than 10x7 cm, the marking would not fit on it. Is it a problem? In such case, we could make an alternative marking. Can you give us exact mm dimensions of the playing field, the walls, the bear etc.?
Which exact colours will be used RALwhich materials? We do not specify such unimportant details. Build your robot so that this does not matter.
Will the playing field be smooth? Will it be constructed from one or more pieces? The playing field may be constructed of more than one piece. We will aim for a flat playing field without considerable steps or gaps etc. May we us a combustion motor? Do not use nxt 3 chassis robot engines, pyrotechnics, caustics etc. As the contest will be held indoors, we would consider it dangerous and annoying.
May we use Li-Po accumulators? But that applies to any kind of energy source. May I use a computer for controlling the robot, image processing etc.? As for autonomous robots, all systems — including that computer — must be in the robot so if the computer is inside, then yes, you can use a computer. If the control is off the robot and there is some communication between them then it is nxt 3 chassis robot an autonomous robot.
If you use some kind of wireless connection e. I'd like to know if the 'electronic fight' systems, e. Intentional interference, noise production, sensor jamming etc. That is a brute force solution, not a clever technique. Moreover, it could harmfully affect not only the opponent but also robots in other contests, measurement instruments, wireless connection of referee computers, camera focusing, security instruments, communication and security devices etc.
In such case, you would be disqualified without hesitation, that is clear. So, this is not allowed. The teams should aim for clever construction, algorithms, procedures for their robot defence. Our competitions are primarily for amateur, students, fans; it is more important to learn than to find our which robot is the best one, especially if that should be because its builder can access or can afford buying super-hi-tech technology.
So passive defence is allowed if taken on reasonable level and with common sense. May our robot depoloy in several pieces? If you ask about the possibility to use two robots in one match, then the answer is "definitely no" for all competitions except Free Style.
During the match, single robot competes against single opponent. It might happen that your nxt 3 chassis robot fells apart, but that is a clear mistake which should not happen and definitely nxt 3 chassis robot as part of the strategy. In Free Style, this is possible - your "exhibit" may show nearly anything, including multiple robots cooperating.
Is it compulsory to bring a poster about the robot? Our robot is not so complicated, and many parts are completely visible, so we could explain it as people ask to us. For Free Style and Roadside Assistence, it is compulsory, you must nxt 3 chassis robot it and also nxt 3 chassis robot it to your registration.
It is written so in the rules: People do not ask. What is trivial for you might be new for others. The Roadside Assistence should also serve to other participants as a tool to motivate them for further progress so having your robot well nxt 3 chassis robot on the poster helps a lot.
The posters will be displayed in the main hall for all people, but general visitors will probably not have access inside the teams' zone so that would disclose them from the knowledge should they have to only ask. To make it easier, the poster may be split to more pieces, e. Construction Kits FAQ 1. What does it mean the robot must be constructed from one selected construction kit?
What if it does not contain a sensor I need? The robot must be constructed fully from the selected kit, i. If the kit does not feature some of the mentioned areas, the participants may use anything else.
For example, the control unit is present in Lego but not in Meccano while the propulsion is present in both, therefore a robot built from Lego must have the Lego control unit RCX, NXT, EV3 as well as Lego motors, while a robot built from Meccano must have Meccano motors but can have any control unit be it Arduino, Raspberry Pi, your own or any other. You also have to equip your Lego robot with official Lego sensors and cannot use your own.
See also this list. Can I use non-original, but commercial sensors for Lego? Lego produces sensors, and the rules say you have to use sensors from that kit of your choice. Therefore you have to use Lego sensors and cannot use other sensors. Parts used for Lego-based robots must be manufactured and distributed by Lego or Lego licensed parts from third party manufacturers.
Lego does not produce accellerometers. Can I use my own? If there is something the producer makes in a specific category structure, control, sensorics, actuationyou have nxt 3 chassis robot stick to the range the producer offers.
However, sensors and control unit can be whatever you like because Meccano does not produce sensors nor control units. But Lego makes some sensors and therefore you have to use those. You mention "single-purpose specialized robot kits" are excluded.
What exactly nxt 3 chassis robot that? A "single-purpose specialized robot kit" is something which is not a general construction kit. You build a single robot but you cannot build more than that. If I use Lego, can I use more control units for one robot?
Yes, if all of them are Lego and all are mounted at the robot. If you need, you can even combine them, e. The same with the sensors - use as many sensors as you need, provided that all are from Nxt 3 chassis robot. Yes, if they are nxt 3 chassis robot the same brand name e.
May I use strings, wires, rubber bands, stickers? If they come from your construction set box "as bought" then yes, you may. However, if they were not originally part of the construction kit, then they cannot be used for the construction of your robot. Such additional parts may be used only for decoration and must not be used as support material, to reinforce the chassis etc. So you may equip your robot for example with a flag but that flag must not be used otherwise.
I need to have some buttons on my robot, can I add them? There is one exception - the emergency switch may be of any origin. Of course, if the manufacturer does not provide any sensors, you may use whatever sensor you like, including the buttons.
Does the remote control in Bear Rescue Beginner Kit contest need to be made also of the construction kit parts?
