The InTech Cup 2025 was successfully held on Saturday, 14 June 2025, at the Ubbo-Emmius-Gymnasium in Leer. Once again, the participants were busy programming, designing and working intensively. Many thanks to everyone who contributed to the success of the event!

The analyses of the disciplines and the overall ranking can be found in the side menu. (Smartphone further down.)

The successful teams in the overall ranking:

Preliminary discussions have already taken place with a school for the coming school year. We will announce the next date and venue as soon as it has been finalised.

See you at the InTech Cup 2026!

Questions about the rules can be sent to intechcup@uol.de. These FAQs will be published here at regular intervals.

You should therefore check here regularly. Changes to the previous version (version 3) are highlighted in bold.

General questions

Question: If a team attaches a pressure sensor for starting, does this sensor count towards the limit on the number of sensors?

Answer: If the sensor is used solely for the start function, then it can be used in addition to the maximum number of sensors.

Question: Do the rotation sensors installed in the NXT, EV3 or Spike motors count when limiting the number of sensors?

Answer: Rotation sensors are excluded from such restrictions for all Lego systems. However, original Lego rotation sensors must be used. If the number of sensors is restricted, this applies to all other types of sensors.

Question: Can more than three motors be installed in the robot?

Answer: Since only one brick is allowed for control and multiplexers (from other companies) are not permitted, the number of motors is limited on the one hand by the number of individual outputs. In the interests of fairness, the external actuators (motors) are limited to four, as this is the number of outputs in the widely used EV3 system.

Question: Does changing the chassis between disciplines still count as a permitted change or is this considered a different basic design?

Answer: Changing the chassis between disciplines is possible as long as the motors are not changed as well. The basic construction includes the brick and the drive motors as well as the brackets for the various attachments and their connecting construction.

Question: Is a second battery pack permitted as a weight?

Answer: The restriction to an RCX, NXT, EV3 or Spike brick also applies to the associated power supply. Either only one battery pack or one set of AA batteries or AA rechargeable batteries are permitted in the brick used. Beyond that, no rechargeable batteries or batteries of any kind may be installed. The use of other original Lego parts remains permitted.

Question: What are all prohibited adhesives?

Answer: All substances that hold two Lego parts together, either by means of an adhesive connection between the parts or by gluing the parts together from the outside using adhesive strips or stickers, are prohibited. This also applies to original Lego stickers. These may only be used if they are not stuck over several parts, but only on the brick, for example.

Question: Are alternative rubber rings allowed (e.g. household rubbers)?

Answer: Even with rubber rings, only original Lego parts are permitted. As rubber rings do not have a Lego label to check, we decide whether it is credible that it is an original Lego rubber ring depending on its appearance and colour.

Questions on the discipline "Sorting out goods"

Question: Are the 5 points for a correctly sorted ball only awarded if the ball falls off the board?

Answer: The ball must have left the competition board (2m x 1m) to be awarded 5 points. If it remains on the plate, then 3 points are awarded for this ball.

Question: Do the holes on the wooden bar have to be exactly 28mm?

Answer: There are always small deviations in the dimensions of available wooden strips, e.g. in the width of 58 to 60mm. The available drill bits can also have different dimensions, e.g. a diameter of 30mm instead of 28mm. The robot should be able to cope with such deviations.

Question: Does the robot have to cross the finish line completely at the end?

Answer: The journey ends when the robot crosses the finish line completely (including the last part/attachment/cable). The time is only then stopped. The points for crossing the finish line are also only awarded after the finish line has been completely crossed.

Questions about the discipline "Collecting goods"

There are no questions yet.

Questions about the discipline "Fight for the last parcel"

Question: Are chains and caterpillar tracks generally not allowed to be used or are they only not allowed to be used for propulsion?

Answer: The ban applies in general, i.e. no chains or caterpillar tracks may be attached to the robot, even for decoration purposes. Lego wheels of all kinds are permitted.

Question: May one robot damage the other and thus render it unroadworthy?

Answer: A robot may not act with the presumed intention of causing damage. Any behaviour by the robot that can be attributed to an intention to cause damage will result in the opposing robot winning the duel. This is decided by the referees.

Question: Can robots be repaired after a duel?

Answer: If parts of the robot become detached, they may be reattached before the next duel, provided it can be assumed that the repair will only take a few moments. Otherwise, we assume that the robots are so sturdily built that no parts can come loose.
