The InTech Cup is a co-operation project between numerous schools in the region and the Department of Computing Science Education at the University of Oldenburg. The robotics competition takes place at the end of the school year at different school locations. Interested schools are welcome at any time.

InTech Cup 2026

The InTech Cup will take place this school year on 13 June 2026 at Graf-Anton-Günther-Schule (GAG) in Oldenburg. We would like to thank the school for agreeing to organise the InTech Cup there.

The rules document for the InTech Cup 2026 is now available for download. We wish you every success with your preparations.

General questions

Question: If the number of sensors is limited, do the rotation sensors installed in the NXT, EV3 or Spike motors count?

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 the 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 bond 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 glued 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.
