Here is the small Lower Austrian town of Niederkreuzstetten was a building challenge for children. To help attract more, the RTL Lego Master 2021 bring some of his large Lego builds. Children were also encouraged to bring their favorite Lego constructions, both original builds and sets. There was a live Lego construction competition in 2 age groups.
Robotix4Me also had 3 areas with robots to snooper:
- BeeBots,
- Lego Robots,
- First Lego League (FLL) Cargo Challenge.
This time the example build was to stop at the edge of the table using various sensors. Distance sensor is most obvious, but change in light with a light sensor also worked. But construction also mattered: how far ahead of the robot did the sensor need to be to stop in time? How fast or slow could robot go and still stop? Needed more of a challenge: The FLL Lego challenge table was there to try.
