Based on feedback from many of you in this episode I would like to show you how to build an active attachment that changes the orientation of a gear wheel placed vertically to a gear wheel placed horizontally. This attachment could be used in competitions and shows a basic principle of changing the orientation. All attachments could follow the same principle.
Connect the attachment to the box robot and find the correct number of rotations of the middle motor that would bring the robot up and forward and would attach it to the mission model.
Interesting and useful attachment for dropping a LEGO human at a specific location. It uses a lever and a gear wheel. When the lever is pressed the wheel rotates.
The attachment is constructed from LEGO Mindstorms EV3 sets.
This video tutorial focuses on accomplishing M8 Artificial Habitat of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a simple active pinless attachment mounted at the front of the robot, designed for precise engagement with the mission model.
The goal is to position all four crabs upright with their yellow bases touching the mat for maximum points, a task requiring careful alignment and controlled movements. While it is possible to complete the mission with fewer crabs upright, this run is programmed for the full score, using dedicated movement commands in a separate run for maximum accuracy. This approach combines a reliable mechanical design with precise navigation to meet the mission’s demanding scoring conditions.
