This attachment is accomplishing three missions and partly two more missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot
When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.
Build with LEGO Mindstorms EV3 parts.
For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
This is a heavy lifting attachment and it can lift mission models vertically. It is build entirely from LEGO MINDSTORMS Robot Inventor 51515 parts. This is one of the more complex and interesting attachments that we demonstrate in the course and it show how a few gear wheels and levers could be used to change the motion from circular to linear. This is powerful concept that could be very valuable during FIRST LEGO League competitions.
We use this attachment to demonstrate the principle of an active attachment. This is an attachment activated from the motor. It has one level attached to it. It could be reused. The attachment transfers power from the motor to the end of the lever and we can accomplish missions like the Power Switch mission from the FLLCasts Off-season mission models.
