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.

This reusable attachment could easily be placed on the side of a LEGO MINDSTORMS Robot Inventor robot and accomplish different missions that require the robot to interact with mission models. It uses gear wheels.

Forth version of a reusable gear attachment. Again, it powers two axles and this time there is a lever connected to one of the axles.

Second version of a reusable gear attachment. This time the black gear wheel is at the top. It is useful when you are constrained by space.

First version of a reusable gear attachment. By following the same principle for assembling the attachments you can change the direction of the gear wheels and build powerful attachments that could accomplish missions in any direction.

Third version of a reusable gear attachment. In this scenario a single motor could power two different axles in two different directions. If you use it to accomplish a mission do not forget to send us a video. We would love to see it.
