In this video tutorial we demonstrate a Grab attachment build from LEGO Mindstorms Robot Inventor 51515 set. The goal of the grab attachment is to accomplish the mission of bringing loops back to base without loosing or dropping them when returning. The principle of the grab attachment also demonstrates how to have a a locking mechanism. In this way there is not way to the loop to escape.

In this video tutorial we demonstrate a robot attachment that could be used to lift loops and other objects. Almost every year there is a mission at FIRST LEGO League competitions that involve lifting and the principle is interesting. You can build the attachment, robot and mission model from a single LEGO MINDSTORMS Robot Inventor 51515 set and learn a principle of building an attachment for lifting.

This video tutorial had a different idea than what we recorded. We planned for a push/pull attachment as we've shown such attachments for LEGO Education SPIKE PRIME and LEGO MINDSTORMS EV3. However, the issues with LEGO MINDSTORMS Robot Inventor set 51515 is that we could not figure out an easy way to build a push pull attachment that meets our criteria for an attachment. Because of this we made a slight modification on the idea and it is again push/pull attachment but not moving in a line but in a circle - circular movement.

In this video tutorial we look at an active attachment that uses gear wheel and the attachment is general enough to be suitable for reuse. This means that a lot of different missions could be accomplished with the same attachment. The goal of the attachment is to transfer power to a lever through a system of axles and gear wheels. It is interesting that we change the orientation of the gear wheels.

Throwing/Shooting is a common challenge in FIRST LEGO League competitions and in this robotics video tutorial we are demonstrating an attachment that you can use to throw/shoot a ball. There have been missions for throwing balls like in bawling, or like in soccer/football. The attachment that we use relies on the properties of the plastics used for the LEGO MINDSTORMS Robot Inventor 51515 set - it bends and it throws.

It all started with the famous 2017 mission for flipping a manhole and it was one of our favorite missions ever. Here in this tutorial we demonstrate the same principle of flipping a part from one side to the other. Sounds interesting, yes it is, yes it is.
