This attachment demonstrates the principle of dropping a part inside a container. It uses parts only from the LEGO MINDSTORMS Robot Inventor 51515 set. The goal of the attachment is to release a lever that is holding the wheel.
This is a complex three parts attachment for the FIRST LEGO League 2020 Replay competition mission called Boccia. The attachment does three things in the same time. It can align to a mission model, It has a contained for boxes that should be dropped and it also has a lever to rotate the boccia target mission model. On top of the that the attachment is working 10 out of 10
The Bench mission in FIRST LEGO League 2020 was one of the more complex missions during the competition. It involved two things - lifting part of the mission model and bringing it back to base and in the same time dropping 4 different boxes which was difficult to achieve. We came up with two solutions for SPIKE Prime and for Robot Inventor and this is the Robot Inventor solution. Take a look. You will learn how to build complex attachments doing more than one thing at a time.
