This attachment is a demonstration of how easy to detach attachment could be build for LEGO MINDSTORMS Robot Inventor robot where both the robot and the attachment is from the same 51515 set. The principle is useful for accomplishing missions where the mission model should be placed on the FIRST LEGO League field and in the same time should be supported in a way. Check out the tutorial for a demonstration.

With this LEGO robot attachment from LEGO Mindstorms Robot Inventor we accomplish the Rowing Machine from FIRST LEGO League 2020. The attachment works like a hook that catches the wheel of the Rowing Machine mission model and pulls on it. There are gear wheels that transfer the power from the robot motors to the hook at the end. This attachment shows the principle of catching things

This is part one of an FLL 2020 attachment used to accomplish the pull-up bar mission. This is the part of the attachment that stays below the robot. We put the whole robot on this attachment and we move. It is an interesting approach because as we move to the pull up bar this attachment detaches itself from the robot.

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.

This is a robot attachment built only with parts from LEGO Mindstorms Robot Inventor Set. The goal of the attachment is to accomplish the FIRST LEGO League 2020 RePlay mission call Treadmill. The attachment has two gear wheels that could transfer the power from the motors to the wheel. The wheel is the one that is accomplishing the mission as it rotates and rotates. The attachment is pinless.

The second part of the attachment is used to connect the robot with the pull-up bar. This attachment demonstrates a locking mechanism and can hold the weight of the whole robot while the robot is on the pull-up bar.

This is a FIRST LEGO League robot attachment for the Step Counter mission from the 2020 RePlay competition. It is a pinless attachment that is optional and could be used on the robot or we can accomplish the mission without the attachment. It is better to use the attachment as this will give us a more smooth and accurate movement of the robot.

The purpose of this attachment is to flip the tires in the FIRST LEGO League 2020 Replay competition. There are two tires on the field. The attachment must flip them and return them to their initial position. This is an extremely interesting attachment that is using friction and force in order to flip the tires.
