This is a light shield over the color sensor. Covered from the light the color sensor is much more precise.

This is a flip attachment. Arguably the flip missions are some of the most interesting on FLL competitions. The purpose of this attachment is to accomplish the FIRST LEGO League 2020 Cell Phone Mission. It contains two four gear wheels. It is an active attachment. It changes the direction with gear wheels. There is a lot one could learn from such an attachment. It is also build only from parts in the LEGO Mindstorms Robot Inventor Set.

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.

These are instructions on how to build the:

• 3x Gray containers

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.

Are you a football fan? Here are the building instructions you'll need for the construction of the Football Goal, if you decide to play it with a Mindstorms 51515 Robot Inventor set. You'll also need to build the smallest robot Tricky with its Kick the ball attachment. The Mindstorms/Duplo ball is included in the set.

You can find the LEGO set, with which this was built, by following this link.

You can find constructions created to play with Tricky, by following the links below:

1. Bowling Pins
2. Chain Reaction
3. Basketball hoop

The robot is named after the South Pole–Aitken basin, the largest impact crater in the Solar System that has been discovered on the far side of the Moon.

Astronauts, prepare to enter lunar orbit! This robot comes equipped with a stand that can hold a camera or a phone in order to take a picture of the far side of the moon. If your phone or camera does not fit, the stand can be easily modified to suit your needs. With its two motors, Aitken can make both wide and narrow circles around the Moon to ensure the perfect shot!

These are instructions on how to build the:

This is the VEX advanced skills training ground for building your driving skills. Here you have to pick up the construction and put it on the table at the opposite side of the table and then go to finish. It is the single player mode field because it is designed for a single robot to run on the field.

This table is like the first VEX training ground for developing your driving skills, but is for two robots. The idea is to come first to the final without interfering with the opponent robot. 

This was an idea. You would we demonstration a multi-axle power and rotation transmitting box. Well, here it is. Build it. Start it. And see how the power from the motor is transmitted through different axles. The lever will demonstrate it.

These are 3D building instructions on how to connect a diode directly to the batteries and turn it on.
