This is the robot that we use to demonstrate a solution for the World Robot Olympiad 2021 Junior competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition.

We started with this robot and it has a few good ideas. It can collect two cars at the same time. We later decided to go for a more powerful robot. Check out WRO 2021 Junior: Slaimi - a post season WRO competition solution robot

This is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.

This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears

This is a pinless attachment for a LEGO Education SPIKE Prime robot that uses the Ultrasonic sensor. The attachment could be placed on top of the robot. As it is pinless, it is easy to quickly place and remove it.

This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 3rd mission of the FLL Cargo Connect competition.

An attachment for accomplishing the Cargo Connect M01 innovation project model mission. It is used to guide the mission model.>

This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 5th mission of the FLL Cargo Connect competition.

These are 3D building instructions for an active pinless attachment from LEGO Education SPIKE Prime set. The attachment is used along with the Gazon robot to push mission models.

This is an attachment for the top of the robot and the attachment is used for lifting different parts. It is reusable as we could change the lever and use the attachment for a number of different missions.

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.

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.

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 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.

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.

LEGO Attachment user for throwing/shooting a ball. It is powered with one motor and uses the fact that the parts of the LEGO set could bend. Build and experiment with it. Many FIRST LEGO League competitions have missions that could be accomplished with attachments that throw/shoot

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.

This flip attachment from LEGO MINDSTORMS Robot Inventor 51515 set is design to flip parts. It can flip a manhole for example, but could also flip other parts. The principle of flipping is quite interesting as it uses two axles and a border.

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.

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.

This attachment demonstrates pushing and pulling with a circular motion. It is useful for FIRST LEGO League competitions where you can grad a mission model and bring it back to base or push/pull on a lever.
