This attachment is accomplishing three missions and partly two more missions from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot

This is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.

The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.

Active robot attachment for the LEGO Mindstorms EV3 Box robot chassis. The attachment is placed on the top of the robot and uses a system of two gear wheels to transfer the motion to a lever and to .... lift things.

This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees. 

It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion

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.

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.

This is a LEGO Education SPIKE Prime robot attachment for accomplishing the FIRST LEGO League 2020 Replay Boccia mission . The attachment is designed for Gazon, LEGO Education SPIKE Prime competition robot.. With this attachment we follow the line with the robot until we reach the team mission and we use the lever on the top to push the blue box. Then we follow the line to reach the Boccia mission, and three things happen: 1. align to the mission model with the front of the attachment, 2. turn the lever to release the green boxes and 3. move the lever to push on the mission model. This is a complex mission requiring a lot of coordination from the robot. Quite interesting I must say.

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 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

This is a passive attachment activated by the robot and not by a motor. It's used for accomplishing the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model.

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 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.
