Building Instructions

Attachment for lifting object, especially hex balls if you have them from the Crossover competition.

This robot extends the Tetrix Box Robot chassis for FTC competitions with an additional arm. The arm could be used for lifting and placing objects and could be quite useful. 

There is a special rubber band at the end of the arm, because there are not enough parts in the Tetrix set and we had to use a rubber band. But the principle of the arm is interesting, useful and you should be familiar with it - the arm keeps the motors always in the right orientation.   

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 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 attachment for the Nautiq robot is designed to lift the coral for M01 Coral Nursery from the FIRST LEGO League 2024‑2025 SUBMERGED competition. It performs two actions simultaneously: lifting the mission model loop and opening the door that holds the Reef Segments.

Attachment part of a series of robot attachments for accomplishing the FIRST LEGO League 2013 competition. This specific construction lifts the two vehicles. It uses rubber bands for locking the levers. Take a look at the video tutorials for details explanation on how it works.

Build from LEGO Mindstorms EV3 parts.

When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.

Build with LEGO Mindstorms EV3 parts. 

This construction demonstrates one way of using а rack with a gear wheel. It allows to turn circular motion in to a liniar one.

This robot is designed to easily lift a cup while still holding it upright. With its motor attached to the side of the hub, the robot can lift the cup to any angle you want. You could replace the LEGO cup and make it lift real cups with a few adjustments. Be careful around liquids though, the robot doesn't like beverages like you do!

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 an attachment for the Kriket box robot. It demonstrates how to build attachments that glide over the robot, are pinless and could be quickly and easily replaced and changed with another attachment. This attachment also lifts. Quite cool. Quite cool.
