Improving FLL Robot Game. Introduction to task for Lifting
We've already build a number of resources for lifting at FLLCasts.com. But at the end of this course we would have a robot that lifts itself and hangs on the mission model.

We've already build a number of resources for lifting at FLLCasts.com. But at the end of this course we would have a robot that lifts itself and hangs on the mission model.
The next step of lifting a robot to a mission model is to try to use a rack.
The final way for lifting our box robot is by using a scissors mechanism. In this Episode, we would discuss the benefits and advantages of this mechanism.
Let us do a quick recap of the whole lifting mission and its solution
How should an instructor use this course when working with students and a group of students in school
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
There were a few problems with the 40 teeth gears that we were using. Let's list some of them
This video tutorial focuses on accomplishing M06 Raise the Mast and M07 Kraken’s Treasure of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless attachment connected to the bottom of the robot, featuring side guides with stoppers for precise mast lifting and a central rubberized section to catch the treasure chest.
The challenge in this run is to collect the treasure before raising the mast fully, as the mission model locks the chest if the mast is lifted too far too soon. The robot must push and lift with great precision, stopping at exactly the right point to avoid triggering the lock, then continue raising the mast to complete the mission. This sequence demonstrates careful mechanical design, accurate programming, and precise timing to accomplish two interconnected missions in one smooth run.
This video tutorial focuses on accomplishing M01 Coral Nursery and M03 Coral Reef of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a pinless motor-powered attachment specifically designed to raise the coral tree to the coral tree support while delivering reef segments outside the launch area. This attachment was chosen after testing multiple designs, and it proved to be one of the most reliable solutions for this task.
The motor-driven lifting mechanism is mounted using long axle pins due to the gearwheel’s position, and a heavy brick is added on top for extra sturdiness, preventing the attachment from popping off during operation. On the side, a simple holder secures the three reef segments collected in previous runs for easy delivery during this mission. This combination allows the robot to lift the coral tree smoothly, place it accurately, and complete the reef segment delivery in a single, well-coordinated sequence.
How do you lift heavy objects with an attachment? In this episode we show a simple, interesting, but yet not very popular way to lift something heavy with and LEGO Mindstorms EV3 robot and without gears and motors as attachment. As a specific example we are using the Strength Exercise mission from the FIRST LEGO League 2012 competition.
Note for the teacher on how to organize the class to use different robot base constructions to accomplish the mission for lifting.
In this video tutorial we demonstrate a robot attachment that could be used to lift loops and other objects. Almost every year there is a mission at FIRST LEGO League competitions that involve lifting and the principle is interesting. You can build the attachment, robot and mission model from a single LEGO MINDSTORMS Robot Inventor 51515 set and learn a principle of building an attachment for lifting.
Starting with the World Robotics Olympiad 2014 Junior-High challenge we first catch the object on our path. We discuss a good mechanism for catching and lifting balls that can do two movements with one motor.
How to organize the different robots and group of students when working on lifting the robot.
Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.
