This page shows all the robotics tutorials listed without specific grouping. Each tutorial is short, on specific topic, has a video. Tutorials are structured in sequence in Courses.
Sites are outlined on the mat wireframe.
No Equipment Constraint: The mission model cannot earn points if it is touching equipment at the end of the match.
Krill are a whale’s favorite food! Collect the krill and feed them to the hungry whale.
An unknown creature has attached itself to the AUV! Safely release it and deliver it to the cold seep.
The shark was just tagged for research - release it back into its habitat.
Pulleys, gears, and levers are some of the mechanical technologies used to move props to create the special effects for a movie.
Act out the scene by pulling the boat model along.
Every type of artistic venue is filled with experts who are just as critical as the artists themselves. What careers would you find interesting?
Deliver the experts to their target destinations.
There is no show without an audience! We love to share our artistic creations with others.
Deliver the seven audience members to the target destinations.
What makes something art? Create an amazing art piece worthy of being displayed in a museum.
You can use the bricks in Bag 4 to build your team’s LEGO® art piece. Bring it to the match and then deliver it on the pedestal to the museum.
Power can be stored in batteries, but it takes a lot of energy to produce them.
Deliver energy units to the rechargeable battery target area.
Factories use large amounts of energy to make the products we use such as toys.
Deliver energy units to the toy factory bin and release the mini dinosaur toy.
Surplus renewable energy can be used to convert water into hydrogen gas that can be stored in tanks until it is needed.
Deliver energy units to the hydrogen plant target area.
This model should represent the solution to your Innovation Project.
Deliver your Innovation Project model to the hydrogen plant target area.
Water from the river above the dam is stored in the reservoir. Water from lower down the river can also be pumped back up to fill the reservoir at times when there is excess electricity to use.
Place the looped water units from the river above and below the dam into the water reservoir or onto the red hooks.
Electronic devices like toys require energy to work. Rechargeable batteries are a more sustainable choice than disposable batteries.
Insert an energy unit or a rechargeable battery into the dinosaur toy to make it work.
Solar energy can be stored using new concentrating solar power technologies and then used to generate electricity.
Start the distribution of the energy units by moving them off their positions on the mat.
Oil is a non-renewable energy source that can be used to provide fuel for vehicles.
Pump the oil so that the fuel units load into the fuel truck, and then deliver the fuel truck to the fueling station.
The goal of the Innovation project mission is probably to give everybody an easy win on the competition. A mission that does not require an attachment or a complex program and it the same time is quite interesting. In this video tutorial you will see our robot and our innovation project construction, along with how we complete the mission. Hope you like them!
Having a package delivered to your doorstep is awesome! Packages can be transported safely, on time, and to your door.
Load cargo containers safely and efficiently
Connect cargo to all forms of transportation. Make as many connections as you can and transport your cargo by land, sea, or air to its destination!
Shipping efficiency increases by filling the empty container with cargo before transporting it.
Transporting large items can lead to unexpected problems, like maneuvering around a chicken statue along the way. It is important to plan ahead so nothing is damaged and your cargo arrives safely.
The robot moves your Innovation Project onto the RePLAY logo or the gray area around the bench (M04).

Only one counts per stack
If an Upgrade (solar panels, roof garden, insulation) is Independent, and Supported only by a Stack which is at least partly in any Circle:

Bring the blocks to a specific place on the field in a specific way

score one or the other
If there is a team-designed Structure clearly bigger than a Blue Building Unit, built only from your white LEGO bricks
Note: Design and build your own Structure before you compete, then bring that to each Match. You don’t build it during the Match.
Note: Your mission 11 Structure needs to be built from Bag 10 elements only. It can include the red and gray elements. Not all of the Bag 10 elements need to be used.
