This is a mechanical cannon that uses the mechanical strain on the plastic LEGO beams to shoot a ball. Because of that the Ball size is very important. It is made to work with standard balls for a ball pool and even better with 41250 52mm LEGO Ball. The mechanism is powered by an EV3 Large motor.
Building instructions for Tower Trunk. The trunk is designed to store cubes and then drop them on a desired spot. It can be used alongside Cube Collector 2 as an attachment for VEX Robot Base 1.

Introducing Kufar! In Bulgarian, Kufar means "suitcase," and just like a suitcase, this robot is easy to "pack" with different attachments for each task.
Unlike traditional box robots, Kufar is an "out-of-box" design, enabling fast, easy attachment swaps. This flexibility allows teams to build a new chassis with customized attachments for each run, making transitions quick but requiring more parts and careful handling due to its gear transmission, which can sometimes cause gear slippage or play.
To improve precision, Kufar’s gear transmission is optimized for lower speeds. Kufar also includes a color sensor to detect specific colored bricks on attachments and a force sensor to start corresponding programs. With two motors for movement and one for attachments, Kufar is compact, efficient, and easy to handle, especially with its sturdy top handle.
We thoroughly enjoyed exploring this innovative concept and hope you find it equally fun and inspiring!
In Finnish, "kuhmu" means "bump."
This robot was designed to resemble a bumper car and to teach a very important lesson about inertia and the center of mass! Its hub is attached pinlessly to the construction, allowing you to move it around and experiment with the robot's center of mass. The robot moves using two wheels attached to two medium motors. It also has a force sensor in front to detect when it bumps into something!
In Spanish, "huracán" means "hurricane."
This robot is designed to resemble a hurricane-type carnival ride. It has two seats for LEGO minifigs, each attached using a flexible hose part. The robot spins them around using a medium motor. This can be controlled using a force sensor, which looks like a clown and stays at a safe distance from the ride!
In Guarani, "tembias" means "stories."
The robot moves using two motors with large wheels. At the front, it has a force sensor to detect obstacles.
This attachment is accomplishing three missions and partly one more mission from the FIRST LEGO League 2022-2023. It is for the Chain Monster robot. It solve mission 6 - HYBRID CAR, mission 14 - TOY FACTORY and mission 15 - RECHARGEABLE BATTERY. It partially solves mission 2 - OIL PLATFORM.
This attachment is a great example for a precise drop attachment. It is designed for the Kriket Box Robot and accomplishes the M14 Toy Factory mission from the FIRST LEGO League 2022-2023 SUPER POWERED competition.

In Dutch, "muur" means "wall."
This robot is designed to have a wall in front of it to clear obstacles, which is where its name comes from. Can you make your own wall?
In Maltese, "Ikkomunika" means "to communicate."
This simple robot is powered by two medium motors. Its controller is tilted for easier screen communication. However, the back two wheels seem to have a problem. Can you figure out what it is?
