Zatty is the smaller sibling if Zat. Zatty is small and cute. It's a car on a frame with 4 small wheels and of course two mini figures riding in it or on it. Built from LEGO SPIKE Core set 45678 + LEGO SPIKE Expansion Set 45680 it was designed by my 7 years old daughter and then slightly improved by me and the colleagues.

In this FIRST LEGO League video tutorial we accomplish the Step Counter mission from the FLL 2020 RePlay mission. The mission model is quite interesting as it can not be pushed fast and it can not be pushed slowly, because it will jam. The robot must push it with the right speed and this proves to be difficult.
In this program we demonstrate the difference between moving the robot without acceleration and with acceleration. After starting the program, you can press the right button to see the robot move without acceleration, or you can press the left button to see the robot move with acceleration and deceleration. The program runs indefinitely, so you can keep testing the robot, without restarting the program. Make sure the robot has stopped moving before you press any button.
This program was intended for and tested on the Gazon robot
This is a FIRST LEGO League mission model alternative to the Cargo Ship's deck from FIRST LEGO League 2021-2022 Cargo connect LEGO Robotics competition. The mission model could be used to practice dropping elements on it and keeping the balance.
In Bulgarian, "kolelo" means "wheel."
This robot moves like a real Ferris wheel. A motor at its base rotates the entire wheel, while the seats are kept upright by gravity, allowing you to add LEGO passengers to them! A force sensor is used to start and stop the wheel's rotation.
This is a Scratch (Word Blocks) program made to accomplish the FIRST LEGO League 2023-2024 MASTERPIECE Competition with the Kufar Out-of-Box Robot. The correct run is detected with the color sensor and is started with the touch sensor.
This video tutorial focuses on accomplishing M01 Coral Nursery, M02 Shark, M03 Coral Reef, and M04 Scuba Diver of the FIRST LEGO League 2024-2025 SUBMERGED Challenge using the Nautiq box robot (a LEGO Education SPIKE Prime robot). The run uses a two-part pinless attachment designed to complete multiple missions in a single sequence. The small angled surface mounted under the robot flips the coral buds from M01 and pushes the shark from M02, while the front arm catches and delivers the Scuba Diver from the coral nursery to the coral reef support.
The back section of the attachment flips the coral reef from M03 using a friction-pin mechanism that stays straight during travel but drops the horizontal arm at the mission model to push the yellow plate and raise the coral reef. Extra axles on the front arm prevent the Scuba Diver from falling during delivery, ensuring reliable scoring. This coordinated multi-mission approach maximizes efficiency by combining pushing, collecting, and delivering into one smooth run.
This attachment for the Nautiq robot is designed to collect the Plankton and Seabed Sample, deliver the Unknown Creature, and accomplish M11 Sonar Discovery in the FIRST LEGO League 2024‑2025 SUBMERGED competition. It enables multiple tasks to be completed efficiently in a single run.
