Building instructions for a LEGO robot that shoots 40 mm ping pong balls. The shooting mechanism is powered by two EV3 Large motors, while the whole mechanism is rotated by a medium motor. The robot can store up to 6 ping pong balls and has a Ultrasonic Sensor to detect targets.
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!
It sparks. It's sparkling. Well, the goal of this LEGO Mindstorms building instruction is to spark the imagination when the base of the construction is very simple. Just two motors with the brick above them and one of the most classic ways to attach them together - with angled beams.
The construction could use EV3 or NXT wheels, so chose wisely. As a robot chassis base, it is suitable for all kinds of extensions. An interesting thing is the motors are attached to each other with a frame which is getting very popular in the EV3 world.

The offset beam creates a hook-like motion when rotating the gear, making "hooking" in loops an easy task.
Instructions for a simple Crane construction built from LEGO Mindstorms EV3 set. In order to operate properly, you need to add weight at the back of the jib. The most interesting part of the robot is the design of its hand, so examine it closely.
This construction is ment as a addition to the base line following robot with exposed sensor.
This attachment is accomplishing four missions from the FIRST LEGO League 2023-2024. It is for the Chain Monster Robot. It solve mission 3 - Immersive Experience. It partially solves mission 14 - Audience delivery and mission 15 - Expert delivery by delivering Izzy the Skateboarder to the Skate Park and Emily the Visual Effects Director in Cinema.
Building instructions for the Easy Bot built with LEGO Mindstorms EV3 parts. This LEGO robot is suitable for classes with students in robotics and is one of the first robots that we build. It takes about 10-20 minutes to be constructed by first-time participants.
In this attachment two knob wheels "(32072 ) Technic Gear 4 Knob" engage at 90 degrees angle. One of the knob wheels is a part of the robot and the other is a part of a pinless active attachment. The purpose of this attachment is to demonstrate How NOT to build attachments.
Build the attachment and experiment. See for yourself how it "jumps" up and down when the knob wheels are rotating and you hold the lever by hand.
This attachment accomplishes three missions from the FIRST LEGO League MASTERPIECE. It is for the Chain Monster Robot. It accomplishes Mission 10 - Sound Mixer. It also partially accomplishes Mission 14 - Audience Delivery.
A FIRST LEGO League 2023-2024 attachment for the MiniBox Robot.
This attachment is designed to keep the model from coming undone when dropped from a higher distance. It was done so that the robot could use a higher-position attachment to deliver the model while using lower-placed attachments to solve other missions in the same run.
This is a simple pinless active attachment for the SUV Box Robot.
In this attachment we use "(32498) Technic Gear 36 Tooth Double Bevel". There are four pins added to the wheel and it it this pins that engage with the "(32072 ) Technic Gear 4 Knob". The more important thing is that the knob wheel and the gear wheel are parallel to each other.
While the motor rotates the attachment has 4 points of contact (instead of one or two when two Knob Wheels are in contact) with the robot knob wheel. There are no forces that drive the attachment to jump and lose engagement with the robot.
Following the Spy Bot, we have this new Spy Vehicle. Yes, yes it is using an ultrasonic sensor.
The building instructions are for a robot base that looks like a car but is not exactly a car and has a strange shape. Just like spy vehicles - a car, but not only a car and not just a car.
This robot is made to serve as a cautionary tale for the line following robots with exposed to the ambient light sensors.
Building instructions for a LEGO Mindstorms EV3 Robot Base with 56mm Tires, Version1. The robot base could be used in robotics competitions as FIRST LEGO League, World Robotics Olympiad and others
This attachment is accomplishing three missions from the FIRST LEGO League 2023-2024. It is for the Chain Monster Robot. It solve mission 11 - Light show. It partially solves mission 14 - Audience delivery.
This is an example of a robot for Sumo Robotics competitions. Specifically for RoboteX challenge. As most of the Sumo competitions have specific requirements for the robot size this one follows the 15cm x 15cm requirements.
Sumo competitions could be quite fun and interesting as the goal is to push the other robot outside of the ring.
This attachment is accomplishing three missions from the FIRST LEGO League 2023-2024. It is for the Chain Monster Robot. It solve mission 8 - Rolling camera, mission 12 - Virtual reality artist and mission 13 - Craft creator.
This robot was built by your request. It includes NXT large wheels. The Large LEGOO Mindstorms wheels will give you a faster robot, but be careful, because it will not be that accurate.

This attachment is designed to detach, once it completes its purpose. This is done, so that the team loses less time switching attachments in the base, lowering the chance of human error during the competition.
