Building Instructions

Dominator is a compact LEGO Mindstorms EV3 Box robot from the family of the Roller Coaster and Kiddo box robots. Similar to the previous two robots, Dominator also can move its front part up, down, left and right. This robot also has the same length of movement as its two predecessors of this type - 8 LEGO pins on the side and up.

The difference is that Dominator has fewer parts and has a perfect center of weight that allows it to use large attachments and lift heavy objects without threatening its stability. The movement on the X and Y axes has the same gear ratio. The light sensors are attached to the movable part of the robot which enables it to both follow a line and recognize the color of various object with height lower than 7 LEGO units.

Meet Kiddo, smaller sister of Roller Coaster. It is smaller, easier to build and easier to control box robot with X-Y moving plate.

The goal of this robot is to have one complex attachment that could move in four directions. With such an attachment you can solve a lot of complex tasks without loosing time changing attachments. It is also quite sturdy and packed

This is an active attachment with gears built from LEGO Education SPIKE Prime robotics set. The goal is to do a precise drop. The attachment could be used for both cargo items.

This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 13th mission of the FLL Cargo Connect competition.

An active attachment with a locking mechanism designed to carry, deliver and drop a large object without letting it go. It accomplishes the FIRST LEGO League 2021-2022 Large Delivery mission

This is a passive attachment used for FIRST LEGO League 2021-2022 Cargo Connect mission called Large Delivery. The attachment has a locking mechanism to lock the large wing to allow us to safely carry it.

This is a passive attachment activated by the robot and not by a motor. It's used for accomplishing the FIRST LEGO League 2021-2022 Cargo Connect Home Delivery mission model.

These are 3D building instructions for an extensible and configurable attachment for FIRST LEGO League 2021 Cargo Connect and the Sorting Center mission. The attachment has 3 axles, and we can place these axles in all kinds of configurations.

Attachment frames are used on Base Robot Chassis to make it easier to add and remove attachments very fast. This frame is for the Box Robot 1. It is a single module build with LEGO Mindstorms EV3 parts and it could handle attachment on all sides. 

This is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.

The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.

Frame for adding attachments on the robot. When using a frame it is very easy to quickly add and remove pinless attachments from the robot. The whole frame could be removed.

The frame contains parts from LEGO Mindstorms EV3.

Active robot attachment for the LEGO Mindstorms EV3 Box robot chassis. The attachment is placed on the top of the robot and uses a system of two gear wheels to transfer the motion to a lever and to .... lift things.

Robot attachment that shows you how a circular motion could be transferred to linear by using a gear and a rack. The final motion is for pushing and pulling things. 

The attachment could be built from LEGO Mindstorms EV3 and NXT parts. 

When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.

Build with LEGO Mindstorms EV3 parts. 

These are 3D building instructions for a LEGO attachment used for the Unload Cargo Ship mission from the FIRST LEGO League 2021-2022 Cargo connect competition. The attachment is used as an extension for the robot to be able to push on the mission model

This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 9th mission of the FLL Cargo Connect competition.

This is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.

This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears

This is the robot that we use to demonstrate a solution for the World Robot Olympiad 2021 Junior competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition.

We started with this robot and it has a few good ideas. It can collect two cars at the same time. We later decided to go for a more powerful robot. Check out WRO 2021 Junior: Slaimi - a post season WRO competition solution robot

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 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.
