Light Cooley is an extension of Cooley. We've added two Light/Color sensors to allow for lines to be followed and for the robot to alight to them and we've kept everything Cooley was cool and known about. Build a few attachments for it and take it on a ride for a FIRST LEGO League competition
This is a version of the Gazon robot that has a single color sensor and is useful for cases where you still have not purchased a second color sensor, but need to start working on the FLL competition season missions
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
Here is an idea. What if a robot does not need attachments. What if there is one special attachment on the front that could do most of the work? Probably an attachment that allows you to move a lever in any direction.
This here is a Box Robot with X - Y axys plane. This robot doesn't need active attachments because it has X - Y table that do the job. Imagine that there is a plane on the front of the robot. With the rack mechanism you can move to any coordinates on this plane.
We have a lot of ideas how to make it even better. We will try to release them in the next few versions.
This is Cooley, and, it, is, coooooool. It got all the stuff the cool kids have - two motors at the top, two at the bottom, two wheels on the side and it is slim. Build a few attachments for it and take it on a ride during FIRST LEGO League competition
In the LEGO Mindstorms Robot Inventor set there is only one color sensor. The original Gazon is build from LEGO Education SPIKE Prime where there are two light sensors. The idea behind this robot is to be able to build it from Robot Inventor and to use it during FIRST LEGO League competitions
After the success of the original Gazon robot from LEGO Education SPIKE Prime, we've decided the build a similar robot, but from LEGO Mindstorms Robot Inventor 51515. Teams are participating in the FIRST LEGO League competition with a LEGO Mindstorms Robot Inventor set and we know it will be helpful. But this robot can not be build from a LEGO Mindstorms Robot Inventor 51515 as the set has only one Color sensor. We've build a version of the Gazon robot to address this specific limitation.
The story goes like this. Two engineers meet at a bar (or on discord during the pandemic) discussing which robot to use for this year's FIRST LEGO League 2020 Replay Solution and Review with explanations. They started their cameras, had a hot Carolina Reaper, had an argument, hugged each other, and decided to build Gazon, and use this new robot for the competition. So here it is. Small, 4 motors, 2 color sensors, stable, light.
This is a LEGO Mindstorms EV3 competition robot used in FIRST LEGO League Season 2018-2019 Into Orbit following a Box Robot principle. The robot has passed through the following competitions in Brazil:
Local competition in scho
Regional: Northeast
National: Rio de Janeiro
International: Uruguay
The robot is an modular construction that you could easily build upon. It is not entirely "clean" as it has parts of it not optimezed as in the other box robots, but it is a nice example and a great work from the FLL team.

It's fast. It's on two wheels. It's a motorcycle. And this one is built from LEGO Mindstorms EV3 sets with the use of one additional Medium Motor. If you have two medium motors, great. If you don't have you can build the Handlebar - Chopper Motorcycle built with LEGO Mindstorms EV3, because it uses one large and one medium motor that are available in any EV3 set.
Currently, the motorcycle has no sensors. It's more of an exercise in construction, but if you attach sensors and think of a way to attach them send us a picture.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.
You can also download the program from here.
Zat is fun. Zat is great. It is a simple construction for a car with 4 large wheels. And who does not like cars with large wheels. Built from LEGO SPIKE Core set 45678 + LEGO SPIKE Expansion Set 45680 we had a lot of fun with it on Sunday. It was an idea of my wife and the kids took a lot of time putting things on in and moving it around. Just put things on it and play with it.
This almost box robot is build from the LEGO Mindstorms Robot Inventor set. The idea behind this robot is to be able to build it from Robot Inventor and to use it during FIRST LEGO League competitions
This is the first video tutorial from our course on LEGO MINDSTORMS Robot Inventor programming. In this tutorial we will start with how do we move without sensors. We will demonstrate a simple program. Our hope with this tutorial is that you will see why moving without sensors is a bad approach.
Continuing from the last tutorial, we demonstrate the consistency and reliability of the robot when we don't user sensors. The result is pretty obvious - the robot is NOT consistent and reliable. It just makes a lot of mistakes
In this video tutorial, we demonstrate how to gently push an object to accomplish the mission. "Gently" means that we are pushing but not with force. If we push using force, the mission model will fall, and we will not accomplish the mission. We use LEGO Education SPIKE Prime and the Ultrasonic Sensor.
This is a 10 out of 10 tutorial for pushing gently on a mission model. We also discuss how to build robots that tolerate error and auto-correct their behavior.
What if the robot could make a mistake and still accomplish the mission? That is what we demonstrate with this tutorial - a few principles for error tolerance and self-correction. Even though we start the robot from a few different places, we manage to complete the mission with the same program every time. We use the LEGO Education SPIKE Prime robot, and we continue directly after the 10 out of 10 tutorial
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
