We love tanks. You love tanks. Everybody loves tanks. Well, not exactly - more like everybody loves machines with chain treads because they are interesting, not that common, very easy to build and could tackle a lot of obstacles.
This storage box is designed for use in robot missions. Its long shape makes it easy to grab and transport using a wide variety of robot attachments and grabber designs.
This is a simple robot, variation of the Earl bot using treads. You can use the attachment to kick balls sideways. The robot is useful in STEM classes where students have to construct robots quickly.
Building instructions for a steering car. The front wheels are steered by a medium motor, while both rear wheels are driven by a single large motor.
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.
Minto (from the English word Mintonette) takes its name from the earliest version of volleyball.
This robot can move only forward and backward using one medium motor. It can also shoot a ball using another motor and a clever mechanism. It even has a net, allowing it to catch balls from other robots.
Xogo means “game” in Galician.
The robot moves using two medium motors. It has a distance sensor in the front to detect the next robot and a force sensor in the back to detect the robot behind it in the relay. Build two or more robots and you can create a whole relay!
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.
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.
Malen comes from Malentendu, which means misunderstanding in French.
The robot has a color wheel with 4 colors in the back and a color sensor in the front. When you show a color to the color sensor, it can show it back. You can chain multiple of these robots to make a telephone game!
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.
Levi comes from levitama, which means distribute in Estonian.
This robot uses a color sensor to detect the color of a plastic ball. Then, according to the color of the ball, the robot sorts it to the correct side.
Building instructions for a LEGO Mindstorms EV3 robot that we call Space Explorer. The motors are attached in a very interesting way to the brick. Both the brick and the motors are vertical and there are not many robots like this. With its ultrasonic sensor, this robot allows you to follow, find or avoid objects. Just like an explorer. And since it is a robot why not put it in space and call it "Space Explorer".
There is one part that is not from the EV3 sets, but you can actually skip it. You don't need it. Try to find which one.
Grus, from Latin, means Crane.
The Crane uses one motor to turn the hand and one motor to hold the ball. You need to balance the jib first? What can you add to it?
The goal of these building instructions is to build a simple LEGO Mindstorms EV3 robot without wheels. You should then think of yourself how exactly to add the wheel. Which wheels would you use on the front? How are you going to build the third wheel? Here are for example a few recommendations on building the third wheel - 1, 2, 3, 4
Later on you can expland this construction with a grabber as demosntrated here.
This LEGO Mindstorms robot is strange. Can you guess what is strange about it?... The motors are placed in a reverse direction. One of the motors is facing "forward" while the other one is facing "backwards". This means that if you make the robot move forward with a Tank Block in the EV3-G software it will just rotate. To make the robot move forward, you will have to make one of the motors rotate forward and the other one - rotate backwards.
The goal of this robot is to teach students that motors could be placed in many different ways. It is not always the case that the two motors face the same direction. Also, it is quite fun.
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.
