Motivated by the five-minute robot, this robot has its own rails!

Uylam is a robot that simulates a stormy environment for its ship. It is made using two piston-like mechanisms powered by a Large motor and offset by 90 degrees to create shaking similar to that of big waves. The ship itself is made out of a medium motor on a turntable and a gyro sensor attached to them. The purpose of this is to explore what is the best position of a ship compared to the waves, so that it sustains the least amount of shaking.

Barco from spanish means boat.

The robot is made to look like a sail ship. The sails are made out of technic panels, attached in various ways to create the best look. Otherwise the robot uses two motors with tyres to move. At the back of the robot there is a Gyro sensor, which helps it maneuver.

Gen comes from Gendema, a bulgarian late 80s rock band, popular with its song about pedalos.

The robot uses two EV3 Large motors to move, but instead of wheels it uses four-legged paddles, attached to the motors. This makes it look like a pedalo. Additionally it slides on the ground much like a real pedalo on the water.

Because of the strange mechanism of movement, the robot has a gyro sensor to help it keep a straight line.

Susan comes from Sue, which is the name of the largest fully preserved specimen of T-Rexes.
Mark comes from Marc Bolan, who is the lead singer/gutarist of the band T-Rex.

The robot is made to resemble a T-Rex (Susan) chasing a car (Mark).

The T-Rex uses a Large motor to go forward and backward. The other Large motor is used for the car, which resembles a very simple 4-wheel vechicle. Susan's task is to spot Mark using the current power option of the motor rotation sensor. As T-Rexes can not notice you if you are moving very slow, Mark is trying his best to move really slow so that he doesn't get spotted!

Antares is the brightest star in the Scorpius constellation.

The robot's main purpose is to show two different grabbing mechanisms - one vertical and one horizontal. The vertical pincers use a medium motor and the horizontal pincers use a large motor. Additionally the robot has a sting mechanism which uses another large motor. For a head it uses an EV3 ultrasonic sensor. With the sensor, the robot can sense when the prey is close enough for a suprise attack.

This is a version of the Midas - a LEGO Mindstorms EV3 Clam robot. The main difference between the two robots is that the motors are flipped. 

The robot uses two Large Mindstorms EV3 Motors to open and close its shell. There are four hoses on the top of the shell which can be reshaped to form different shell styles. It also uses two black bent beams for eyebrows that can be moved to change the expression of the clam. A Castor Ball is used to represent its pearl.

Piscis from Latin means fish.

Piscis is a LEGO fish robot which uses a very interesting mechanism for turning. It's tail uses a medium motor to turn left or right. On its end there are two wheels. When the robot turns its tail, those wheels navigate the movement of the robot and it turns. This results in a cool turning mechanism which resembles how fish move.

Piscis also uses a large motor to move forward and backward. The touch sensor at the front helps it sense danger and return quickly back to the reef.

Watch out for the tooth wheels, they bite!

We love bears. These are great creatures. Do you know that the Polar Bear is the largest bear there is. 

This robot was first constructed years ago for some of the first classes in LEGO Mindstorms Robotics that we held. It is quite challenging, but nevertheless very rewarding when completed and when you manage to program it to walk. Check it out. 

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.

Building instructions for a LEGO Truck. The robot is presented as an Ammo Truck but it can be used for transporting various other objects, too. The construction has a rear drive with each of the rear wheels driven by a Large Lego Motor. The front wheels steer using a Medium Lego Motor. The Brick is placed at the front of the construction which gives the opportunity to easily attach different sensors, based on the task. 

Let's go fast. Large wheels on the back. A lot of torque, small wheels on the front, good aerodynamics. Here we go.

These are building instructions for a LEGO Mindstorms EV3 Drag Car. 

The new Spy is a robot with tank treads, which uses one medium motor to turn three things at once. That is achieved by a gear system. Simultaneously the robot turns its two hands up and down, but in opposite directions and its head - left and right.

The robot moves with the help of two tank treads, attached to two Large EV3 Motors.

Building instructions for a LEGO EV3 Robo-tank. The construction is incredibly simple, with an upright Brick, which makes it perfectly suitable for lessons with students.

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.

Building instructions for a LEGO Mindstorms animal that looks like a Penguin, and walks like a penguin and if you program it, it will even talk like a penguin. Can you program it to talk like a penguin?

"How do you build a forklift using only gear wheels and levers without a rake"... Ok, we would admit that is a difficult question. It even sounds difficult. So let's start with something easy. A LEGO Mindstorms EV3 robot. It lifts objects in the air. It uses two gear wheels that work together and then move in different directions and are placed perpendicular to each other... This sentence kind of got difficult again... Let me try again.

Follow the building instructions with these 70+ steps and you will have a very nice robot and you will learn a simple trick of how to use gears and change the directions in which they rotate. 

"Bot. Spy Bot."

Many of us are fascinated by the idea of spies. Movies for "spies" are also very popular and if you haven't watched them check out the 007 movies. These here are building instructions for a LEGO Mindstorms robot with two touch sensors and one ultrasonic. It could be used as a spy - sneaking closer to you and detecting if you move or if you touch it. The whole idea for this robot came from NXT when there were sound sensors. Currently, there are no sound sensors in the EV3 set, but the robot could again be quite fun to program. 

It moves and it collects. It collects objects.

These are building instructions for a LEGO Mindstorms robot that could collect objects. It is not actually catching them and that's why we call it "Simple Catch Bot". The general case is to program it to move on the floor and collect some of the Mindstorms wheels and tires coming with the 45544, 45560 or 31313 LEGO sets.
