Building instructions for the LEGO Mindstorms EV3 Catapult. The robot has a motor, a clutch to control it for manual shooting and a touch sensor for automatic loading. The bottom base is removed which means the Catapult could not be turned around. Nevertheless, the baseless robot is small enough to be built in class.
Building instructions for the Formula 1 Racing Car, built with LEGO Mindstorms EV3. It can turn with the help of a small motor and is driven by two large ones.
An example program for using this robot could be found at: https://www.fllcasts.com/programs/692hkz-comet-program
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.
Building instructions for a steering car. The front wheels steer through a Medium LEGO EV3 motor while the rear wheels are both driven by a single Large LEGO EV3 motor.
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!
Building instructions for an EV3 LEGO Mindstorms Dump Truck. The back of the truck can be tilted through controlling the medium EV3 motor so that the load can be dumped at a desired location. Also, the robot has a color sensor to determine the type of load it is carrying.
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.
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.
Building instructions for a simple chain tread machine. The robot is actually a simplified version of the Freedom Folk Race tank. All of the ultrasonic sensors are stripped away and the robot can be used for multiple different tasks. The construction is appealing to students and simple enough to be included in a class.
Build from LEGO EV3 Core and Expansion set this robot looks like a scorpion. The Scorpion strikes, when it sees a pray with the ultrasonic sensor and you can use the touch sensor and the rotation sensor to control the spike movement. It has a scissor mechanism at the back using a system of gears and levers.
This here is a base for a robot that has the brick Upside Down. Have you seen Stranger Things? We would admit that this robot does not look exactly like a 'Demogorgon', but this here is the challenge. Can you use this base and make the robot look like a Demogorgon. Add a picture to the comments section below the material.
Do you have other ideas for Demogorgon? Build them with LEGO and add a picture below this material or send it to [email protected]. We would feature it at FLLCasts.com.
Let's build a robot with treads. These building instructions are for a Guard Tank Robot. The good thing about tanks is that they could tackle a lot of obstacles on their way. At least this is what people are saying. Try it. Could you move over LEGO parts with this tank if they are one brick tall, or two bricks tall? What would be the largest obstacle that you could find, over which this tank could still move? Share a video or picture below in the comments section.
We would admit that this tank lacks a gun or an arm, but it is up to you to build one.
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?
Sebastian is a six-legged creature, which technically makes it not-a-crab. Anyway, it still walks sideways and is amazing to build and watch.
You can find the program for Sebastian here.
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.
Don't we all love animals? But it is sometimes difficult to have a puppy at home. Presenting to you - the Puppy robot (drums in the back). It has some of the benefits of a Puppy - it is small, it can follow you with the Ultrasonic Sensor and it can bark (if you program it to). Follow the building instructions. Use it at home or at class.
Again a LEGO animal. This time it looks like an ant. It's interesting that this robot has no wheels and moves in a way very different from the rest of the "wheel robots".
There is much to be learned about mechanics from the way animals move. Ants are a good example. In the real world, an ant could carry a load of 20x its mass. It would be interesting to see how much load could this robot carry? Try it.
The first thing every student wants to build is a LEGO Mindstorms EV3 robot with treads. Well, we have one. Take a look. It's really funny.
Can you make it move? Send us a video or picture in the comment section below.
A fearsome and dangerous robot. It will find a place to hide and patiently wait in ambush.
NB! This robot requres bluetooth connectivity, as its USB port is blocked in the construction.
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.
