A program, that makes the Turtle follow a designated course and get back to it, even if it's been manually rotated. It also hides in its shell when it sees anything close to it.
Careful: Gyro Sensor port in this program is port 3. Check your cables when you run this program.
NOTE: The program contains my blocks, that will appear broken if you use version before 1.3.0 of the EV3 Mindstorms Software
This program makes Larvy - LEGO SPIKE Prime larva robot move forward indefinitely! The movement of this robot is very interesting as it works like a caterpillar or larvae! The program works by repeating 3 movements every cycle of the loop:
You may notice that every movement command does two things, or the same thing but a different direction. That is done using a variable that is either 1 or -1, and that gives the direction that the motors should move. This variable is also used to determine which motor should use full power and which shouldn't so that the robot doesn't break itself!
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.
Mantissa, a LEGO Mindstorms Robot, moves and attacks. It uses the ultrasonic sensor and it's two special hands. Follow the building instructions and download the prepared program to directly use the robot.
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!
The third level of the Robotics with LEGO curriculum for students in from 10 to 12 years old.
Learn how the Color sensor works. Your robots can do different behaviours, after checking specific conditions. Robots can become fast speed cars or heavy lifting cranes by the means of gear-trains.

Here is Turtle - a LEGO Mindstorms EV3 robot that is designed to look like a sea turtle (may look clumsy but it's not). It has two sensors - ultrasonic and gyro, capable of following its course and navigating through anything. It can even get "angry", if you annoy it too much.
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.
This robot is part of the category of robots called animals. After following the building instructions you would have a frog that could jump. Of course, the jump depends on the surface and the friction between the robot and the ground... quite complex physics involved. But if you program it to move forward it will try to jump and it is your job to try to make it jump higher.
You could try to extend some of the legs, for example.
These are instructions prepared by LEGO.
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.
This program is for Frog Bot - LEGO Mindstorms Robot that could jump. The program makes the robot move like a toy car with a wind up mechanism. It starts by waiting for three seconds, when you should turn the legs of the frog by hand backward. Then it makes a sound, and the robot starts jumping forward, as much as you have wound it up. The program uses motor rotation sensor to know how much it was wound up.
A program for one of the scariest robots ever - Mantissa.
A collection of MyBlocks, that help you use the Turtle robot. The MyBlocks used are the following:
FollowCourse: Makes the turtle rotate, until it reaches the course it uses. If it's already on it, this MyBlock makes the turtle go forward. It uses the power you set it on.
PickNewCourse: Makes the turtle pick a new course.
HideInShell: Makes the turtle hide in its shell for the designated amount of seconds.
CurrentAndDesiredCourse: Displays the Current course and the course it wants on the display of the robot.
Careful: Gyro Sensor port in this program is port 3. Check your cables when you run this program.
NOTE: The program contains my blocks, that will appear broken if you use any version before 1.3.0 of the EV3 Mindstorms Software
Tohuru, from Maori, means owl.
Tohuru is a SPIKE Prime robot, that holds onto an edge and looks at the nearest object! It uses two medium motors to grip an edge between two wheels. In addition it has a head made out of an ultrasonic sensor, attached to a large motor, which allows it to turn 360 degrees! And most importantly, it looks like an Owl!
