Programs

This program is developed with Robot Inventor - LEGO MINDSTORMS App Python and is used to make the robot align to a line with two color sensor. It's a mechanism we've used with EV3, NXT and now Inventor

This program makes the robot move in a straight line with the use of the LEGO MINDSTORMS Robot Inventor Motion sensor. It's developed with LEGO Education SPIKE App Word Blocks and uses a very simple algorithm for moving straight. When the robot moves slightly to the left or right align it face forward. Try to push the robot slightly. See what happens.

This program is developed with Robot Inventor - LEGO MINDSTORMS App Python and is used to make the robot stop at a distance from the border field.

This program makes the robot move in a straight line with the user of the EGO MINDSTORMS Robot Inventor Motion sensor.

Python program to turn until reaching an angle with LEGO MINDSTORMS Robot Inventor Gyro Sensor.

Scratch program to turn until reaching an angle with LEGO MINDSTORMS Robot Inventor Gyro Sensor.

This program is a solution to the lack of a differential on the robot, which makes its turns slower and bigger! The program reads the realtive angle of the front motor, used for steering, and feeds it to the back motors so as to make one go faster and one slower! This makes the robot turn much faster and smoother. The program requires for someone to turn the steering motor, so experiment with different turning angles and push the limits of the robot! Make sure the markings on the moving and non-moving parts of the front motor align, because that is an essential part of the program!

This program makes Motorka - LEGO SPIKE Prime motorbike robot move in the form of an 8 (or infinity sign:))! It uses the other program for the robot as a base, but instead of letting the steering free, this program controls it so that the robot moves in a shape!

This program is for the target part of Pallo. It consists of a piston with different colored sections, which are detected by a color sensor. The beginning of the piston is a green section, so the program waits for that to change, meaning that the target has been hit, and then it celebrates! The celebration is pretty simple, it measures the color of the new section, which can give us how accurately the target has been hit, and lights the center button with that color! Additionally it writes "YAY" on the screen of the hub. Feel free to improve it however you like!

This program is for Calix - LEGO SPIKE Prime carrying robot. The robot is made to carry an object while following a black line. This is probably one of the first thought that comes to mind when you think of robotics - A robot that can help at home! This robot is made as a first try at this concept. It can move not too heavy objects from one room to the other, following a black line. The program does the following: First it waits for you to put something on the robot and to click the left or right hub buttons. After that it lifts the item a bit and starts following a black line. It follows the line until it sees the same color for more than 3 seconds, thats how the robot knows it has reached the end of the line! After that it rises whatever it is carrying and waits while keeping the object up.

This program makes the Tohuru – LEGO SPIKE Prime Owl Robot move like an owl! But what does an owl move like? Well, we figured a key part of an owl’s behavior is firmly holding onto a branch. So, the first part of the program makes the robot grip tightly onto whatever is between its two wheels. After that, the owl begins spinning its head and searches for the closest object. Once it finds something, it stares at it—menacingly—until it moves away!

This program makes the Big Wheelster – LEGO SPIKE Prime robot move forward until it bumps into something! This robot features one big wheel powered by two Medium Motors. What’s interesting is that the motors must spin in opposite directions to make the wheel rotate. That’s why we’ve created a My Block to control the robot.

The My Block allows you to set how far the robot should move—either a specific number of rotations or indefinitely (by setting it to 0 rotations). It also includes a logic option for direction: use 1 for forward and 0 for backward.

When the robot detects a bump using the front touch sensor, the program makes it reverse using the back wheels, helping it avoid hitting the same obstacle again!

This program makes the Swing Game - LEGO SPIKE Prime robot move the two LEGO figures based on input from their respective controllers.

The color sensor controller uses the colored plate above it to determine movement. If the sensor detects blue, the LEGO figure moves forward. If it detects purple, the figure moves backward. Any other color will make it stop.

The motor controller works similarly. If the motor turns more than 30 degrees forward, the LEGO figure moves forward. If it turns more than 30 degrees backward, the figure moves backward. If it stays within that range, the figure stops.

The goal of the game is for both LEGO figures to reach the center without tipping the swing to either side. Good luck—and have fun!

The programs are designed to be used with Mintonet - a LEGO Volleyball robot.The project consists of several programs:

• Shoot - just shoots the ball.
• ShootWithUltrasonicSensor - this one is pretty much the same, but uses the ultrasonic seonsor infront of the robot as a triger.
• MoveAndShoot - the robot moves sideways until it sees a target and then it shoots the ball at it. This can be either its "volleyball partner" or a box or some other target practice object.
• MoveShootGoBack - the robot moves sideways until it sees a target, shoots the ball and then it returns to its starting position.
• MovePassMove - the robot moves sideways until it sees a target, shoots the ball and then it continues moving. This program is great to be used with second robot and try to pass each other the balls.

These are the programs for our boxing robots and their Joysticks. They are made for a game of two fighters with their respective joysticks, fighting until one is knocked out or its "heart" touch sensor is punched by the other robot. The fighters require the two "leg" motors to be connected on ports B and C and the hand medium motors on port D. The touch sensors should be connected on port 1, however keep in mind that the game may be better without them. The distance sensor has no purpose in the program as it is used only for aesthetics. The joysticks require the motor for forward and backward to be connected on port B and the motor for left and right to be connected on port A. The touch sensor operates the hands and must be connected on port 4.

The block has the following parameters from left to right:

• Maximum angle – the maximum steering angle of the front wheels. It is measured from position of straight wheels, to maximum left or right position.
• Relaxation coefficient – the relaxation coefficient regulates how smoothly the robot follows the line. The default value is 1. In general the range for the coefficient is between 0.5 till 2. If the difference between the value measured by the sensor on black and on white is great i.e. on black is 10 and on white is 80, then the coefficient should be smaller. If those values are closer, then the coefficient should be larger.
• Value on black – the value detected by the light sensor in reflected light mode when it is on the line.
• Value on white – the value detected by the light sensor in reflected light mode when it is outside the line.

In this program, we return the robot to a straight orientation at the end of the program. If there is not enough time for the Mindstorms Gyro sensor the correct the orientation of the robot before the end of the program, then we should do it at the end.
