Program for the FIRST LEGO League 2019 City Shaper Swing mission. The attachment is attached on the robot and it we just start the program

EV3-G program developer for the FIRST LEGO League 2019 City Shaper Elevator Mission. The robot calibrates the possible of the attachment and then moves forward and backward to complete the mission

These programs are examples of programs that complete the tasks from the third lesson of 3.0 course. The programs are designed for the Vauld Door Robot.

The block that constanlty increase the speed while turning. The goal of this is to reduce the acceleration of the robot when it starts turning so that no modules will fall.
There is only one input parameter in this block and this is the Angle on which you want your robot to rotate.

A robot that can be an ATM or smart lock with color code. The programs pull in and push out the color card and play sounds if the colors are in correct order. When the order is incorrect, you hear an error sound.

The robot takes place in lesson 7 of level 3.0 Security Systems.

This program lets the robot Safe be opened with a password, and demonstrates how passwords can be stolen.

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.

EV3 PLF-block for LEGO front-wheel steered robots. The block has two relaxation coefficients – one for steering to the left and one for steering to the right. The aim is to make the robot follow a line smoothly when the color sensor is positioned closer to one of the wheels.

The block has the following parameters from left to right:

• Maximum angle – the maximum steering angle of the front wheels.
• Relaxation coefficient left – the relaxation coefficient regulates how sharply the robot responds to error, turning left. The default value is 1.
• Relaxation coefficient right – the relaxation coefficient regulates how sharply the robot responds to error, turning right. The default value is 1.
• Value on black – the value detected by the light sensor when it is on the line.
• Value on white – the value detected by the light sensor 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.

This is an EV3-G project that contains two programs implementing an Integral compensation - integral part of the PID algorithm. The first program is for a Five Minute Bot and the second program is for Box Robot. The things that you should be careful when using the program for your robot are the direction of the motors in the steering block; whether the motors in the steering block are written as "B+C" or "C+B" and the coefficients in the two math blocks. The coefficients that we've chosen should work for most of the robots, but will probably not work for some of them. If they don't work, write to us, comment below in the comment section or drop us an email. 

The experiment contains a plot of the Curren Power of Motors B and C and the values of the Gyro Sensor when the robot is moving with a power of 100%. What you could see is that it is not actually moving with a power of 100% because the current power is about 75-80%.

This is the example program using the blocks available at  Blocks Package for Advance Calibration of LEGO Mindstorms EV3 Color/Light sensors. The program makes the robot find the minimum and maximum values and to calibrate the current sensor value depending to the min and max.

This package contains the three blocks used in the advanced calibration section of the FLL course.

The blocks contained are:

• InitiArray block
• CalibrateMinMax
• GetCalibrateValue
