Много отбори имат проблеми с жироскопичния сензора на EV3 и неговите смущения. В това видео показваме един начин за коригиране на поведението и получаването на точно измерване от този сензор.
The first of a series of attachments that we add to a World Robotics Olympiad LEGO Mindstorms Robot. The attachment is an example for collecting ping-balls. The robot and the attachment are in the same construction. The attachment is a base for a container that could be extended.
This is where the confusion really comes. We are keeping the robot orientation straight while the robot moves, but at the end the, robot is not at the fiinal location that we would like it to be. The robot is still about 2-3 centimeters away after moving for about a meter.
Инструкции за дистанционно управление. При него се използва сензор за завъртане, който определя посоката на кормилото, и сензор за допир, който управлява движението. Тук ще откриете инструкции за подходящо шаси.
Дистанционното управление и колата изглеждат заедно така:
This robot has a color sensor and this sensor is used for following lines. Additional Mindstorms EV3 sensors could be place on the robot, like a Gyro sensor or a second Color sensor.
After we take each sample, we perform calculations and these calculations could take different time. It is important to know how much time does it take to perform the calculations. In this video tutorial, we would data log the time and plot the data.
This program makes Swing game - LEGO SPIKE Prime robot move the two people according to the input from the controllers!
The color sensor controller uses the colors on the plate above it to determine how to move the LEGO person. If the color is blue, it moves forward, if its purple, it moves backwards, otherwise - it stops!
The motor controller has a similar program, if it has turned more than 30 degrees forward, the LEGO person moves forward, if it has turned more than 30 degrees backward, the LEGO person moves backward, otherwise - it stops.
The goal of the game is for both LEGO people to reach the center, without the swing tipping to either side! Good luck and have fun!
This program makes Big Wheelster - LEGO SPIKE Prime robot move forward until it bumps into something! This robot has one big wheel controlled by two medium motors, what's interesting is that the motors need to move opposite directions to make the wheel turn! That is why we have made a My Block to controll the robot. It has the option to move for a set rotations or indefinitely(if you put it to 0 rotations). It also has a logic option for the direction that the robot should move, so 1 = forward and 0 = backward.
The program makes the robot turn backwards after it bumps into something, using its back wheels to make sure it doesen't bump there again!
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!
In this video tutorial we demonstrate the behavior of a LEGO Mindstorms Robot Inventor robot when we use the Motion sensor. The Motion sensor was also referred to as Gyro sensor in previous versions of the LEGO Mindstorms Robot. We do not enter into the details of the programming and you can download the programs from the course lesson, but we make a demonstration of how the robot turns to about 95 degrees when we try to turn it to 90 degrees, we explain why and we suggest a way to improve the behavior of the robot.
Is it better to do fast turns or slow turns? Should you save some time by turning fast or should you be more precise by turning slow. Where is the balance? This video tutorial demonstrates exactly this for LEGO Education SPIKE Prime robot, their motion sensor and an ever occurring question on FIRST LEGO League competition which is how to find the balance and where is the balance.
This is one of the last tutorials in the LEGO Education SPIKE Prime programming for Competitions course and it demonstrates what we've all been waiting for - how to reach a mission model from base in a reliable and consistent way when the mission model is on the other end of the field. Naturally what we use are all the different concepts that we've learned in the course and the tutorial is more advanced than the other so if anything is not clear take a look also at the different tutorials an concepts in the course.
With this video tutorial we demonstration the consistency and reliability of the using an intersection to position on the field. We move forward and we stop at the first intersection. We detect the intersection with a sensor. In the whole 10 runs there isn't a single mistake and you can see the precision of the robot on each run. Check it out and experiment with the same program for your robot.
In this program we demonstrate how to program a SPIKE robot to align to а line with the aid of two color sensors. Make sure the line is big enough for the sensor to detect it. For this program to work, the sensors must be placed in front of the wheels.
This program was intended for and tested on the Gazon robot
In this program we demonstrate how to program a SPIKE robot to follow a line with the aid of a color sensor. Make sure the line is big enough for the sensor to detect it and react to it. For some thinner lines, the speed of the robot can be lowered, but if that does not help, the program can be easily adapted to work with reflected light intensity.
This program was intended for and tested on the Gazon robot
In this video tutorial, we demonstrate how to gently push an object to accomplish the mission. "Gently" means that we are pushing but not with force. If we push using force, the mission model will fall, and we will not accomplish the mission. We use LEGO Education SPIKE Prime and the Ultrasonic Sensor.
We use motion sensor to move straight with the LEGO Education SPIKE Prime robot and to control the configurable attachment needed for the sorting mission from FIRST LEGO League 2021-2022 Cargo Connect challenge
In this 10 out of 10 tutorial, we accomplish the Platooning Trucks from FIRST LEGO League (FLL) 2021-2022. The goal of the mission is to connect the trucks to each other and both of them to the bridge. The attachment and the robot pushes the trucks and we do it 10 times to see the consistency and reliability of the robot.
In this video tutorial we accomplish the FIRST LEGO League 2022-2023 SUPER POWERED mission called M04 Solar Farm. We use the chain monster box robot along with a passive attachment that helps us collect 3 of the energy units. The interesting thing about the mission is the collection of the units, of course, but also the way this robot manoeuvres when there is not enough space. It aligns to the lines, it uses the color and motion sensors. Really advance way to align the robot.
