How to follow a line using Lego MINDSTORMS
Прост робот за следване на линия. Сеон може да бъде програмиран да следва линия, но конструкцията му не позволява просто патешко следване на линия, а изисква използването на по-усъвършенстван метод.
Това е възможно най-обикновеният робот, който следва линии. При него има само един сензор в предната част между двете задвижващи колела и използва греди за шарнири вместо трето колело. Опитайте да го направите. Следвайте инструкциите и след няколко минути вече ще можете да следвате линии.
This is a LEGO Education SPIKE Prime robot attachment for accomplishing the FIRST LEGO League 2020 Replay Boccia mission . The attachment is designed for Gazon, LEGO Education SPIKE Prime competition robot.. With this attachment we follow the line with the robot until we reach the team mission and we use the lever on the top to push the blue box. Then we follow the line to reach the Boccia mission, and three things happen: 1. align to the mission model with the front of the attachment, 2. turn the lever to release the green boxes and 3. move the lever to push on the mission model. This is a complex mission requiring a lot of coordination from the robot. Quite interesting I must say.
Calix comes from Latin, meaning cup.
Calix is a robot designed to carry small objects—like a cup—while autonomously following a black line. When most people think about robotics, they imagine machines helping with household chores. Calix is a simple example of that vision brought to life. You can place a cup on it in the kitchen, and it will deliver the cup to the end of the black line!
The robot is powered by two SPIKE Prime medium motors for movement, and it uses a color sensor to follow the line precisely. At the front, a large motor connected to a gear system lifts and lowers the cup, allowing for easy pickup and delivery.
Calix is an elegant demonstration of how even simple robots can be designed to perform useful tasks—making robotics more approachable and practical for everyday life.
Името на робота идва от най-скъпата яхта в света, "History Supreme"("Хистори Сюприйм"), купена за около 5 милиарда долара от неизвестен малайзийски копувач.
Роботикс Сюприйм е робот, направен да прилича на яхта. За целта изглежда много дълъг и има заострен връх. Използва два големи EV3 мотора с гуми за да се движи. Отпред има цветен сензор, поставен така че робота да може да следва линия. Отзад има жироскопичен сензор, за да може да завива точно.
Dominator is a compact LEGO Mindstorms EV3 Box robot from the family of the Roller Coaster and Kiddo box robots. Similar to the previous two robots, Dominator also can move its front part up, down, left and right. This robot also has the same length of movement as its two predecessors of this type - 8 LEGO pins on the side and up.
The difference is that Dominator has fewer parts and has a perfect center of weight that allows it to use large attachments and lift heavy objects without threatening its stability. The movement on the X and Y axes has the same gear ratio. The light sensors are attached to the movable part of the robot which enables it to both follow a line and recognize the color of various object with height lower than 7 LEGO units.
