Омусбот - ЛЕГО Майндстормс EV3 сумо робот
Можете ли да се сетите защо робота се казва "Омусбот"?
Роботът е направен като добра база за състезание по ЛЕГО Сумо за по-напреднали. Той използва два мотора, които са сложени отзад за повече сцепление докато се движи. Отпред има един цветен сензор, който засича крайната линия на полето. Над него има сензор за разстояние, който засича вражеският робот. Отзад робота има сензор за допир, за да засича ако бъде избутван.

Python program to align to a line with color sensors from LEGO Education SPIKE Prime
This program is developed with LEGO Education SPIKE App Python and is used to make the Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions align to a line with two color sensor. It's a mechanism we've used with EV3, NXT and now SPIKE.

Varna - a sumo Robot from LEGO Mindstorms EV3
Nice idea. Lift the other robot and throw it in the air. Not easy, but Varna is trying to do it. It's a quite powerful robot with small wheels and gear ratio of x3. This means the power is increased 3 time from the motor to the wheel.
Surely you can work with it and even improve it.

Сумо състезателен робот от ЛЕГО Mindstorms EV3
Това е пример за робот за състезанието по Сумо роботика и по-специално за RoboteX challenge. Повечето състезания по сумо за роботи имат изисквания за размера на робота, като за този робот изискването е 15 см х 15 см.
Състезанията по сумо са много забавни и интересни, тъй като целта е да се избута противниковия робот извън ринга.
