Have you seen how sumo wrestlers hunker down before the match?
If the sumo wrestler remains up, his opponent might easily take him down. When they hunker down, they position their center of mass, closer to the ground.

Does this mean that the sumo wrestler who attacks from a lower position will always win?
No! The sumo wrestler who attacks from a lower position has an advantage but does not always win.

Why?
One of the reasons could be that the size of the defeated wrestler is smaller. Size does matter in sumo wrestling. That is because bigger bodies can take stronger hits without being seriously affected. That is why sumo wrestlers eat a lot.

Does this mean that a sumo wrestler of a smaller size cannot take down a larger sumo wrestler?
Again, no! There are cases when smaller sumo wrestlers defeat larger opponents. Victory in sumo wrestling depends both on weight and on flexibility. Sumo wrestlers’ flexibility allows them to face their opponents without being pushed out of the ring.

Courses and lessons with this Tutorial

This Tutorial is used in the following courses and lessons

Robotics with LEGO - Level 3.0 - Security systems

This is the fifth level of the Robotics with LEGO curriculum for students in fifth to twelfth grades.

In this level students will learn how to work with data measured by the sensors. The concept of Algorithm is introduced and the programs perform calculations without knowing the values beforehand. The programming blocks transfer data between each other via data wires. The robots are designed to address the problems of security systems. Variety of alarm systems are built and the physical principles of different security methods are considered.

Lesson 4 - Seismic sensor

Introduction

In the following two lessons you will be the chief prison guard. Rumor has it that a gang of cake robbers is to be moved to your prison and they are planning to escape. In order to avoid a public scandal, the Mayor of the city has decided to invest in a new security system for the prison. Your job is to preserve the good name of your prison and protect the cakes in all pastry shops in the area.

Robotics with LEGO - Level 1.5 - Spy games

The second level of the Robotics with LEGO curriculum for students from fifth to twelfth grades.

Students build multiple robots with thread chains and become familiar with the physical concepts of momentum and center of gravity. The concept of gears, their use and basic constructions involving gears are studied.
The new concept of "condition" is introduced in programming. Robots are becoming smarter as they can make complex decisions on their own. "Spy robots" follow their targets and avoid being noticed. This level introduces the light sensor which the robots use to recognize the colors of the objects they are looking for. Robots can stop on a black line and follow a route marked with a colored line on the floor.
The spy's most complex mission in the end of the level is to turn into a sumo wrestler and defeat any other robot in the ring.
