LEGO MINDSTORMS EV3

The robot can move with different speed by applying different power to the motors. It will most of the time make smaller deviations when it moves slower. But you can't just move with a power of 10 all the time. This is a way too slow especially for competitions like FIRST LEGO League or World Robot Olympiad. In this video tutorial I would like to discuss the balance between motor power and robot movement error, how does the battery influence the power of the robot and to conduct an EV3-G experiment that will record the values of the Gyro Sensor along with the current power. 

The 90-degree turn of the robot is different from 90-degree turn of the motor!

To move a motor, we set the speed at which we want to move, the amount of time we want it to move and the way we want it to stop. There is a command that allows you to set all these parameters at once.

We will demonstrate the common mistakes students make when building a robot.

How can we display a message and an unknown name in one notification? For example, “Hello, [student’s name], how do you do?” This is done by using a text block.

Accomplishing many tasks with a single attachment for the FIRST LEGO League (FLL) 2013 competition. The attachments are using many rubber bands. What is interesting is that it collects/lift/triggers many things at the same time. This is how you could save time and parts during a competition.
