Video tutorials, Courses, Materials and Programs

Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.  

Build a robot base to use in the course. You can use the robot base provided by us or you can build one yourself. 

Let us do a quick recap of the whole lifting mission and its solution

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. 

This is the 10 out of 10 version of executing 3 missions in a single run. It worked like a charm! 10 times. We push and collect energy units for the FIRST LEGO League 2022-2023 SUPERPOWERED Challenge competition.

Improving the construction for the World Robotics Olympiad missions. The improvement is in the position of the sensor and the size of the balls container. 

Notes on building the FiveMinuteBot

Try to add a touch sensor to the robot on your own.

DIfferent wheels and tires will result in different behaviour of the robot. That is actually pretty common sense. The real question is what is the influence. Would the robot make smaller deviations if it has smaller wheels or it will make larger deviations? The tires could also be quite dirty or brand new. Or the wheels could be attached in different ways. 

In this video tutorial, we would do a few experiments with the coefficients for the Integral compensation. There are actually two coefficients - "c" and "b"

This is a 10 out of 10 tutorial for a 3 missions run. The robot goes out of base and accomplishes 3 missions in a single run. It demonstrates the consistency and reliability of the robot and its program that uses sensors.

The challenge for this video is to program a menu that is controlled from the LEGO Mindstorms EV3 brick screen.
