This robotics tutorial is about the different tools that you could use to collect the balls in a pipe on a FIRST Technical Challenge competition.
In this video tutorial we demonstrate the importance of properly shielding and protecting the light/color sensors of your LEGO Mindstorms Robot Inventor robots. These principles generally apply for all kind of robots. The problem is that external light sources from the venue could change the behavior of the robot - like have you ever been to a competition venue where the lighting just makes the robot behave in different ways? - well this tutorial is for you!
This video tutorial demonstrated the use of an active gear attachment for catching a wheel and pulling it. This is how we accomplish the Rowing Mission from the FIRST LEGO League 2021 competition. What you will learn is how such an attachment works. How you transfer power from the top of the robot where the motors are to the bottom of the robot where the catching mechanism is. Check out the building instructions for the attachment.
This video tutorial is for the Tire Flip Mission from FIRST LEGO League 2020 RePlay robotics competition. Flip missions are always some of the most interesting and challenging. In this tutorial you would learn how to build an attachment and accomplish a mission that requires you to flip a part, like flipping a coin. Most of the complexity for this mission is in the attachment and not the programming, but this is also way it works perfectly, every single time.
This is a 10 out of 10 tutorial demonstrating the accuracy of an active gear attachment that accomplishes the Treadmill mission from the FIRST LEGO League 2020 RePlay competition. When the robot is well aligned to the line before that it is easy for the robot to accomplish the mission. You will see how we make use of the friction of the wheel to rotate the mission model.
The bench mission was one of the most difficult we've encountered, especially when it comes to accomplishing the mission reliably. The goal of the mission is to push the bench down, lift part of it and leave 4 boxes at specific places. The whole concept of the mission is awesome. Here is how we did it:
The Slide mission the FIRST LEGO League 2020 is about the LEGO Minifigures sliding down the slide and the robot bringing them back to base. We must somehow bring then back do base. Do we push them on the Slide? Do we pull them? Or we could lift them. In this video tutorial we decided to pull the minifigures, but there is a catch.
In this FLL video tutorial we accomplish the step counter mission. We use a LEGO Mindstorms Robot Inventor robot. The idea of the mission is to control the robot in a very precise way so that it could slowly push on the mission model and accomplish it. In the tutorial we demonstrated exactly this slow push, but in a different way.
This video tutorial is about a detachable attachment. In various FIRST LEGO League competitions there are missions that could be accomplished with an attachment and when you accomplish the mission you must somehow leave the attachment along with the mission model. Probably as a support - most of the time it is as a support. But we've seen some pretty powerful concepts that include things like leaving a clock mechanism that will continue to work for 30 seconds accomplishing the mission.
10 out of 10 tutorials are about accomplishing missions in a reliable and repeatable way. In this video tutorials we accomplish the Step Counter mission 10 out of 10 times. We can push on the mission model, but if we push too hard we would lock it and there is no way back. So we use a slightly different approach. Check out the video to see how.
In this video tutorial we accomplish the Pull-Up bar mission from the FIRST LEGO League 2020. This is a 10 out of 10 tutorial for demonstrating the accuracy of the robot and the attachment. What you will learn is how a two part attachment works.
This is a 10 out of 10 tutorial demonstrating the accuracy of a Flip Attachment for the FIRST LEGO League 2020 Cell Phone Mission. The flip attachment flips a phone. Moves forward and flip it. This is a tricky business. It might not work. The trick is to approach the mission model from the right angle. In the tutorial you will see a demonstration and will learn how such a mission could be accomplished accurately with a LEGO Mindstorms Robot Inventor robot and attachment with gear wheels.
This 10 out of 10 tutorials demonstrates how we can accomplish a flip mission with a LEGO Mindstorms Robot inventor in a repeatable way. We manage to flip the tires on almost every try. You will learn and see how the attachment works and is able to push and flip the mission models.
The course is designed to be used with almost every remote controlled car. The process of opening the car will be different for different cars but there are basic principles that you could follow.
The goal of this lesson is for students to have fun with a new robot.
