You are not using sensors?! You are positioning the mindstorms robot only by moving forward, backwards and rotating it. That`s one of the BIGGEST mistakes teams make on the FIRST LEGO League competitions. In this video we are showing a robot with chains and how imprecise are the results are when you are not using sensors.
We are describing the Warm gear in this video. This worm gear does most of the magic of controlling how the different gear wheels move on the different axles.
In this third video we show some of the tricks in building this Multi-axles mechanism. Things you could learn from an use in your next constructions.
We start a course for following a line with crosses and gaps. This is a challenge that one of the users at FLLCasts.com was trying to accomplish and asked us for advice. We present the whole challenge to you step-by-step. But first, let's also see the whole run of the line following algorithm. With this course, we also do an introduction of using State Machine as a programming pattern.
Football with robots could be quite fun. Football with LEGO Mindstorms robots is one of the popular categories for competitions with LEGO Mindstorms Robots.
We've recently received a number of question on how could the SUV box robot be charged. The answer is simple - you detach the back pane. The question and topic of detaching modules from a robot and attaching them again is really interesting and powerfull and yet not very often implemented in many robots.
This FRIST LEGO League video tutorial is about he Boccia Share mission from FIRST LEGO League 2020 RePlay competition. In the tutorial we demonstrate how to push on a lever to release a mission model part - in this case a box. You have the choice before the competition to cooperate with the other team and to decide if you are going to do the blue or the red box.
Similar to the tutorial for the LEGO Education SPIKE Prime this tutorial again accomplishes the cell phone mission. The mission is to flip the phone and is part of the FIRST LEGO League 2020 RePlay competition.
Given the large number of gear wheels and axles in each EV3 and NXT sets there are many possibilities for building gear mechanisms. We are developing something like a gear box that has different axles that could all turn in different directions.
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.
In this video tutorial we use an active attachment with a gears, built only form LEGO Mindstorms Robot Inventor parts, to accomplish the FIRST LEGO League 2020 Treadmill mission. The goal of the mission is to rotate the mission model for a couple of seconds so that a pointer makes a half circle rotation. What you will learn is a good principle to approach such missions.
In this episode I will show you how to program the touch sensor part of the LEGO Mindstorms education robotics sets. I have given answers to questions like - how the touch sensor works or how you can use it.
In the previous part of the video lesson we showed how imprecise a chain LEGO Mindstorms robot could be if its positioning does not rely on sensors, but only on the use of move block. In this tutorial we will show the same thing, but using robot on tires.
In Episode 58 we introduced you to a LEGO Mindstorms EV3 Modular robot. In this tutorial, we show you how we reached that construction. We start from a construction found on the Internet and take you through the process of examining and improving it, till we reach a more stable and reliable robot.
We have previously aligned to lines with the Color Sensors. In this series we are doing the same program, but with Ultrasonic Sensors that are aligning the robot to a Wall.
