In episode 11 we looked at one of the most important topics for the competition - calibrating the light sensors. In this video I would like to show you how to use a more programmatic approach. This means letting the robot do the calibration on its own. Automatically.
This video lesson is a revised version of Episode #1. Matt Gipson requested it in a comment. Using the EV3-G software we have developed a very simple program for following a line with two LEGO MINDSTORMS color/light sensors.
Starting leJOS might be very problematic, since you need to install a few libraries and make some configurations. In this video tutorial I am showing a step-by-step guide on how you could install leJOS on your Ubuntu Linux. And it is quite easy.
First time programming the motors of the robot using the EV3-G software installed on a computer. We would explore how to move forward/backward and turn with the robot.
There is no block for programming the Ultrasonic Sensor in the retail version of the LEGO Mindstorms EV3 software. In this video tutorial we will show you how you can download & import such blocks in order to use the sensor.
Probably the robot I like the most from this series of five robots. See the video to understand why and what is interesting and special about this robot.
This video discusses the fact the robot requires a few more parts that are available in the LEGO Mindstorms EV3 robotics sets. We have a number of other constructions that require less parts, but for this particular robot construction we have decided to go beyond the standard sets, cheaply buy a few more parts and build a whole box robot with them.
This is a course for beginners, but the tasks would be interesting and for more intermediate students. We do not expect any previous knowledge from you except for how to divide numbers and use a computer.
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.
An advanced but understandable description of how to program the mindstorm robot to move in a regular n-gon like pentagon, hexagon etc. (Yes, we know math). We have also included notes on the used formulas. A must see for each of you who would like to master the robot movements.
In this video tutorial we will show you three ways for making your robot stable on the field. We will present each one of them with their advantages and disadvantages - it's up to you to choose which one is the best for your case.
We continue the discussion of the Robot Design category from the FIRST LEGO League Competition. This time we stop on the programming - how to evaluate the programming of the team during its preparation for the competition.
Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms EV3 Competition robot without having the whole robot ready yet. We are continuing from part 2 where we finished the 'front' of the robot and now we will extend it so that we could also attach the rear part.
As an extension to the previous video we talk about the Hi Technic Color Sensor again.
The third robot has the brick and motors placed vertically. This is quite unusual and difficult, but the construction is very powerful because it saves space.
