Video tutorials

How to search for an unknown value with the fewest possible tries.

In the video we improve on the robotics mechanism for pushing the different blocks out of the robot container. We continue from the previous video.

The final way for lifting our box robot is by using a scissors mechanism. In this Episode, we would discuss the benefits and advantages of this mechanism.

In this video we look at the robotics mechanism for dropping the different blocks into the different region on the World Robotics Olympiad 2013 field. 

We continue from part 4 where we made a controlled experiment to transfer power from a Mindstorms motor to the rear wheels. The construction was too complex and inefficient and in this video lesson we are improving it by lowering the differential and removing all gear wheels from this LEGO Mindstorms EV3 Competition robot. 

This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the M06. SPACE STATION MODULES mission 9 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission. It moves forward and attaches the space station module with the space station. 

We continue from part 3 where we finished part of the 'rear'. Power is transfered from a motor to the wheels but having about 16 gear wheels makes it more than complex for this LEGO Mindstorms EV3 Competition robot. 

The video shows why you should not build attachments such as "Crappy Active Attachment For SUV Box Robot". In the video one can see how the knob gear wheels start "jumping", once a force is applied to the lever. 

Extend the previously build attachment for the FIRST LEGO League (FLL) Nature's Fury competition so that we can move the Truck and Ambulance up and down. 

We have the following behaviour expectations from you during this course:

You ask the question.
You will probably err before you succeed.
You should work as a team. Share solutions with others, help them and allow them to help you.
When the teacher speaks, this is important to everyone.
You should read your lesson before you come to class.

It has been a long road with the last 8 BigDaddy competition robots video tutorials, but we finally arrived at the Differential Lock. 

After several questions about the use of the LEGO Mindstorms NXT Light Sensor with the EV3 software, we have decided to go through this problem in this video tutorial and pay special attention to the Raw Sensor Value Block.

Based on a request from Abdulah we decided to build a tutorial on how to use Hi Technic Color Sensor and EV3-G Software. There is a special block imported in the software that helps you use the sensor.

Detecting direction using the camera in Scratch is a very useful tool for controlling our sprite using movement. Now you will learn how it functions and how to use it!

In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow

We will build the EasyBot quick robot and will explain how to follow building instructions.

Sometimes you could just throw a ball from base and solve a competition. Or at least many teams think so. In this video we would explore a very simple attachment for throwing balls from base. Can you use this for other missions? - we think so. Check out the video. 

All worked as expected, up until know because the robot got lost. This happens when we turn right and the line does not continue to the right. Now the robot must somehow understand that it is "lost" and escape.

Arriving at a final solution. There is still room for improvement on using the Mindstorms Ultrasonic Sensor for aligning to walls, but we hope the whole five videos could give you a good idea of how to start with a problem and reach a solution.

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M09. STRENGTH EXERCISE. I could think for a couple of missions in previous years that require lifting a heavy object. Let's see how this mission could be accomplished. 

In the final video we explore how to trigger the release of the attachment with just a rubber band. The release is triggered with a gear wheel that rotates in a specific way. This saves speed, does not require additional LEGO Mindstorms motor and is precise enough for a competition. 

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.

Specific challenge on programming the robot to move as a Yo-Yo

Part three of the Catapult series is about loading the catapult automatically. We use a gear system with a medium complexity along with a very interesting "clutch" developed with parts entirely from the LEGO Mindstorms NXT kits. As a result, at the end of the video, the Catapult automatically loads and fires.

Sometimes when we are working with sensors it is important that the time between two consecutive samples is the same. This will make each sample equally important and independent of how much time it took to take it. In this video tutorial, we would use the EV3-G timer block to make a "WaitForTick" program where the time between each sample of the EV3 Gyro takes exactly 0.02 seconds. 

Based on a request we are showing the robot construction with two rear motors instead of a differential. In this way, as a construction, it is closer to more students, but much more challеnging for programing. 

In this episode I would like to show you a way to solve the FLL 2012 Medicine mission using an LEGO Mindstorms NXT Ultrasonic Sensor and a system of gears that converts circular motion to linear.
