Video tutorials

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.

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. 

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 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. 

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. 

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

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.

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. 

Next robot construction for holding and releasing balls from this container. In this video we discuss the improvements and how to use the chains to release one ball at a time.

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. 

Collect the humans and clear them from the rocket launching region. This is rather straightforward as a task, but it requires a little bit of thinking if you want to do it without manipulators.

Motors can be placed in opposite directions... opposite .. directions. Robo-builders might have difficulties imagining it so we have build one. One of the motors facing forward, the other backward. It is interesting how this robot turns.

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. 

Don't limit yourself to the box and think of different ways to lift the robot. 

Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets. 

How should an instructor use this course when working with students and a group of students in school

Previously we caught the Truck with two rubber bands. The next step was to lift it. For lifting we used the Medium LEGO Mindstorms EV3 motors. In this video we are extending the attachment so that we could catch also the Ambulance. In forth video we would explore how to release both vehicles after transporting them.

Where should you lift the robot? Especially if you don`t have the mission model that we are using

In this second part we continue with the next few tasks from the FIRST LEGO League (FLL) 2013 competition. Using the same rubber band attachment we lift the house and collect a few of the humans and cargoes.

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

Note for the teacher on how to organize the class to use different robot base constructions to accomplish the mission for lifting.

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. 

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.
