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. 

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

Pinless attachments are smart and quick and could make a big differences between two robot constructions. In this video we are sharing a nice idea for a pinless attachment placed below the robot.

Vision is still one of the very few fields where a human being could outsmart a computer. Still. Colour/Light sensors are the cornerstones of implementing a smart LEGO Mindstorms robot that could at least partially do "vision". In this video tutorial, we are using the robotics sensor to detect loading and unloading of the catapult.

The Department of "throwing" is ruled by rubber bands. Impulsive power release in a short amount of time. In this video we are building an attachment that throws a ball and accomplishes the FIRST LEGO League 2012 bowling competition.

In this episode, we introduce a LEGO Mindstorms EV3 version of competition robot construction. It is a modular construction, with medium motor for additional attachments and two light or colour sensors for orientating on the field.

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. 

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.

Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms Competition robot without having the whole robot ready yet. We would be making mistakes, showing them and taking up the challenges right in front of your eyes. The first construction would not be perfect but we would eventually arive at it. 

Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms Competition robot without having the whole robot ready yet. We are continuing from part 1 where we finished part of the 'front' of the robot and we arrived at a construction that we didn`t like and would fix in this video lesson.

We are showing the first way we could position the motors on the robot construction. This seems to be challenging for many robot builders and that's why we are going to do it in a few different ways in the next few video tutorials from the series.

This third way of positioning the LEGO Mindstorms EV3 motors on the robot seems to be the most productive with the most advantages. We have named it "correct", but we completely understand there might be other even more efficient ways to position the motors on the robot.

This second way of positioning the LEGO Mindstorms EV3 motors on the robot leaves more space for the Mindstorms brick and for attaching a third motor. We are experimenting and showing the advantages and disadvantages of this particular construction.

The most stressed wheel in our system is the driven wheel. We've already fixed the problem with the driving wheel of the scissor mechanism and now it is time to look at the drive LEGO Mindstorms wheel. 

Based on your feedback we've build a course for introducing new students to the LEGO Mindstorms EV3 programming and construction. It is designed for school groups, competition teams and students alone in home that can get our feedback on their progress
