In Episode 58 we introduced you to an LEGO Mindstorms EV3 Modular robot. Mic Lowne wrote to us and had that robot remade, because it used too many blue lego pins and could not be build using one EV3 kit.
In part one we build an attachment that uses a rubber band to solve a competition challenge. The rubber band was released with the use of a motor. In this video we are removing the dependency on the motor and you could use the motor for other missions.
Learn how to set up LDD and Ldraw on your Windows computer. Get one step closer to building your first 3D LEGO Model.
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.
In this lesson I would like to show you how to build a LEGO Mindstorms competition robot and tell you how we have designed the construction used in the videos so far. Surely it isn’t perfect, but it is a good start.
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.
In this video we look at the way this robot uses the LEGO Mindstorms EV3 motors. How are they attached and the what the rotation of the motor is transferred to the attachments.
In part 1 of How to on Gears tutorial I introduced you to the basics of the gear systems. Now we are going to examinate gear systems with more than two gears and take a look at cascade gear systems.
Many teams have followed the same idea as the ELM team. To build a LEGO Mindstorms attachment for the robot and to lift the truck very lightly. In this way they could more the truck and place it in the special region. See what the ELM idea was.

We challenge you to build a construction of cardan joints that transfers power to a maximum angle. Submit your solutions to [email protected] and win an award. Use the challenge in home or in the classroom. Initial Deadline is 18 of Aprill 2015.
The energy accumulated in the construction is about 2-3 Joules. In this first video we ask the question "How can we keep the energy in the system". How many Joules of energy should we input from the motor in order to keep the energy in the system.
With the last few videos, we entered the math world. Why we do it and what to keep in mind
In this episode we will show you how to build the FiveMinuteBot. We will make a quick overview of this Mindstorm Robot.
In this tutorial we go through the VEX IQ Challenge. Most of the challenges are related with manipulating objects. The most common object used in competitions are balls. That is why we take a look at a simple mechanism that can be used for throwing a ball.
The length of the lever has a certain effect when hitting the ball. In this tutorial, I would like to discuss what it's the effect.
The topic of this tutorial is the purpose of a system of gears when throwing a ball.
How do you synchronise the two levers to move with the same speed, but in opposite directions?
