World Robotics Olympiad (WRO) 2014 Elementary. Review of solutions with explanations

This playlist of videos is about World Robotics Olympiad 2014 Elementary Challenge. Modules are positioned on different places on the fields. The robot must collect and bring the module near each other. The it must lift them and place them like they are ready for "rocket launching". In the mean time Humans must be collected and returned to the safety zone. We build a robot with a grabber and in interesting program for solving the missions.

BigDaddy Competition Robot (Part 4 - Complex Transfer of Power in a Triangle)

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.

MotoCar Bot - LEGO Mindstorms Robot that is kind of like a forklift

"How do you build a forklift using only gear wheels and levers without a rake"... Ok, we would admit that is a difficult question. It even sounds difficult. So let's start with something easy. A LEGO Mindstorms EV3 robot. It lifts objects in the air. It uses two gear wheels that work together and then move in different directions and are placed perpendicular to each other... This sentence kind of got difficult again... Let me try again.

Follow the building instructions with these 70+ steps and you will have a very nice robot and you will learn a simple trick of how to use gears and change the directions in which they rotate.

The First Robot

Now it’s time to test but we see that the robot which will choose a color does not have a program. That is why we have prepared a block which will choose a random color!

How to use the Ultrasonic Sensor with the Catapult built from EV3/NXT (Part 5)

This video lesson shows a very interesting specific example on how to use the LEGO Mindstorms EV3 Ultrasonic Sensor. The sensor detects if the catapult is loaded or if we have just fired an element. At the end of the lesson I also offer an interesting challenge that you could use in your classroom or at home.
