Level A2. "Space exploration". Robotics with LEGO

The second level of the Robotics with LEGO curriculum for students in second, third or fourth grades.

A new sensor is introduced - the Ultrasonic distance sensor can help the robot avoid obstacles. Students work with new concepts like loop, degrees and medium motor. Robots can now do two different actions at the same time - while solving missions on a field, the third motor clears detected obstacles. The first robot with chain-treads is built.

How does Crone, the LEGO Mindstrorms EV3 Crane Robot work?

LEGO Mindstorms EV3 Crane robot is used to lift, move and load cargo on a cargo truck. There is a mechanism for grabbing a cargo load (eg a blue ball). Crone is also a tower crane and there are balancing wheels on the opposite site of the grabbing mechanism. It was an ultrasonic sensor.

Geldautomaat, a LEGO Mindstorms EV3 ATM robot

Geldautomaat, from German, means ATM.

This is the last robot from the 3.0 course book in the LEGO Mindstorms Curriculum. It uses a Touch Sensor to sense if there is a card inside. When touched, a Medium Motor starts spinning and pulls the card inside its chamber, where a Color Sensor reads the data from the card.

NOTE: There is a step, where you have to place the "credit card" inside. It may seem unnecessary and pointless, but otherwise, you will not have proper support for the next steps and the construction will crumble.

Extracting the logic for finding minimum an maximum into a new block

One of the smartest things you could do in any software program is to extract logic in small reusable, simple, understandable units. In EV3-G these are called Blocks and we are going to extract the logic for finding a minimum and maximum for each of the sensors in a new block.

EV3 basics course. Color Sensor. Detect line (part 1)

Very simple and basic introduction to the color sensor in the LEGO Mindstorms EV3 set. The first program is to stop at a line. Then we can move from stoping at line to counting lines and even more complex tasks.

Example solution for the tasks in lesson 1 from course 4.0

This program is the most basic version of the game played with EV3 Kinesthetic and Memory Game. For the program to work correctly, there must be two touch sensor modules attached to port 1 and port 2. The other modules are not required from this program.

WRO Junior-High 2014. Sputnik. Collecting objects. Part 1

Starting with the World Robotics Olympiad 2014 Junior-High challenge we first catch the object on our path. We discuss a good mechanism for catching and lifting balls that can do two movements with one motor.

BigDaddy Motors Position - first way to position them

You can position the motors on the construction in a number of different ways. We are exploring the advantages and disadvantages of each of them. These are building instructions for the first way to position the LEGO Mindstorms EV3 motors.
