As with the two sensors we have covered so far, the color sensor can be used as a condition for the wait block, the switch block or the loop block. The color sensor, as well as the ultrasonic sensor, has several modes. Nevertheless, these modes are substantially different. While the ultrasonic sensor has two modes - one to work in centimeters and one in inches, the color sensor has three modes - one for detecting the color of an object, one for ambient light and one for reflected light.

When subscribing a user the platform is inspecting a few conditions and deciding what message should be send to the user.

Conditional Messages allows you to send an message to people for which specific conditions apply. For example people that have just enrolled and their subscription is active 

records.days_old=0, subscriptions.status="active"

The video shows why you should not build attachments such as "Crappy Active Attachment For SUV Box Robot". In the video one can see how the knob gear wheels start "jumping", once a force is applied to the lever. 

This video tutorial shows how the LEGO Mindstorms EV3 Rider Robot Motorcycle with Cart robot works. You can ride a friend with you.

This video tutorial shows how the LEGO Mindstorms EV3 Handlebar Chopper Motorcycle robot works. See how fast it is.

This video tutorial shows how the LEGO Mindstorms EV3 Shotgun Motorcycle robot works. The robot is a sligh modification of the Ninja motorcycle because it has assiting wheels

Devi is a stubborn robot. No mater how many times you press the button, it will press the button last. It if you press again, it will press again. Sometimes it will rotate and speak, but will again press the button, and will continue pressing until the end of times. 

One of the students' favorite LEGO Mindstorms robots. Have fun with Iqazator, moving over all kinds of obstacles as a real millitary tank machine. 

Althogh they are birds, Kiwis can’t fly, so they have adopted a running lifestyle.

Formula one is the most famous speed race, housing the fastest cars available to mankind.

The telephone game played with LEGO Mindstorms EV3 robots relies on the Color Sensors and the detection of colors. Sometimes the robots won't work. They could be influenced by a number of factors like the position of the sensor and the lighting in the room. This tutorial is a demonstration on how to account for and resolve this issue. 

In the Telephone is played with 2 or more robots and is extremelly funny. Each robot has a color wheel that can be rotated through the medium motor and a color sensor. The first robot on the left rotates the color wheel to a random color. The second robot must detect the color on the wheel and rotate its color wheel to this color. The third detects the color wheel of the second and so on. 

It is described in details in Lesson 4 of Level C2. Cooperation

Here is Mintonet. The robot is created to be used in pairs, but you can also build just one and practice your shooting with a box. The robot works with plastic balls between 5 and 7 cm. Using the ultrasonic sensor it can detect either its partner or a box and then it shoots. How many balls can you score?

Here is Iknathir - a LEGO Paper Plane Launcher. Just take a piece of paper, fold it to create a paper plane, place it on top of Iknathir, press the lever forward and the plane will be launched in the air. If you are not sure how to make a paper place, we got you covered! Just go to the following tutorial - How to make a simple paper plane. Feel free to experiment with the structure of the plane. How far can your plane go?

Forklift - it is a motor vehicle with its own drive, used to transport materials at short distances. It is mainly used for unloading works in warehouses, ports, or factories. The material to be moved with the use of a forklift is usually placed on pallets. 

Forklifts appeared in the 20's. of the twentieth century, they were produced almost simultaneously by several companies, including Clark (now Clark Material Handling Company) and Yale & Towne Manufacturing. 

Sweeper - a special vehicle designed for cleaning streets, pavements, and runways. The first sweeper is believed to be a construction patented on September 4, 1849 in the United States by CS Bishop, it was pulled by a horse cart. Until the end of the 19th century, 315 solutions for sweepers have been patented in the USA. The first sweeper with its own drive was patented in the USA in 1868. 

This video tutorial shows how the LEGO Mindstorms EV3 Ninja Motorcycle robot works. It's a nice demonstration with the robot moving forward, backward, and slightly to the left and right. 

Here is Turtle - a LEGO Mindstorms EV3 robot that is designed to look like a sea turtle (may look clumsy but it's not). It has two sensors - ultrasonic and gyro, capable of following its course and navigating through anything. It can even get "angry", if you annoy it too much.

Here is Comet. It is a fast LEGO Mindstorms EV3 Car robot that looks like F1 Racing Car. We've especially designed it to be controlled with the remote control to make it extremelly easy to download the program and start playing with the robot. It also has the option to "press the pedal" (increase the speed) with just the remote control. Check it out.
