'''Lego Mindstorms EV3''' is the third generation from [[LEGO]]'s [[Lego Mindstorms|LEGO Mindstorms]] robotic theme. It is a successor of the [[Lego Mindstorms NXT 2.0]] second generation series. The "EV" designation means that it's an evolution of former NXT series. It was officially announced on January 4, 2013 and was released in stores on September 1, 2013 and the education set is released August 1 2013.<ref name="EV3-Press-20130104">[http://www.lego.com/en-us/mindstorms/news/2013/january/announcing-lego-mindstorms-ev3/ Official EV3 Press Release]</ref>

==Overview==
The biggest change from the [[Lego Mindstorms NXT]] and [[Lego Mindstorms NXT 2.0|NXT 2.0]] to EV3 series is the technology improvement of the programmable brick. The main processor of the NXT was an [[ARM7]]-based microcontroller, whereas the EV3 has an [[ARM9]]-based processor running [[Linux]]. A [[USB]] connector and Micro [[Secure Digital|SD]] slot (up to 32GB) are new to the EV3. It comes with 5 models: EV3RSTORM, GRIPP3R, R3PTAR, SPIK3R, and TRACK3R. [[Lego]] has also announced that they will release instructions online to build 12 additional models from the set; ROBODOZ3R, BANNER PRINT3R, EV3MEG, BOBB3E, MR-B3AM, RAC3 TRUCK, KRAZ3, EV3D4, EL3CTRIC GUITAR, DINOR3X, WACK3M, and EV3GAME.<ref name="EV3-FAQ">[http://www.lego.com/en-us/mindstorms/support/faq/ Official EV3 Frequently Asked Questions; Lego.]</ref>

The EV3 Home (31313) set consists of: 1 EV3 programmable brick, 2 Large Motors, 1 Medium Motor, 1 Touch Sensor, 1 Colour Sensor, 1 Infrared Sensor, 1 Remote Control, cables, USB cable, and 585 TECHNIC elements.() <ref name="EV3-FAQ"/>

The Education EV3 Core Set (45544) set consists of: 1 EV3 programmable brick, 2 Large Motors, 1 Medium Motor, 2 Touch Sensor, 1 Colour Sensor, 1 Gyroscopic Sensor, 1 Ultrasonic Sensor, cables, USB cable, 1 Rechargeable battery and many TECHNIC elements. <ref name="EV3-FAQ"/>

There is also an education set for the EV3 like the NXT. The core set contains 541 Lego elements including the EV3 brick, 2 large motors, 1 medium motor, an ultrasonic sensor, a pair of touch sensors, a gyro sensor and a colour sensor. The expansion set, which could be bought separately, contains 853 Lego elements. However, these two sets combined aren't capable to build most [[robots]] of the retail set unlike the education set of the NXT when the base set and the resource set can be combined to build any retail robots. The set is released 1 month earlier than the retail set and that is the August 1 2013. Robots that can be built by the core set itself are the EV3 educator robot, the GyroBoy, the Colour Sorter, the Puppy and the Robot Arm H25. Robots that can be built with the expansion set are the Tank Bot, the Znap, the Stair Climber, the Elephant and a remote control. Another robot that can be built with a pair of core set and an expansion set is the Spinner Factory.

==Compatibility==
All NXT sensors, motors, and building elements work with EV3 and are recognized as NXT sensors/motors when plugged in. EV3 sensors do not work with the NXT but EV3 motors do. NXT can be programmed with the EV3 software but lacks some software features. When you use the EV3 software to program the NXT, you must download extra programming-blocks, as the UltraSonic sensor. EV3 cannot be programmed with NXT software. <ref name="lego_readmore">{{cite web | url=http://mindstorms.lego.com/en-us/News/ReadMore/Default.aspx?id=476781 | title=LEGO MINDSTORMS® EV3 Frequently Asked Questions | publisher=The LEGO Group | work=Lego.com | date=15 March 2013 | accessdate=1 October 2013 | quote=Q: Is EV3 backwards compatible with NXT hardware? A: Yes. You can program your NXT intelligent brick using the new EV3 software. However not all software features are supported by the NXT intelligent Brick. You cannot program your EV3 programmable brick with the NXT Software.}}</ref>
