Introducing the all New LEGO® MINDSTORMS® EV3 The EV3 is the 3rd robot making kit of the LEGO® MINDSTORMS® series and was cooperatively developed with MIT- Massachusetts Institute of Technology. With its new sensors and capabilities, not only can you make more capable robots, but you can also run advanced scientific experiments in the class room using its software. The LEGO® MINDSTORMS® EV3 has been improved dramatically with a faster processor, additional output ports, programming improvements and a newly added USB port, micro SD card slot, and auto-ID function. You are now able to program directly on the “brick” and use a combination of an IR, Bluetooth, or even a smart phone to wirelessly control your creations.

LEGO MINDSTORMS® EV3 Frequently Asked Questions Q: What is LEGO® MINDSTORMS®? A: LEGO® MINDSTORMS® is a programmable robotics construction set that gives you the power to build and program your own LEGO® robots. Q: What does EV3 stand for? A: This is the third generation of LEGO® MINDSTORMS® platform and the “EV” stands for evolution, hence EV3.

Q: What is a programmable brick? A: The programmable brick is the intelligent programmable microcomputer that controls motors and sensors, as well as providing wireless communication through Wi-Fi and Bluetooth. Q: I have a LEGO® MINDSTORMS® NXT set already – will a conversion kit from the LEGO® MINDSTORMS® NXT set to the LEGO® MINDSTORMS® EV3 set be made available? A: No, a conversion set will not be made available. Q: How do the EV3 sensors compare with the NXT sensors?

A: A lot of improvements have been made. Some of the more notable are: • The EV3 Color Sensor can detect 7 colors (and no colors) as opposed to the NXT Color Sensor which can detect 6 colors • With the EV3 Color Sensor you have Reflected Light mode which removes background light. • The EV3 sensors can return new values 1000 times/sec where the NXT sensors only return new values 333 times/sec.

Q: How is the EV3 differentiated from the NXT?

• In this model, we will read the Accelrometer on-board Sense HAT. We will determine the motor speeds for the EV3 robot by using the acceleration data read from the Sense HAT Accelrometer. A network connection would be setup between the Raspberry Pi device and the EV3 robot for data exchange. • In this model, we would use the communication blocks of LEGO MINDSTORMS EV3 to recieve the data sent by Raspberry Pi. The data received will be used to drive the motors of the EV3 robot. This example would help you learn the following.

Working Principle of Robot movement control In this section, we will discuss how the acceleration data can be used to control the movement of the robot. The 'pitch' and 'roll' value corresponding to a given position of Sense HAT can be mathematically determined from the accelaration measured from the Accelerometer on-board Sense HAT. We map the 'pitch' and 'roll' movement of the Sense HAT to the movement of the EV3 robot. The 'pitch' would represent the forward and reverse movement of the motor whereas the 'roll' would represent the sideward movement of the robot. The mathematical equations required to convert the 'pitch' and 'roll' values to linear speed of the robot are realized using a MATLAB function block in the Simulink model for configured for Raspberry Pi. A communication link for data exchange is set up between Raspberry Pi and the EV3 brick. The linear motor speed derived from the pitch and roll values is sent over UDP from Raspberry Pi to EV3.

EV3 will receive this data and use it as input to drive the two motors. Task 1 - Familiarize with Controlling EV3 using Host model example shows usage of Dashboard widgets in a Simulink model running on a Host machine to control the movement of a EV3 robot.

The communication between EV3 and the Host is over UDP. Complete this example to get familiarity with setting up a communication link between EV3 and a Host model for data exchange. Task 2 - Install Simulink Support Package for Raspberry Pi You need Simulink Support Package for Raspberry Pi to run Simulink model on Raspberry Pi hardware. Install Simulink Support Package for Raspberry Pi.

Click the link to 2. Complete the example in Simulink Support Package for Raspberry Pi you just installed. Task 3 - Familiarize with Sense HAT Accelerometer example shows usage of the Accelerometer on the Raspberry Pi Sense HAT.

The acceleration data is used to auto-rotate an image displayed on the LED matrix of Sense HAT. Complete this example to get familiarity with the usage of Accelerometer.
