====== Lego Mindstorms Intro Lab ======


===== Description =====
Aim:
  * Getting familiar with equipment of NXT set: NXTbrick, sensors and motors. 
  * Getting familiar with programming of LEGO Mindstorms. 

Resources:
  * Hardware: NXTbrick, 3 motors, 4 sensors, connecting wires, USB wire, some Lego elements.
  * Software: LEGO environment.

===== Preparing =====

Pay attention to your workspace. Proper space arrangement is important. 
Make sure that Lego elements do not fall on the floor, get entangled with the keyboard etc.
Every team has a separate table.

**Special attention should be paid regarding elements location in the case, each element should be placed in a proper compartment!**\\
according to [[https://ai.ia.agh.edu.pl/wiki/mindstorms:lab:equipment| element arrangement in the case compartments]].\\
**Please, respect it for your and others convenience**

Assign appropriate roles in your team. Role assignment is important, you should choose persons for handling:
  * computer (programming) -> //Chief//
  * case (finding and delivering elements) -> //Mechanic//
  * elements (assembly, connecting elements) -> //Constructor//


===== Introduction =====
Read about laboratory  [[https://ai.ia.agh.edu.pl/wiki/mindstorms:lab:equipment|equipment]].

Find:
  * //Quickstart// (**QS**) - paper version will be distributed during exercises, and //User Guide// (**UG**),
  * elements:
    * Brick (control unit) - section D2,
    * sensors x4 - section D2,
    * motors x2 - section D1,
    * wires 2+4+1 - section A4.

**Before the end of the exercise, everything should be packed exactly in the same way as in the beginning**  


===== Connecting Senses =====
  * Put battery in to Brick.
  * Connect motors and sensors (QS:2, UG:7) __according to__ port numbers.
  * Turn on Brick.

===== I'm alive! =====
Test UI Brick:
  * run test programs "Try Me" (UG:16),
  * check sensors signals by "View" (UG:17),
  * look at UI full description (UG:20--21).

===== Connecting to the computer =====
  * Run LEGO application.
  * Connect Brick to the computer by USB.
  * Make new project.
  * Establish the connection between PC and Brick.

===== Programming =====
  * Construct a simple program, consisting of 2 elements in sensor/motor sequence.
  * Send program to Brick and test.
  * Repeat above using different sensors.

===== Robot building =====
  * Build a simple mobile robot, i.e. the one described in the //QuickStart//, use at least two motors.
  * Attach a single desired sensor (i.e. sonar) on the front or on the side of the Brick.

===== Logic =====
  * Use basic control instruction (i.e. conditionals) to make simple programs.
  * Extend the robot and the program to your liking - use your imagination.

===== Finish =====

After finishing the exercise __but__ __before__ leaving the lab, you should:
  * turn off the Brick and disconnect USB,
  * terminate the Lego application,
  * put the Brick, motors and sensors back to the case, unless at the beginning of the exercise the robot was already built - in this case you shouldn't disassemble it,  
  * close the case and clean up your work place.

===== REPORT =====

Prepare a short report describing what you have accomplished during the this exercise:
  * what was the purpose of the robot,
  * what sensors did you use and why,
  * include a photo of your robot,
  * include a screenshot of your program,
  * describe problems and difficulties you had.
