| + | ====== 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. | ||
