| + | ====== Exercise ====== | ||
| + | Goal: simple control algorithm. | ||
| + | Accessories: | ||
| + | * LEGO set | ||
| + | * instruction //QuickStart// | ||
| + | * software LEGO MINDSTORMS NXT | ||
| + | |||
| + | Output: Report | ||
| + | |||
| + | ===== Description ===== | ||
| + | What to do: | ||
| + | - build a simple mobile robot, and simultaneously | ||
| + | - design a simple control algorithm | ||
| + | - test the robot and the algorithm, | ||
| + | - evaluate and draw conclusions -> Report | ||
| + | Team organization: | ||
| + | * robot builder: 1,2 persons, | ||
| + | * algorithm development: 1,2 persons. | ||
| + | __Caution !__: | ||
| + | * use only blocks that you need | ||
| + | * do not take out too much blocks in the same time | ||
| + | * put all unused blocks [[https://ai.ia.agh.edu.pl/wiki/pl:mindstorms:lab:wyposazenie#rozlozenie_klockow_w_przegrodach|back in proper compartments]] | ||
| + | |||
| + | ===== Robot building ===== | ||
| + | (Builing team) | ||
| + | * Build a simple mobile robot i.e. according to //QuickStart//, your invention here is welcomed. | ||
| + | * Connect desired sensors on the front or side of the robot (i.e. sonar) | ||
| + | |||
| + | ===== Algorithm development ===== | ||
| + | (Control team) | ||
| + | * program simple control algorithms (1-2) | ||
| + | * use 1 or 2 sensors | ||
| + | * save project files | ||
| + | |||
| + | ===== Proposed Algorithms: ===== | ||
| + | |||
| + | ==== Patrol ==== | ||
| + | * robot drives on its (given) way (square, circle, triangle) | ||
| + | * repeats this way N times | ||
| + | * robot stops after finding an obstacle (touch or distance sensor) | ||
| + | * plays beep signal | ||
| + | * backs up | ||
| + | |||
| + | ==== Avoidance ==== | ||
| + | * robot drives straight | ||
| + | * after reaching an obstacle (use sonar) it tries to avoid it | ||
| + | * plays beep signal | ||
| + | * make a right turn | ||
| + | |||
| + | ==== Tracking ==== | ||
| + | * robot follows up a light source | ||
| + | |||
| + | ===== Additional Control ===== | ||
| + | * control the robot by voice signal (e.g. clapping) or touch | ||
| + | * example: one clap - start, two claps - stop | ||
| + | |||
| + | ===== Integration ===== | ||
| + | |||
| + | Test the algorithm on the constructed robot. | ||
| + | Please, remember that after uploading program to the robot you can disconnect USB wire and let it go on the desk or floor. | ||
| + | |||
| + | ===== Finish ===== | ||
| + | * Disassemble the robot, and put all elements in the proper [[https://ai.ia.agh.edu.pl/wiki/pl:mindstorms:lab:wyposazenie#rozlozenie_klockow_w_przegrodach|compartments in the box]] | ||
| + | |||
| + | __CAUTION__: do it slowly and carefully - damage is much easer during disassembly then while assembling. | ||
| + | |||
| + | |||
| + | ===== Report ===== | ||
| + | |||
| + | Prepare a short report describing what you have accomplished during 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. | ||
