| - | Eesmärgiks on koostada programm, mis täidab kirjeldatud ülesannet. | + | The goal is to write a program which is able to perform tasks described below. |
| - | ===== Soojendusülesanne | + | ===== Warm up exercise |
| - | * Alalisvoolu mootori juhtimine digitaalplaadiga. Vajutades nupule | + | * Controlling the DC motor using buttons of a User Interface module. By pressing |
| - | ===== Algajale | + | ===== For beginners |
| - | | + | - DC motor control. Movement of a robot is simulated, by using DC motor and touch sensors. Touch sensors are the buttons |
| - | | + | - DC motor accelerates when S1 is pressed down and holds achieved speed when the button is released. By holding |
| - | - Radar. | + | - Servo motor, the servo motor is controlled via the buttons of the User Interface module. By pressing down S1 the servomotor moves one step to the right. By pressing down S3, the servo motor moves one step to the left and S2 makes the servo motor to move to the initial |
| - | - Samm-mootor. Samm-mootor pöörleb iga nupule S1 ja S3 vajutamise järel 10 sammu, vastavalt päri- ja vastupäeva. Nupp S2 katkestab pöörlemise viivitamatult. | + | - Radar, UH sensor based radar is simulated. Sensor is installed to the lever of the servo motor. The lever of servo motor is moving constantly form one extreme position to the other. If there happens to be an object in closer range than 0,5 meters of the sensor, then the servo motor is stopped for 5 seconds and by signaling a LED that detection of the object is announced. After 5 seconds of flashing of the LED, scanning continues. |

| - | ===== Edasijõudnule | + | ===== For advanced |
| - | - Alalisvoolu mootor kiirendab S1 nupu allavajutamisel ning hoiab S1 nupu vabastamisel saavutatud kiirust. S2 nupu allavajutatud asendis hoidmise ajal mootor aeglustub sujuvalt. S3 allavajutamisel peatub mootor | + | |
| - | - Objekti jälgimine. Kasutades ultraheli kaugusandurit, mis on paigaldatud servomootori hoovale, peab servomootor jälgima mööduvat objekti. Mootor pöörab vastavalt objekti liikumisele nii, et objekt oleks kogu aeg anduri vaatevälja keskel. | + | - Tracking an object. By using ultrasonic distance sensor, which is installed |
| - | - Samm-mootor säilitab mootori viimase asendi pärast iga jada muutust. Uue jada aktiveerimisel kasutage muutujat, et jätkata liikumist täpselt viimasest mootori asendist. | + | - Using a stepper motor, make a second dial of the analog clock. The motor must be make exactly 60 steps on one complete rotation. Movement should be stepped and not smooth. |
| - | - Kiirendus. Programm võimaldab muuta samm-mootori kiirendamist/aeglustamist. Kasutage lineaarseid kiirusekaldeid, | + | - Acceleration, |
| - | - Koostage alalisvoolu mootorile | + | - Design a PID regulator (or its simplified form) for a DC motor. NB! This exercise demands a motor with feedback (encoder). |
| + | - DC motor. The DC motor is controlled via the buttons of the User Interface module. By pressing down S1 the motor moves one step (x encoder pulses) to the left. By pressing down S3, the motor moves the same amount of steps to the back. The motor rotates exact amount of a predetermined steps, regardless of a torque applied to the shaft (in the case where applied torque is less than the engine maximum output torque). | ||
