  1. Introduction to Robotics Day4

  2. Basic Programming 1 • Test out your robot • Use the following programming steps activate the Demo Mode. • Test your robot’s movements ON THE FLOOR PUT THE ROBOT ON THE GROUND!!!!

  3. Basic Programming 2

  4. Brick Parts - Front Brick Name USB Connection Attached Wireless Connection Battery Level Left, Right, Up, Down Used to navigate through the contents of the menus. Back Used to reverse actions to abort a running program and shut down the unit. Center Used to accept various questions, shut down, select desired settings, select desired program blocks.

  5. Brick Status Light • RED • Startup, Updating, Shutdown • RED Pulsing = Busy • ORANGE / ORANGE Pulsing • Alert, Ready • GREEN • Ready • GREEN Pulsing • Running Program • The Brick Status Light can also be programed to show different colors and to pulse when different conditions are met.

  6. Brick Parts -Sides Computer Connection OUTPUT PORTS (Motors) B & C - Large Motors D - Small Motor INPUT PORTS (Sensors) 1 2 3 4 PC D C B A USB PORT SD CARD SLOT SPEAKER

  9. Command Block Palette Time Used to give any command a length. Sensors Sound Up to 12 sounds pre-programmed into the Brick. Images Can display different images on the screen Light Can light up in 3 different colors Trash Can Deletes the selected command Motors (L) Small Motor (R) Large Motors

  10. Clock / Time • All of the commands that you give your robot need a time range. • If you want your robot to move in a certain direction, produce a sound, display an image of, flash / change the color of its lights, it must be told for how long to do it.

  11. Large Motors - Steering • Controls the two large motors generally used for mobility and steering in mobile robots.

  12. Program Editor START PROGRAM Run for 2 seconds The motors connected to ports B & C will spin the robot in a CCW circle END PROGRAM • All commands of a program need an ACTION and a length of TIME.

  13. Ultrasonic Sensor • An ultrasonic sensor works with waves and often it is used in applications for measure distance between a robot and surrounded objects. • Thesensor emits sound waves and receives their echoes to detect and measure the distance from one or more objects. • The Ultrasonic Sensor is designed for a wide range of applications including measure the distance, detection, or traffic monitoring. • Features • distance measure up to 250 cm (~100-inch); • +/- 1 cm (+/- 0.4-inch) accuracy; • recognize other ultrasonic sound;

  14. Color Sensor • Used for object detection, follow a line, sorting objects, or detection of a normal or reflected light. • The digital EV3 Color Sensor could be used for applications to detect • the absence of color, • the difference between colors, • up to seven different colors, • the light intensity. • Features • detection for up to seven colors; • detect the absence of color; • it works in ambient light; • sample rate of 1 kHz; • Auto-ID is built into the EV3 Software;

  15. Gyro Sensor • Used as assistance in stability of a robot. The mechanical system can determine the rotation and robot orientation on several axes giving the possibility for users to measure the angles and design robots with proper navigation systems. • Exploring the features of EV3 Gyro Sensor can be build balancing robots with high accuracy in movements. • Features • measure rotational motion and changes in its orientation; • +/- 3 degrees accuracy; • maximum output of 440 degrees/second; • sample rate of 1 kHz;

  16. Touch Sensor • A simple and accurate sensor that can be used in a wide range of applications like games or control systems. • With a button in front and an integrated counter, the sensor that can be used in a wide range of applications like games or control systems. • Button and a counter for press/release actions of the button. • This sensor is usually used for start/stop control systems, games like maze-solving robots, and many other applications. • Features • cross-axle hole on button;

  17. Activities • Complete the following tasks from the instruction book. • Divide up the tasks within your group. • You will be evaluated based on the amount you contribute to your team. • Follow all the directions carefully and program the robots as described. • Feel free to experiment some more with the programs and construction of your robots. • Show the teacher all of your successes and accomplishments.

  18. Activities • Each person in the group should build one of the following and program another _ • Ultrasonic – Gyroscopic – Color Sensor • Pages 42 – 47 & 48 – 53 & 69 – 72 • Medium Motor • Pages 54 – 68 • Color Sensor – Touch Sensor • Pages 73 – 76 & 77 – 80 ALWAYS TEST ROBOTS ON THE FLOOR!
