Frequently Asked Questions

• Who has created the Tapster bot ?

  • Have a look on Tapster

• Why use Appium?

  • Appium has been created by the same person who created Tapster
  • Appium is quite powerful is we want to deal with mobile native or web apps with only one script
  • Appium makes possible the retrievement of coordinates of contact points during the calibration process

• How Appium can get the contents?

  • For Android, Appium will use a bootstrap.jar and the UI Automator
  • For iOS, Appium will use a Web Driver Agent Runner which will use XCUITest

• How the bot and the computer can communicate?

  • The bot possesses an Arduino Uno board
  • The bot and the computer are linked with a USB connection
  • The Firmata protocol is used so as to make the communication. It has been flashed in the Arduino board, and embedded with Johnny-Five in the computer side.

• I sent a "tap" command to the bot: it moves to (x,y) but did not hit the screen, why?

  • Check the Z value defined in you calibraiton used fiven as a parameter to the server
  • The system will use the lowest value between the Z of the contact point, the Z of the point1 and the Z on the point2, so you can make contactPoint.z lower in this JSON file

• Where are placed the servomotors on the bot's top plate?

  • You can have a look on this picture

• What kind of things should display the calibration app?

  • You can have a look on this picture

• How can I be sure I have calibrated the bot to a device?

  • You may have some outputs on your terminal like these

• How can I be sure I have calibrated the arms of the bot?

  • You may have some outputs on your terminal like these

• I think my calibration data have been fucked up, what should be the format of these values?

  • You can have a look on this file

• How can I test quickly the HTTP requests the robot can deal?

  • You can have a look on this file

• How can I reach my bot available at xxx.xxx.xxx.xxx:yyyy?

  • Define the IP address and the port in the client you use
  • Run the bot's server with the dedicated parameters (--address and --port)

• I cannot start the server.js script, an exception related to johnny-five or the board occurs.

  • Be sure you can use the port on which the robot has been plugged.
  • You can run the Arduino IDE, and get the port in use. For example on Ubuntu it may be dev/ttyACM0
  • Then according to this post, you may allow the use of this port using the commands:

    sudo usermod -a -G dialout <username>;
    sudo chmod a+rw <port>;

• And if my Tapster robot screams "Exterminate!"?
