  9. Accessing the Configuration Utility

  10. Starting the Configuration Utility

  11. Configuring the Samantha Module The SSID is case-sensitive and contains only letters Click “Save” to write the configuration to the flash drive

  12. Copying the Configuration to the Module http://www.youtube.com/watch?v=RrLJVLhiI-w&feature=youtu.be

  13. Copying the Configuration to the Module

  14. Starting the FCS

  15. Setting up Controllers Pressing “OK” will lead you to an empty FCS screen.

  16. Connecting Robot to Computer When both the NXT and Main Switch are turned on, the Red Power light should be solid, the white Wifi light flashing on and off, and the blue NXT light solid.

  17. Selecting your Robot You want to press this “Choose” button because that is where your controller is currently registered.

  18. Selecting your Robot If nothing shows up on this list make sure the computer you are using is connected to the same wireless network as the robot. Also, be sure both your main power switch, and NXT are turned on.

  19. Connecting for the FIRST time When connecting for the first time, the module will not recognize the computer attempting to pair. As a security and safety precaution, you are required to press the red button on your Samantha to confirm the pairing request. • This should only happen when: • Connecting to a computer for the first time • Connecting to a computer after the robot was connected to a different network (after competitions) http://www.youtube.com/watch?v=5irvtBmVq5g&feature=youtu.be

  20. Successful Connection After successfully connecting, the status for your robot should either be yellow or green • Yellow Condition: • No Program is running • NXT or Main battery is low: check the voltage • If the main battery is low, the Red power light will also begin flashing • GreenCondition: • Program is either actively running or waiting for command from the FCS • NXT and Main battery voltages are nominal

  21. Useful Tools • By clicking “Configuration” in the FCS, you can choose to enable, disable, extend, and shorten time for the autonomous and teleoperated periods.

  22. Diagnostic Tools • By clicking “Details” next to your team’s robot, you can gain access to more information including the firmware version, and IP Address.

  23. Further Diagnostics • By clicking on your robot’s IP address in the “Details” menu, a window will pop up with even more information regarding amount of packets sent, and number of joystick messages.

  24. General Tips and Tricks • Don’t forget no numbers or other characters in the SSID • The SSID is case-sensitive in the Samantha Configuration Utility • Use a flash drive ≥2GB to configure your Samantha • Having an indicator light on your flash drive is useful to confirm your module is reading the configuration • If you switch networks on your computer, the FCS needs to be restarted • Position your robotics router close to the field for a good connection • Use Anderson Powerpole connectors to ensure the Samantha Module receives uninterrupted power • Use zip ties to hold down any excess USB cable so it cannot shake if the robot takes a hit • Don’t mount the Samantha module on metal backing, as radio signals are affected • Because the antenna are parallel with the long edge, mount it with the narrow, flat side parallel to the ground • Make your power switch easily accessible. If the NXT freezes, the motors with continue moving until the main power switch is shut off • The red button and lights on the Samantha must be easily accessible
