It has been renamed to "Arduino Uno". The "Genuino" brand name has been abandoned by Arduino. It was created as a worst case scenario fallback during a time of legal dispute over ownership of the "Arduino" trademark.

Try this:
- Unplug your robot from the computer.
- Select Tools > Port from the Arduino IDE's menus.
- Note the ports, if any, listed in the menu.
- Close the Tools menu.
The ports list is only updated when the Tools menu is re-opened, so this step is essential. - Plug your robot into the computer.
- Select Tools > Port from the Arduino IDE's menus. - The new port listed in the menu is the port of the robot.
