user29846: I am new to this, and my kid got an Elegoo smart robot car kit v2.0 for Christmas. We assembled the car, but after downloading the software, the program always states:

Arduino: 1.6.13 (Windows Store 1.6.13.0) (Windows 10), Board: "Arduino/Genuino Uno"
Sketch uses 2,242 bytes (6%) of program storage space. Maximum is 32,256 bytes.
Global variables use 210 bytes (10%) of dynamic memory, leaving 1,838 bytes for local variables. Maximum is 2,048 bytes.
  avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.
Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
  "Show verbose output during compilation"
  option enabled in File -> Preferences.

I don't know what other information is important. Can somebody please help me?
Thank you.

user10394: When the port is greyed out its not available (I know you had worked that out) so you have a problem with you serial to USB drivers.
Looking at the kit I think you are connecting the UNO to a USB port on your PC/laptop using a blue cable.
 1. Please can you check that the cable is connected properly.
 2. Can you try a different USB port on the PC (don't use a USB hub - some don't work).
 3. Does Windows recognise a device has been plugged?
 4. Are you running it as administrator, you will need to be to install the drivers.
 5. Can you try connecting it to a different PC?
If these don't fix it then, please comment and well go through looking at the device manager.
Hope it works, it looks like fun.
