Recently acquired a GoPiGo through an Educational workshop on the hardware. It came with an UltraSonic Sensor. However, I can not get it to work. I have tried the dist code, and even the example, but no matter where it is placed in relation to an object the returned value does not change. Could there need to be more programming, or perhaps I have a bad sensor. Thank for any help.
Can you send us a screenshot of the output that you are getting. Can you also send us a few pictures of the ultrasonic sensor connected to GoPiGo and code that you are using.
Along with these if you are using our Raspbian for Robots image, follow this guide, generate a test log and post it along with your reply.

I am using raspbian for robots. I am also haveing an issuse with the onboard wifi and bluetooth. Becuase of that Issue I am able to access the pi but not able to get it online after accessing it, and I was not able to get the Log.txt into for my pi desktop to the computer. I will try again if I am able to connect through ethernet.

Thanks a lot for sharing the log, just to confirm if the ultrasonic sensors are working, can you run this python program by commenting line 44 and uncommenting line 45. After running share with us the screenshot of the output. This code can be found in /home/pi/Desktop/GoPiGo/Software/Python/sensor_examples/ in your Pi.
