Problem with Distance Measurement

[lorin.unger]

I’m working with the SensorWalkSkill starting from the tutorial chapter.

Everything seems to work fine except the Hexa doesn’t register the distance.

The tutorial has you output the registered distance and it never changes from the 1500mm it defaults to whether I put my hand in front of it or it walks into something.

On the chance it was a data entry error on my part I also tried running the fully written SensorWalkSkill example skill with the same result.

I also tried outputting the error messages from distance.Start() and distance.Value() but they were empty.

Any guidance on how to troubleshoot from a code perspective or to confirm there isn’t a hardware issue is appreciated!

It seems like you are doing all the right checks. The distance.Start() and distance.Value() should definitely have some values that are outputted.

As a test, can you install the “AutoCruiseGuard” skill fro the HEXA store? If the HEXA isn’t avoiding any obstacles, then we may have to test the hardware.

Thanks for the response.

To be clear, distance.Value() wasn’t returning anything as an error. distance.Value() does return 1500 as a distance reliably but it doesn’t decrease/change even when the sensor is blocked.

I’ll install and run the AutoCruiseGuard skill and post the result.

Installed AutoCruiseGuard - yep, it just walks into things…

Definitely seems like a hardware issue. We’ll find a new replacement sensor for you.
