Test Rangefinders for detecting cylindrical obstacles in IARC arena

[aditya2592]

@gauravgardi What is the plan for cylindrical object detection? Till the parent classes and other infrastructure is ready we can prototype the hardware we would be using

[gauravgardi]

I think we can use sharp sensors for it. But before proceeding with that I'll test the sensors once to see what is the quality of data we get with it. I'll report about the results by next Sunday, 22nd Jan,2017.

@gauravgardi Any update on this?

[gauravgardi]

I didn't get the time to test it yet. I'll surely report by 1st Feb

• override of signal by arduino working.
• sharp has a very a small range of operation, but it can work fine if we make a skirt on the quadcopter.
• needs PID tuning and real time flight test.

Video/PR/Code Link?

[gauravgardi]

@sam17 code is updated in the repo. @amanchandra333 update the wiki with the documentation for this code. Also put the problems which were faced during the test and also the possible solutions we discussed. And from now on post the problems here first and then we should discuss it rather than doing it the other way around.

@amanchandra333 update the wiki please.

Sharp sensors aren't working fine. With an effective range of 50 cm, the sharp can't detect obstacles in more than 15 degrees angle in horizontal and 12 degrees in vertical. Even with 8 sharps, we'll encounter big blind spots. So, I don't think a skirt of sharp will do our task.

Interesting. More sharps maybe? Or what other things are you people thinking? Rotating sonar?
