obstacle detection

360 degree proximity sensing?

Dear: LMR

Hello guys this is me Noah again and I was wondering how you would make a mount that can hold a bunch of proximity sensors most likely going to be ping sensors in a circle so that I can detect obstacles 360 degrees. Unfortunately I couldn't find any such mount or sensor that was cheap online so I am assuming you guys would know more than I would. There has to be a way to line up a bunch of proximity sensors in 360 degrees. Can I have some help? Thank you guys so much!!!
