Ask HN: What's the best way to make a RC car drive around a permitter?
Assume I wanted to make a RC car drive within a perimeter.  Say a table.  What would be the best way to achieve this?<p>I see https:&#x2F;&#x2F;github.com&#x2F;ApolloAuto&#x2F;apollo exists which is an autonomous driving software.  But I feel that is over kill.<p>I was trying to imagine either using a sort of electric fence, like a dog collar, and maybe something more analog to be able to detect the perimeter and just have it know to stop or reverse with a quick servo.
