Hans: Rotates around and/or backwards without obstacles

As soon as Hans is lifted, the bot's sensors may come loose, causing Hans to exhibit strange behavior. Such as spinning in circles, driving backward without an obstacle.

It is important that the bot's sensors are properly clicked into place on Hans. Hans has 4 bot sensors, 2 at the back and 2 at the front. In this video, you can see how to click the bot's sensors into place.
