Ants are tiny, amazing insects. There are many things we do not know about them. Scientists just found how ants get from A to B, without getting lost. They can go in a straight line, whatever direction they are facing. The BBC said it is the same as, "trying to find your way home while walking backwards or even spinning round". Ants use the Sun, their memories, and what they can see around them. A professor said ants are like self-driving cars.
The scientists studied ants in Spain. Their report is in the journal 'Current Biology'. They said ants could travel far from their nest even when things are in their way or if they have to drag heavy food. The professor said: "Ants have a…tiny brain…yet they can [move] successfully under many difficult conditions, including going backwards." She said understanding ants will help us to build new robot systems that copy the ant's behaviour.
