Interesting video by Boston Dynamics about robots helping each other to open a door. Maybe next time it will be about robots fighting against each other. Think about two armies at war against each other, with each soldier (a robot) collaborating with his team to fight the enemy (consisting of robots as well.) You could make a movie out of it!
A more peaceful example of applications is driver-less cars. These cars could cooperate together to optimize everyone's commute, unlike human drivers focused on optimizing their own commute at the expense of other drivers. Yet each driver-less car would probably be powered by a different algorithm, allowing some of these robots to be more aggressive drivers than others.
