This short talks reviews recent results in extending the stochastic dynamics of Brownian particles towards an agent-based model of biological motion. Brownian agents denote a particular class of driven particles with the ability to take-up energy from the environment, to store it in an internal depot and to use it for different actions. E.g., this energy may be used for active, self-propelled motion and for collective interaction with other agents, such as swarming. The energetic conditions for active motion are discussed and different types of local and global couplings between the agents are investigated. Further a possible application to the swarming behavior of Daphnia is discussed.
