The current generation of drifters includes a propulsion system designed to provide capacity for collision avoidance and essential minor control tasks. In a static environment, the drifters can travel linearly at a speed of approximately 30 cm/second and rotate approximately 225 in one second. The following videos represent early tests of drifter motor authority given various initial forcings.
An early demonstration of control algorithms implemented on the drifter platform included autonomous waypoint tracking in the Hearst Memorial Pool at UC Berkeley...
The drifters are also designed with a capacity to dive below the surface--a feature to be implemented in the upcoming fleet expansion. This provides the drifters...
The drifters have undergone multiple field tests, including demonstrations in which drifter-generated flow velocity...
