Render Open Drifter

The “Open Drifter” (OD) is a small river drifter developed by the Centre for Biorobotics at Tallinn University of Technology and supported by GEA. The OD is an IoT device that can provide real-time estimates of position, travel speed, accelerations, orientations, or magnetic fields using mobile or radio communication at 1 Hz as well as onboard recording at 5-10 Hz. These properties make the drifter an ideal tool for the instantaneous characterization of small to large river streams. The OD is developed with low-cost open software and hardware which makes affordable the scalability of its production.
