Current activities are focussed on the preparation of the selected MAV (Skybotix FlyboX^TM) for the REMAV experiment. A new instance of the VSS optical-flow based speed and position sensor suited for REMAV is in the specification phase and is planned to be available this summer. FlyboX^TM  is being complemented with a (reference) position sensor based on a modified commercial mouse sensor. The requirements and specifications for the experiment practical setup are in definition.
