Today we tested a few new extensions for MISSy at the Mönkeberger beach. First of all, MISSy geta a new gearing unit. Our first attemts with a rudder in front of the screw were not very sucessful. The new way of controlling MISSy is much better. However, after a few minutes we had some material problems. One further iteration is necessary here. Furthermore, we tested the GPS unit - everything works as expected. Also our new equipment boxes did a good job - next time we will fill them with equipment.
