Discovered that we crash when we press multiple times loadfromDB button in GUI. It also doesn't work properly

Added support for Address. Need to do it in a better way, now it is in a simple way, need to write the whole address

added support for saving data in the database. Added cf zone index to database. Now need to fix all exceptions

solved issued on data record. extended Student.launch with rqt dashboard plugin to send manually configured topics.

Crazyradio logs batterz status and writes to bag file. Conversion issue and bagdata is useless. But battery status and stabilizer logs are already printed to console at 1000ms rate

only some small additions for data recording. safecontroller is also writing to bagfile allowing to find the controller mistake.

changed the function convertIntoBodyFrame(request, est, state, yaw_measured) such that it uses the measured yaw without considering the setpoint - eliminates the drifting problem but is probably still wrong regarding the controlling logic. Added an rqt-plot to the launch file.

supposedly fixed problem caused when multiple Cf-Objects are selected in Vicon. Plus some cosmetic changes

implemented Kalman filter as state estimator, but position is converging very slowly and causes oscillations in x, y and z direction
