Multi Ranger Deck with Thermal Camera

Over past few weeks I was working on developing a new ToF sensor deck which can be used for SLAM purposes and for obstacle avoidance. The deck has space for 13 ToF sensors to cover a maximum area of the 3D space. A 16bit IO expander has been used to drive all sensors separately. In addition to that ...

Other variables which are in the log group print corresponding values in the terminal. However there is no error showing in the CF console and set_hoverpoint command is...

Log multiple variables using python client

When I try to add additional log variables to BasiclogSync.py file, it gives an error when there are more than 9 variables. Is there a way to get the log data from more than 10 variables using python client?

CF doesn't work after forcing deck drivers

Corrupted OW memory message appears in the console when I plug one of my decks. After forcing the driver by adding it to the config.mk and using Make Debug to compile, it didn't boot properly. By adding DEBUG=1 in config.mk the deck started to work but there were some issues. When I give set_hoverpo...

Re: Integrate Magnetometer with Kalman Estimator

Does the algorithm use magnetometer readings if we pass values from an external magnetometer ?

Integrate Magnetometer with Kalman Estimator

After observing the log data of the magnetometer a considerable noise is noticed. When I rotate the CF and come back to the previous heading, it gives different headings in each time. Because of that I have following questions. 1) Does kalman estimator use the onboard magnetometer readings ? 2) Will...

Fly higher than 2m using Flowdeck

Is there a way to bypass the height value in the following command and use the altitude calculated by the pressure sensor to hover in higher altitudes while using other parameters (Vx, Vy, yaw rate).

cf.commander.send_hover_setpoint(Vx, Vy, yaw, Height)
