It is a miniature-size version of the ultra-reliable PX4 Storm, a double/single-action pistol that keeps gaining an enthusiastic following among military and police organizations worldwide. Both software AND hardware are open source. You can set the weights using the parameters CBRK_NO_VISION to 0 Motion capture system¶ OptiTrack motion capture system (Mocap hereinafter) works as follows. Once the configuration is changed to 'Rover' mode (even after calibrating the sensors and the battery), it doesn't work. If the system is following the MAVLink standard, the system state is mainly defined by three orthogonal states/modes: The system mode, which is either LOCKED (motors shut down and locked), MANUAL (system under RC control), GUIDED (system with autonomous position control, Further I want to send position data (ATT_POS_MOCAP) to pixhawk.
