I wanna know ...
dronecore::Offboard::VelocityBodyYawspeed Struct Reference
Type for velocity commands in body coordinates (forward, right, down and yaw angular rate).
float forward_m_s -
float right_m_s -
float down_m_s -
float yawspeed_deg_s -
what does *float down_m_s actually mean?
Is it the parameter to increase/decrease the current velocity?
Is it the parameter to move towards up/down?
plz try to answer as soon as possible...
