Is there any way we can get the final release of version 3.2 to be able to receive twist msg instruction from mavros/mavlink. Currently it is not handled properly.
At the moment, ardurover ignores any Twist or TwistStamped message published over ROS topics.
We implemented a workaround. If the incoming mavlink message has zero yaw rate and non-zero velocity, interpret it as setting velocity. Otherwise, if it has zero velocity and non-zero yaw rate, interpret as yaw rate. Set the ignore flags accordingly. But this won't work if we are trying to set a non-zero yawrate and a non zero throtthle at the same time. Which is crucial for course correction.
more details can be found in my post here - mavlink msg ignored
Also, I need some clarification on what you mean by pivot turn. Is this the same as a spot turn?
See the two videos in this link
robot turning - modes
Is pivot turn the equivalent of a swing turn as shown in the link I posted above?
