settling_time()

def rosbag_tools.analyze_bag.settling_time	(		set_point,
			input_series,
			bounding_radius,
			min_time
	)

Calculate the settling time of input_series to be bounded for min_time.

Args:
    set_point: XYZWithTime of the reference point
    input_series (list): XYZWithTime of the points that should be evaluated
    bounding_radius: Float of the radius of the bounding sphere
    min_time: Float of the time, the input_series has to stay within bounds

Returns:
    settling_time: Float of the time for input_series to be settled

Definition at line 661 of file analyze_bag.py.

    work_constant: Float of the (rotor_constant * moment_constant) constant

Returns:
    total_work: Float of the work done in input_series

Definition at line 695 of file analyze_bag.py.

xyz_rms_error()

def rosbag_tools.analyze_bag.xyz_rms_error	(		set_point,

	)

Calculate the RMS error between a set_point and the points in input_series.

Args:
    set_point: XYZWithTime of the reference point
    input_series (list): XYZWithTime of the points that should be evaluated

Returns:
    rms: Float of the RMS Error of the XYZWithTime input_series
