RARotation

class RARotation

Rocky PrePost Scripting wrapper representing a Rotation motion.

Retrieve this specific wrapper after setting the correct motion type on a RAMotion. For example:

motions = motion_frame.GetMotions()
motion_1 = motions.New()
motion_1.SetType('Rotation')
rotation = motion_1.GetTypeObject()

Methods:

GetAngularAcceleration(unit: str | None = None)

Get the value of “Angular Acceleration”.

• Parameters: unit – The unit for the returned values. If no unit is provided, the returned values will be in “rad/s2”.

GetInitialAngularVelocity(unit: str | None = None)

Get the value of “Initial Angular Velocity”.

• Parameters: unit – The unit for the returned values. If no unit is provided, the returned values will be in “rad/s”.

SetAngularAcceleration(values: Sequence[str | float], unit: str | None = None)

Set the values of “Angular Acceleration”.

• Parameters:
  • values – The values to set. The values can be heterogeneous, the element of values can be an expression with input variables or a float. Must have exactly 3 elements.
  • unit – The unit for values. If no unit is provided, values is assumed to be in “rad/s2”.
• Raises: RockyApiError – If values doesn’t have exactly 3 elements.

SetInitialAngularVelocity(values: Sequence[str | float], unit: str | None = None)

Set the values of “Initial Angular Velocity”.

• Parameters:
  • values – The values to set. The values can be heterogeneous, the element of values can be an expression with input variables or a float. Must have exactly 3 elements.
  • unit – The unit for values. If no unit is provided, values is assumed to be in “rad/s”.
• Raises: RockyApiError – If values doesn’t have exactly 3 elements.
