class pydrake.common.schema.Rotation

A specification for an SO(3) rotation, to be used for serialization purposes, e.g., to define stochastic scenarios. This structure specifies either one specific rotation or else a distribution of possible rotations. It does not provide mathematical operators to compose or mutate rotations. Instead, users should call either GetDeterministicValue() or ToSymbolic() to obtain a RotationMatrix value that can be operated on.

For an overview of configuring stochastic transforms, see schema_transform and schema_stochastic.

See implementing_serialize “Implementing Serialize” for implementation details, especially the unusually public member fields.

class pydrake.common.schema.Transform

A specification for a 3d rotation and translation, optionally with respect to a base frame.

For an overview of configuring stochastic transforms, see schema_transform and schema_stochastic.

See implementing_serialize “Implementing Serialize” for implementation details, especially the unusually public member fields.

__init__(*args, **kwargs)

Overloaded function.

  1. __init__(self: pydrake.common.schema.Transform) -> None

Constructs the Identity transform.

  1. __init__(self: pydrake.common.schema.Transform, other: pydrake.common.schema.Transform) -> None

  2. __init__(self: pydrake.common.schema.Transform, arg0: pydrake.math.RigidTransform) -> None

Constructs the given transform.

property base_frame
GetDeterministicValue(self: pydrake.common.schema.Transform) → pydrake.math.RigidTransform

If this is deterministic, retrieves its value.

Raises

RuntimeError if this is not fully deterministic. –

IsDeterministic(self: pydrake.common.schema.Transform) → bool

Returns true iff this is fully deterministic.

Mean(self: pydrake.common.schema.Transform) → pydrake.math.RigidTransform

Returns the mean of this rotation. If this is deterministic, the result is the same as GetDeterministicValue. If this is random, note that the mean here is simply defined as setting all of the random variables individually to their mean. Various other measures of the resulting RigidTransform (e.g., the distribution of one of the Euler angles) may not necessarily match that measure on the returned value.

property rotation

A variant that allows for several ways to specify a rotation.

Sample(self: pydrake.common.schema.Transform, generator: pydrake.common.RandomGenerator) → pydrake.math.RigidTransform

Samples this Transform. If this is deterministic, the result is the same as GetDeterministicValue.

set_rotation_rpy_deg(self: pydrake.common.schema.Transform, rpy_deg: numpy.ndarray[numpy.float64[3, 1]]) → None

Sets the rotation field to the given deterministic RPY, in degrees.

ToSymbolic(self: pydrake.common.schema.Transform) → pydrake.math.RigidTransform_[Expression]

Returns the symbolic form of this rotation. If this is deterministic, the result will contain no variables. If this is random, the result will contain one or more random variables, based on the distributions in use.
