Point

Metres. Arithmetic returns Point, as the ROS type has no separate displacement type.

Import

from robot_msgs.geometry import Point

ROS 2geometry_msgs/msg/Point

Fields

Name	Type	Default
`x`	`float`	`0.0`
`y`	`float`	`0.0`
`z`	`float`	`0.0`

Example

One instance from the package's own test catalog; the output is its real repr().

Point(x=0.1, y=0.2, z=0.3)

to_dict() as JSON

{
  "_type": "geometry/Point",
  "x": 0.1,
  "y": 0.2,
  "z": 0.3
}

Long arrays are cut after 16 values and say so with “…”.

`replace`

from Msg

replace(**changes: Any) -> M

`to_dict`

from Msg

to_dict() -> dict[str, Any]
