Destination¶
Instruct the robot to move towards a given target
This actuator reads the coordinates of a destination point, and moves the robot in a straight line towards the given point, without turning. It provides a very simplistic movement, and can be used for testing or for robots with holonomic movement. The speeds provided are internally adjusted to the Blender time measure.
Configuration parameters for Destination¶
You can set these properties in your scripts with <component>.properties(<property1>=..., <property2>=...)
.
Tolerance
(default:0.5
)- (no documentation available yet)
Speed
(default:5.0
)- (no documentation available yet)
ControlType
(string, default:"Velocity"
)- Kind of control, can be one of [‘Velocity’, ‘Position’]
RemainAtDestination
(bool, default:False
)- If true (default: false), the robot actively attempts to remain at the destination once reached. This is especially useful for flying robots that would otherwise typically fall.
Data fields¶
This actuator reads these datafields at each simulation step:
x
(float, initial value:current X pos
)- X coordinate of the destination
y
(float, initial value:current Y pos
)- Y coordinate of the destination
z
(float, initial value:current Z pos
)- Z coordinate of the destination
Interface support:
ros
as geometry_msgs/Point (morse.middleware.ros.destination.PointReader
)socket
as straight JSON deserialization (morse.middleware.socket_datastream.SocketReader
)yarp
as YarpReader (morse.middleware.yarp_datastream.YarpReader
)
Services for Destination¶
get_configurations()
(blocking)Returns the configurations of a component (parsed from the properties).
Return value
a dictionary of the current component’s configurations
get_properties()
(blocking)Returns the properties of a component.
Return value
a dictionary of the current component’s properties
set_property(prop_name, prop_val)
(blocking)Modify one property on a component
Parameters
prop_name
: the name of the property to modify (as shown the documentation)prop_val
: the new value of the property. Note that there is no checking about the type of the value so be careful
Return value
nothing
Examples¶
The following examples show how to use this component in a Builder script:
from morse.builder import *
# adds a default robot (the MORSE mascott!)
robot = Morsy()
# creates a new instance of the actuator
destination = Destination()
# place your component at the correct location
destination.translate(<x>, <y>, <z>)
destination.rotate(<rx>, <ry>, <rz>)
robot.append(destination)
# define one or several communication interface, like 'socket'
destination.add_interface(<interface>)
env = Environment('empty')
