ToolModel

class compas.robots.ToolModel(visual, frame_in_tool0_frame, collision=None, name='attached_tool', link_name=None)[source]

Bases: RobotModel

Represents a tool to be attached to the robot’s flange.

Attributes

visual (Mesh) – The visual mesh of the tool.
frame (Frame) – The frame of the tool in tool0 frame.
collision (Mesh) – The collision mesh representation of the tool.
name (str) – The name of the ToolModel. Defaults to ‘attached_tool’.
link_name (str) – The name of the Link to which the tool is attached. Defaults to None.

Examples

>>> import compas
>>> from compas.datastructures import Mesh
>>> from compas.geometry import Frame
>>> mesh = Mesh.from_stl(compas.get('cone.stl'))
>>> frame = Frame([0.14, 0, 0], [0, 1, 0], [0, 0, 1])
>>> tool = ToolModel(mesh, frame)
