ロボットワークベンチはKukaのような産業用6軸ロボットのシミュレートのためのツールです。 以下の作業を行うことができます:

  • ロボット、加工物とシミュレーション環境のセットアップ
  • 軌道の作成と書き込み
  • CAD部品形状を軌道に分解
  • ロボットの動作と到達可能範囲のシミュレート
  • ロボットプログラムファイルへの軌道のエクスポート

Trajectories

Tools to create and manipulate trajectories. There are two kinds, the parametric and non parametric ones.

non parametric trajectories

parametric trajectories

Scripting

This section is generated out of: https://github.com/FreeCAD/FreeCAD_sf_master/blob/master/src/Mod/Robot/RobotExample.py You can use this file directly if you want.

Example how to use the basic robot class Robot6Axis which represents a 6-axis industrial robot. The Robot module is dependent on Part but not on other modules. It works mostly with the basic types Placement, Vector and Matrix. So we need only:

from Robot import *
from Part import *
from FreeCAD import *

Basic robot stuff

create the robot. If you do not specify another kinematic it becomes a Puma 560

rob = Robot6Axis()
print rob

accessing the axis and the Tcp. Axes go from 1-6 and are in degree:

Start = rob.Tcp
print Start
print rob.Axis1

move the first axis of the robot:

rob.Axis1 = 5.0

the Tcp has changed (forward kinematic)

print rob.Tcp

move the robot back to start position (reverse kinematic):

rob.Tcp = Start
print rob.Axis1

the same with axis 2:

rob.Axis2 = 5.0
print rob.Tcp
rob.Tcp = Start
print rob.Axis2

Waypoints:

w = Waypoint(Placement(),name="Pt",type="LIN")
print w.Name,w.Type,w.Pos,w.Cont,w.Velocity,w.Base,w.Tool

generate more. The trajectory always finds automatically a unique name for the waypoints

l = [w]
for i in range(5):
  l.append(Waypoint(Placement(Vector(0,0,i*100),Vector(1,0,0),0),"LIN","Pt"))

create a trajectory

t = Trajectory(l)
print t
for i in range(7):
  t.insertWaypoints(Waypoint(Placement(Vector(0,0,i*100+500),Vector(1,0,0),0),"LIN","Pt"))

see a list of all waypoints:

print t.Waypoints
 
del rob,Start,t,l,w

Working with the document objects

Working with the robot document objects: first create a robot in the active document

if(App.activeDocument() == None):App.newDocument()
 
App.activeDocument().addObject("Robot::RobotObject","Robot")

Define the visual representation and the kinematic definition (see Robot 6-Axis and VRML Preparation for Robot Simulation for details about that)

App.activeDocument().Robot.RobotVrmlFile = App.getResourceDir()+"Mod/Robot/Lib/Kuka/kr500_1.wrl"
App.activeDocument().Robot.RobotKinematicFile = App.getResourceDir()+"Mod/Robot/Lib/Kuka/kr500_1.csv"

start positon of the Axis (only that which differ from 0)

App.activeDocument().Robot.Axis2 = -90
App.activeDocument().Robot.Axis3 = 90

retrieve the Tcp position

pos = FreeCAD.getDocument("Unnamed").getObject("Robot").Tcp

move the robot

pos.move(App.Vector(-10,0,0))
FreeCAD.getDocument("Unnamed").getObject("Robot").Tcp = pos

create an empty Trajectory object in the active document

App.activeDocument().addObject("Robot::TrajectoryObject","Trajectory")

get the Trajectory

t = App.activeDocument().Trajectory.Trajectory

add the actual TCP position of the robot to the trajectory

StartTcp = App.activeDocument().Robot.Tcp
t.insertWaypoints(StartTcp)
App.activeDocument().Trajectory.Trajectory = t
print App.activeDocument().Trajectory.Trajectory

insert some more Waypoints and the start point at the end again:

for i in range(7):
  t.insertWaypoints(Waypoint(Placement(Vector(0,1000,i*100+500),Vector(1,0,0),i),"LIN","Pt"))

t.insertWaypoints(StartTcp) # end point of the trajectory
App.activeDocument().Trajectory.Trajectory = t
print App.activeDocument().Trajectory.Trajectory

Simulation

To be done.....

Exporting the trajectory

The trajectory is exported by Python. That means for every control cabinet type there is a post-processor Python module. Here is in detail the Kuka post-processor described

from KukaExporter import ExportCompactSub

ExportCompactSub(App.activeDocument().Robot,App.activeDocument().Trajectory,'D:/Temp/TestOut.src')

and that's kind of how it's done:

for w in App.activeDocument().Trajectory.Trajectory.Waypoints:
	(A,B,C) = (w.Pos.Rotation.toEuler())
	print ("LIN {X %.3f,Y %.3f,Z %.3f,A %.3f,B %.3f,C %.3f} ; %s"%(w.Pos.Base.x,w.Pos.Base.y,w.Pos.Base.z,A,B,C,w.Name))
