GetActiveManipualtor -> GetArmIndices

[rod_a]

Hi everybody,

I've wrote the trajectory example with my robot, but appears this message:

responsable@responsable-VirtualBox:~/Desktop/maq$ python maq.py
Traceback (most recent call last):
  File "maq.py", line 23, in <module>
    traj = manipprob.MoveManipulator(goal,outputtrajobj=True,execute=False)
  File "/usr/local/lib/python2.7/dist-packages/openravepy/_openravepy_/interfaces/BaseManipulation.py", line 109, in MoveManipulator
    assert(len(goal) == len(self.robot.GetActiveManipulator().GetArmIndices()))
AttributeError: 'NoneType' object has no attribute 'GetArmIndices'

any idea about the problem?

The code is:
manipprob = interfaces.BaseManipulation(robot)
goal=[-0.75,1.24,-0.064,2.33,-1.16,0.0]
traj = manipprob.MoveManipulator(goal,outputtrajobj=True,execute=False)
spec = traj.GetConfigurationSpecification()

My robot is a KUKA robot, with 6 joints


Thanks very much

Hi,

Does your robot xml have manipulator defined ?

http://openrave.programmingvision.com/wiki/index.php/Format:XML#Defining_Manipulators

You can set the active manipulator using robot.SetActiveManipulator(manipulator name)

Hope it works once you do this.

Regards
