Can't generate transform6d for Kinova's Jaco #378

Open mlauret opened 8 years ago

mlauret commented 8 years ago

Hello ! I am stuck on a problem for quite some time : I try to generate a ikfast .cpp for Kinova's Jaco V2 with 6 DOF. I'm using the latest version of Openrave (branch Master) 0.9 on a Ubuntu 14.04 32Bits with 4GB of RAM. I didn't succeed with the 2 attempt described below, I think it's a problem with the Jaco2 special kinematics but i'm not sure. Maybe you can understand if it's a bug from openrave or from me.

The .dae file i'm using is the one I created from the Kinova's Github : https://github.com/Kinovarobotics/kinova-ros/blob/master/jaco_model/urdf/standalone_arm.xacro

I used urdf_to_collada to generate the .dae, then I rounded it to 3 digits : https://drive.google.com/file/d/0B0BRMr7Z9cxfR1FDcDdRbjJua1U

Everything seem fine with openrave-robot.py jaco_arm.rounded3.dae --info links :

jaco_link_finger_1 8 jaco_link_hand
jaco_link_finger_2 9 jaco_link_hand
jaco_link_finger_3 10 jaco_link_hand

Then I launch : 

~/catkin_ws/src/kinova-ros$ python `openrave-config --python-dir`/openravepy/_openravepy_/ikfast.py --robot=jaco_arm.rounded3.dae --iktype=transform6d --baselink=1 --eelink=7 --savefile=jaco_arm.cpp

The generation don't work, it compute for ~40min and when openrave ate all my RAM, it crash. The full log can be found here : http://justpaste.it/jacoikfastcrash (I don't know what's important or not, so I pasted everything... brave yourself, big equation are coming).

The log begin by :

So, I tried with another urdf from https://github.com/iki-wgt/jaco-ros/blob/master/kinova_description/urdf/standalone_jaco2.xacro :

but the result is pretty much the same :
