Re: [OpenRAVE-users] regarding the physics engine

[Jong E. K. <jon...@an...>]

Hello rosen,
To use the build-in function,SetJointTorques(torque,False), I need to use
the openravepy interface, which is the pythons. Since I am not familiar
with pythons language, there is any way that I can use octave (matlab)?
because I am familiar with matlab.

In addition, How can I update? I am using the unix, Ubuntu. Do I need to
download the file again and install it?  On the website, it only tells how
to update in the window version.

thanks.
