urx is a python library to control a robot from 'Universal robot'. urx is a python library to control a robot from 'Universal robot'.
Internally, to control the robots, urx uses both the 'secondary port' interface and the real-time/matlab interface. Both the 'secondary port' interface and the real-time/matlab interface of the UR controller are used.
urx can optionally use the python-math3d https://launchpad.net/pymath3d library to receive and send transformation matrices to the robot urx can optionally use the python-math3d https://launchpad.net/pymath3d library to receive and send transformation matrices to the robot
