We are trying to install the createautonomy driver for our Irobot Create 1. We followed the steps outlined here: https://github.com/AutonomyLab/createautonomy, but got an error when we enter roslaunch ca_driver create_1.launch. Here is the message we get:

Any idea of what we're doing wrong? We are using Ubuntu 14.04 and ROS Indigo. Thanks for the help
