README libroboint/Robo Explorer ROS Connector
==========
This contains a ROS package to control the fischertechnik Robo Explorer with ROS using libroboint.
Its is split in the following Nodes:
-libft_adapter: Accesses the Interface over libroboint.
 Inputs are send via ft/get_inputs message.
 Outputs are set with ft/set_output and ft/set_motor message.
-robo_explorer_hardware: Hardware functions for the ros_control DiffDriveController
-robo_explorer.py: Provides additional Robo Explorer functions, e.g. sensors

The world frame of the navigation setup is "odom" since this robot is running without SLAM and amcl.

Hardware setup:
<---------->
You need to use the Robo Explorer with wheels instead of tracks because the tracks are too inaccurate for Odometry.
I used the two wheel Setup from Mobile Robots 2.


Requirements:
<---------->
ROS - http://www.ros.org tested under Groovy, Indigo, Kinetic
libroboint - http://defiant.homedns.org/~erik/ft/libft/
