A few things changed from hydro to indigo.



ChangeLog

The navigation underwent a major overhaul. This is probably the first time it's had a serious tuning since the turtlebot software first came out. We certainly never got around to it for hydro and so it was mostly running off defaults or initialisations from Turtlebot 1. See this blog post for more details.

Interactions & Remocons

Indigo introduces new ways to interact with your turtlebot via qt and android remocons.

You can find a quick guide to get started with the qt remocons in Interacting with your Turtlebot and some tutorials about developing your own robot applications and interactions in Create your First Rapp and Create your First Interaction.

Help on using the android remocon can be found in Android Interactions and tutorials for developing android applications for the remocon is in the android corner.

3D Sensor

The default 3D sensor is now Asus Xtion Pro.

Due to EOL of Microsoft Kinect, the default 3D sensor is now configured as Asus Xtion Pro. If you have used a Kinect for your TurtleBot, please refer Kinect Setup for kinect configuration.

Supporting two locations for Asus Xtion Pro

Indigo supports two locations for Asus Xtion Pro(asus_xtion_pro and asus_xtion_pro_offset). asus_xtion_pro is a default configuration which locates the sensor at the center. asus_xtion_pro_offset is old asus xtion pro location which is slightly located on the right. It is to keep backward compatibility for previous distributions TurtleBot(hydro, groovy) that asus xtion pro are mounted. See this pull request for more details. These are configurable via TURTLEBOT_3D_SENSOR environment variable.

Freenect as Kinect Driver

While investigating kinect incompatibility issue for trusty, we found out that openni driver stop supporting Kinect. So we switched to use freenect_camera for Kinect. See this issue for more details.

Environment Variables

Indigo TurtleBot utilises environment variables to configure your TurtleBot settings. It allows you to configure your robot without modifying minimal.launch. See TurtleBot Environment Variables for more details.

Stage

TurtleBot is now in stage simulation. stage is a 2D simulation tool which allows to experiment navigation stack quick and easy. See TurtleBot Stage Tutorial to learn how to run TurtleBot in stage.

Also note that TurtleBot Gazebo 3D Simulation is still available.

Multi-Turtlebot Implementation

TurtleBot is now supported by multi-master system using Concert framework. See Turtlebot Concert package to setup concert(multi-master system) in your environment to teleoperate multiple turtlebots.
