ASORO, A*STAR Social Robotics, has developed a interactive mobile platform called Rio. The entire base was developed from scratch and it runs on the ROS platform. The user is able to use speech recognition to command the robot remotely. There are many other abilities that are not featured.
The aim of the project is to develop a low cost general mobile base. It is compatible with ROS and that enables developer to use this platform together with manipulators and other hardware that is compatible to perform much more.
One of the projects they are working on is using the Microsoft Kinect for human detection and tracking.
