What's Coming Up: Web Interface
One of the ROS libraries currently under development is a web infrastructure that allows you to control the robot and various applications via a normal web browser. The web browser is a powerful interface for robotics because it is ubiquitous, especially with the availability of fully-featured web browsers on smart phones.
With just a couple of clicks from any web browser, you can start up and calibrate a robot. We've written applications for basic capabilities like joystick control and tucking the arms of the PR2. We've also written more advanced applications that let you select the locations of outlets on a map, and instruct the PR2 where to plug in. We hope to see many more applications available through this interface so that users can control their robot easily with any web-connected device.
We're also developing 3D visualization capabilities based on the O3D extension that is available with upcoming versions of Firefox and Chrome. This 3D visualization environment is already being tested as a user interface for grasping objects.
All of these capabilities are still under active development and not recommended for use yet, but we hope that they will become useful platform capabilities in future releases.
