Overview

The visual-tracking-control project is a suite of cross-platform applications for visual tracking and visual servoing for the humanoid robot platform iCub.

The suite includes:

• hand-tracking: a visual end-effector tracker using a 3D model-aided particle filter [1];
• visual-servoing: a visual servoing YARP plugin to control the pose (position and orientation) of the end-effector using image feedback [2].
  • The visual-servoing consist of two plugins, a client and server version. On one hand, the server must be always running via yarpdev and is responsible to command the robot. On the other hand, the client is dynamically loaded by any application using visual servoing interfaces and has the sole purpose of communicating commands to the server. This architecture enable distributed computation over different machine and decouples client and server implementations.

The output of the hand-tracking application can be visualized by means of the iCubProprioception module. iCubProprioception provides an augmented-reality application which superimposes the 3D model of the end-effector onto the camera images, using the estimated pose provided by hand-tracking.
