Image processing used in our work

by admin on March 8, 2012 · 102 Comments

A lot of information which is used in our reach or grasp models is visual. Or, can be extracted from visual information (like distance, position, size, orientation, etc.). In the last weeks, we add image processing module built upon OpenCV library to our project and we use several OpenCV functions to process iCub’s camera image [...]

Additional information from the iCub Simulator

by admin on November 16, 2011 · 100 Comments

In our work, we study how methods of machine learning could be used to let iCub learn to reach and grasp objects. Simulator offers various propriocentric information about its state. Hovewer, we could get only the position of the center of iCub’s hand and that is not enough to calculate hand orientation in the space [...]

iCub learns how to grasp objects

Today I implemented simple algorithm to lift object when iCub successfully grasps it. While iCub was learning (online learning of Grasping CACLA), I took this very nice screenshot of sucessful grasp and lift of the grasped object. Video – iCub learns grasping (after 200-300 learning epizodes)

iCub simulator objects weight

by admin on October 19, 2011 · 93 Comments

iCub simulator is built on Open Dynamics Engine (ODE) and OpenGL. We found out, that in the simulator, all objects have very small weight and we cannot set the weight or density of the objects. While in our work we expect iCub to grasp objects with different weights, we need to overcome this problem. Since [...]

Reaching & Grasping experiments with iCub

by admin on October 19, 2011 · 88 Comments

In the last two months I did several experiments on my iCub simulator. Reaching I had enhanced my reaching module and tested it with various parameters and state/action representations. In each experiment I train reaching CACLA for 1000-2000 episodes and test it on the fly after every 50 episodes. In most of experiments I used [...]
