Abstract

We discuss about the modeling technology in the object manipulation of the robot arm that is equipped with flexible finger joints. In recent years, flexible robot fingers are getting attention because of their handling capability and safety. However, the position and contact force of manipulated object take much non-linear uncertainty from the flexibility. In this paper, we propose the modeling framework of the position and contact force of the manipulated object. The proposed framework is an online learning method that is composed of motor babbling, dynamics learning tree (DLT), and \(\epsilon \)-greedy method. In the experiments, the effectiveness of DLT was compared with neural network (NN), the effectiveness of the proposed framework was validated using a drawing task of a humanoid robot that equipped with flexible finger joints. The proposed framework was able to realize a fully automated incremental-manipulation-learning.

The same algorithm is used in another proposition [17] that is presented in this conference.

The humanoid robot NAO was placed on the top of the figures. It moved a pen using its right hand. The result of Exploitation mode has a bias compared with the others. This might be because Exploitation mode searches pen tip positions conservatively by exploiting the knowledge of DLT.
