A low cost motion capture system for improving the reality of humanoid robot simulator by machine learning
Abstract
Simulation is very important tool in the development of robot system. However it is really difficult to build a simulator which behaviors close to real robot, especially in the domain of humanoid robot motion, e.g. biped walking. This is because there are a lot of parameters in simulator needs to be adjusted according to real system, and some mechanisms are difficult to be modeled explicitly. Machine learning algorithms can be used to optimize parameters or learning implicit models, but it needs a lot of training data. Traditional motion capture system are expensive and limited for this. In this paper, we use a low cost RGB-D sensor (e.g. kinect) to collect motion data of humanoid robot NAO, and use them as training data of machine learning for improving the reality of RoboCup official simulator -- SimSpark.
