Dexterous manipulation is a challenging and important problem in robotics. While data-driven methods are promising approach, current benchmarks require simulation or extensive engineering support due to the sample inefficiency of popular methods. We present for TriFinger system, an open-source robotic platform dexterous focus 2020 Real Robot Challenge. The benchmarked methods, which were succes...

Model-free deep reinforcement learning has been shown to exhibit good performance in domains ranging from video games to simulated robotic manipulation and locomotion. However, model-free methods are known to perform poorly when the interaction time with the environment is limited, as is the case for most real-world robotic tasks. In this paper, we study how maximum entropy policies trained usi...

every discourse, written or oral, is the conveyer of some hidden agenda of the producer, most importantly in such genres of speech as journalism, politics, propaganda, and advertisements. given the role of translation in discourse, a difference exists between when the translator carries the ideological values of the elite in contrast with one with patriotic preferences. in this study a comparis...

Object manipulation techniques in robotics can be categorized in two major groups including manipulation with and without grasp. The aim of this paper is to develop an object manipulation method where in addition to being grasp-less, the manipulation task is done in a passive approach. In this method, linear and angular positions of the object are changed and its manipulation path is controlled...

Does short selling help or hinder disciplining managerial behavior? We examine managerial investment decision in a model with informed short-selling and short-term managerial incentives and show that short selling can cause firms to overinvest. The overinvestment problem is more severe for managers with stronger short-term incentives and for firms that lack quality investment opportunities. Emp...

The aim of this paper is to validate a virtual reality (VR) environment for the analysis of the sensorimotor processes underlying learning of object grasping and manipulation. This study was inspired by recent grasping studies indicating that subjects learn skilled manipulation by concurrently modulating digit placement and forces as a function of the position of object center of mass (CM) in a...

Object-oriented frameworks have become a key element in the design of distributed systems. They make the existence of the physical and operating system level resources transparent to the designer and provide the abstract view of the distributed systems as a set of ob-view of the distributed systems as a set of objects that interact by invoking well-defined interfaces of each other. Easy reuse o...
