Multi-robot manipulation tasks can be complicated, due to the need for tight temporal coupling between the robots. However, this is an ideal scenario for human-agent-robot teams, since performing all of the manipulation aspects of the task autonomously is not feasible without additional sensors. To ameliorate this problem, we present a paradigm for allowing subjects to configure a user interfac...

Human environments present special challenges for robot manipulation, since they are complex, dynamic, uncontrolled, and difficult to perceive reliably. For tasks that involve two handheld objects, the use of two arms can help overcome these challenges. With bimanual manipulation, a robot can simultaneously control two handheld objects in order to better perceive key features, control the objec...

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...

This paper describes an empirical study on object assembly in a virtual environment. The study evaluates the effectiveness and correlation of the following two manipulation supporting methods: “discrete placement constraints” and “collision avoidance” in both two-handed and collaborative virtual objects assembly. The results show that discrete placement constraints need practice to handle objec...

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...

The study of cooperative work as a socially-situated activity has led to a focus on providing 'mechanisms' that more closely resonate with existing work practice. In this paper we challenge this approach and suggest the flexibly organised nature of work is better supported when systems provide a 'medium' which can be tailored to suit each participant's needs and organised around the detail of t...

Biological market theory is potentially useful for understanding helping behaviour in animal societies. It predicts that competition for trading partners will affect the value of commodities exchanged. It has gained empirical support in cooperative breeders, where subordinates help dominant breeders in exchange for group membership, but so far without considering one crucial aspect: outside opt...

This paper presents a conceptual model for hypermedia systems that, among other features, supports versioning, permits exploring and managing alternate configurations, maintains document histories, supports cooperative work and provides automatic propagation of version changes. In general, the model was designed to minimize the cognitive overhead imposed on the user by version manipulation. The...

This work presents force control in dual arm planar cooperative space robot for cooperative manipulation by two arms. A docking operation by the two arms of the space manipulator has been carried out. During docking operation, space robot requires mechanical interaction with compliant objects, which encounter force and motion constraints. The gripping force should be such that the object should...
