Toward Observation of Human Assembly Skill Using Virtual Task Space

چکیده
This paper presents a methodology for observing human skill by using a virtual task space constructed by the haptic virtual reality technology. First a haptic simulator developed for a 2-dimensional pegin-hole assembly operation in the virtual environment is presented. To examine the validity of the simulator, a comparison study between the peg-in-hole task using the simulator and that in the real world is performed. It is hoped that this simulator will help in gathering data of human skill in assembly tasks and analyzing the human skill. Secondly, a method for improving the stability of this kind of haptic simulator by using an analog electric circuit for driving the motors of the haptic interface device is presented. It is analytically shown that the stability is improved by this method using the passivity theory. Preliminary experimental results are given to demonstrate the validity of this analog circuit.

متن کاملTransfer of manipulation skills from human to machine through demonstration in a haptic rendered virtual environment
Robots are widely used as automation tools to improve productivity in industry. Force sensitive manipulation is a generic requirement for a large number of industrial tasks, especially those associated with assembly. One of the major factors preventing greater use of robots in assembly tasks to date has been the lack of availability of fast and reliable methods of programming robots to carry ou...
متن کاملH . Onda , T . Suehiro and K . Kitagaki Teaching by Demonstration of Assembly Motion in VR - Non - deterministic
"Teaching by Demonstration" is a method of generating a robot program that makes a robot do the same task as the task that a human operator demonstrates. We have developed a "teaching by demonstration in VR" system that automatically generates a robot program to work in the real world after a task is demonstrated by an operator in the virtual world. This system generates a program that detects ...
متن کاملSimultaneous Multi-Skilled Worker Assignment and Mixed-Model Two-Sided Assembly Line Balancing
This paper addresses a multi-objective mathematical model for the mixed-model two-sided assembly line balancing and worker assignment with different skills. In this problem, the operation time of each task is dependent on the skill of the worker. The following objective functions are considered in the mathematical model: (1) minimizing the number of mated-stations (2), minimizing the number of ...
