چکیده

This paper deals with programming-bydemonstration of robot manipulators, where a robot program is created automatically from human demonstrations despite morphological differences in the hand/arm structure. To find a correspondence between observed human motions and desired robot hand motions, we represent the task in hand state space. The hand state definition is perception-invariant and valid for both human and robot. The representation simplifies task reconstruction and preserves the essential part of the reaching motion associated with the grasp. We show how demonstrations of pick-and-place tasks can be interpreted and executed by a general-purpose robot manipulator equipped with a three-finger hand.

A Hand State Approach to Imitation with a Next-State-Planner for Industrial Manipulators

In this paper we present an approach to reproduce human demonstrations in a reach-to-grasp context. The demonstration is represented in hand state space. By using the distance to the target object as a scheduling variable, the way in which the robot approaches the object is controlled. The controller that we deploy to execute the motion is formulated as a nextstate-planner. The planner produces...

Coupled dynamical system based arm-hand grasping model for learning fast adaptation strategies

Performing manipulation tasks interactively in real environments requires a high degree of accuracy and stability. At the same time, when one cannot assume a fully deterministic and static environment, one must endow the robot with the ability to react rapidly to sudden changes in the environment. These considerations make the task of reach and grasp difficult to deal with. We follow a programm...

Programming-by-Demonstration of Reaching Motions using a Next-State-Planner

Programming-by-Demonstration (PbD) is a central research topic in robotics since it is an important part of human-robot interaction. A key scientific challenge in PbD is to make robots capable of imitating a human. PbD means to instruct a robot how to perform a novel task by observing a human demonstrator performing it. Current research has demonstrated that PbD is a promising approach for effe...

State Space Models of Remote Manipulation Tasks

A state variable formulation of the remote manipulation problem is presented, applicable to human supervised or autonomous computer-manipula-tors. A discrete state vector, containing position variables for the manipulator and relevant objects, spans a quantized state space comprising many static configurations of objects and hand. A manipulation task is a desired new state. State transitions ar...

Robot Instruction by Human Demonstration

Conventional methods for programming a robot either are inflexible or demand significant expertise. While the notion of automatic programming by high-level goal specification addresses these issues, the overwhelming complexity of planning manipulator grasps and paths remains a formidable obstacle to practical implementation. This thesis describes the approach of programming a robot by human dem...
