in this paper an automatic examination robot was developed to improve the process of cancer detection, tumor localization and geometrical shape diagnosis. a uniformly distributed compressive load was applied to the top tissue surface and the resultant mechanical stress was measured that was employed for the tumor diagnosis task. the experimental examinations were performed on the soft tissue of...

tthe uncertainty estimation and compensation are challenging problems for the robust control of robot manipulators which are complex systems. this paper presents a novel decentralized model-free robust controller for electrically driven robot manipulators. as a novelty, the proposed controller employs a simple gaussian radial-basis-function network as an uncertainty estimator. the proposed netw...

This paper discusses the role of predictability and control in robot-human interaction. This involves the central question whether humans are good models for synthetic (social) agents. Design issues based on cognitive accounts towards robot-human interaction are discussed with respect to the author’s recent work on building interactive robotic systems as remedial tools (teaching devices) for ch...

Previously we have presented a model for generating human-like arm and hand movements on an unimanual anthropomorphic robot involved in human-robot collaboration tasks. The present paper aims to extend our model in order to address the generation of human-like bimanual movement sequences which are challenged by scenarios cluttered with obstacles. Movement planning involves large scale nonlinear...

In this paper we describe the mechanical design, gait and control for a modular hexapod robot which makes it compliant to terrain while climbing slopes up and down. The robot uses a unique electronically actuated 2DOF universal spine similar to the spine of the Snake and the four legged animals like leopard, tiger etc.By controlling the amount of stiffness of the spine we were able to make the ...

We present the application of a vision algorithm based on Harr-like features in Bubblegrams a new mixed reality-based human-robot interaction (HRI) technique. Bubblegrams allows humans and robots working on collocated synchronous tasks to interact directly by visually augmenting their shared physical environment. Bubblegrams uses comics-like interactive graphic balloons or bubbles that appear a...

In order to allow an autonomous robot to perform non-trivial tasks like to explore a foreign planet the robot has to have deliberative capabilities like reasoning or planning. Logic-based approaches like the programming and planing language Golog and it successors has been successfully used for such decision-making problems. A drawback of this particular programing language is that their interp...

In this paper we present a new gesture based control for snake robot using a custom developed accelerometer based data glove. This Snake robot which was biologically inspired was developed for the purpose of search and rescue and serve as a research platform for its locomotion analysis. The locomotion of Snakes is because a differential curve traveling in its body from the head to the tail and ...

The need to understand and model human-like behavior and intelligence has been embraced by a multidisciplinary community for several decades. The success so far has been shown in solutions for a concrete task or a competence, and these solutions are seldom a truly multidisciplinary effort. In this paper we analyze the needs and the opportunities for combining artificial intelligence and bio-ins...

Motivated by a high demand for automated inspection of civil infrastructure, this paper presents a novel design and development of a tank-like robot for structural health monitoring. Unlike most existing magnetic wheeled mobile robot designs, which is only suitable for climbing on flat steel surface, our proposed tank-like robot design uses reciprocating mechanism and roller-chains to make it c...
