Current forms of distributed manipulation include multiple mobile robots, vibrating plates, actively controlled arrays of air jets, and planar micro and macro-mechanical arrays of actuators. The paper presents a form of distributed manipulation using passive air flow fields, which has been experimentally demonstrated. Rather than directly actuating the flow at each point, potential flow assumptions allow a small number of simple point-generated fields to combine to form complex manipulation fields. The paper presents a methodology for efficiently computing equilibria of objects manipulated by arbitrary combinations of radially symmetric fields (such as potential flow fields).","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

More sophisticated models result in higher quality but the use in embedded real-time control systems imposes strict requirements on timing, memory allocation, and robustness. To satisfy these constraints, the model implementation is often optimized by manual coding, an unwieldy and error prone process. The paper presents an approach that exploits code synthesis from high level intuitive and convenient multi-body system (MBS) model descriptions. It relies on an object-oriented C++ library of MBS components tailored to the computations required in robot control such as forward and inverse kinematics, inverse dynamics, and Jacobians. Efficient model evaluation algorithms are developed that apply to multi-body tree structures as well as kinematic loops that are solved analytically for a certain class of loop structures.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

This paper presents a novel fault tolerant localization algorithm developed for centimeter-scale robots, called Millibots. To determine their locations, the Millibots measure the distances between themselves with an ultrasonic distance sensor. They then combine these distance measurements with dead reckoning in a maximum likelihood estimator. The focus of this paper is on detecting and isolating measurement faults that commonly occur in this localization system. Such failures include dead reckoning errors when the robots collide with undetected obstacles, and distance measurement errors due to destructive interference between direct and multi-path ultrasound wavefronts. Simulations show that the fault tolerance algorithm accurately detects erroneous measurements and significantly improves the reliability and accuracy of the localization system.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

In this paper, we investigate the computational mechanisms for visual attention in such a system. Stimuli in the environment excite a dynamical neural network that implements a saliency map, i.e., a winner-take-all competition between stimuli while simultaneously smoothing out noise and suppressing irrelevant inputs. In real-time, this system computes new targets for the shift of gaze, executed by the head-eye system of the robot. The redundant degrees-of-freedom of the head-eye system are resolved through a learned inverse kinematics with optimization criterion. We also address important issues how to ensure that the coordinate system of the saliency map remains correct after movement of the robot. The presented attention system is built on principled modules and generally applicable for any sensory modality.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

It is necessary to know his behavior over the long term. The ideal intelligent support system can measure the data about human actions in the daily life, accumulate them, understand the behavior and the patterns thereof, and adapt thereto. An accumulation and summarization system of human daily action data based on sensing in 1 room, \"Robotic Room II\", is designed and the accumulation system integrating with the measurement parts is implemented. It is confirmed that accumulation over the long term is possible by experiments for accumulation of human action data in ordinary life. Moreover, as the first step of an analysis of the accumulated data, a summarization algorithm based on the changes of the room states is proposed. It is confirmed that the summarized data enables us to catch the most of the changes of the room states. Finally, a possibility of application for life monitoring by means of summarization is also illustrated.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

Use of a performance index such as the condition number of the Jacobian matrix that is composed of nonhomogeneous physical units may lack physical significance. In order to avoid unit mismatch in the Jacobian matrix, the paper presents a new Jacobian formulation by use of three point generalized coordinates, which results in a (9/spl times/9) dimensionally homogeneous Jacobian matrix. The condition number of the new Jacobian matrix is used to design an optimal architecture or pose of parallel manipulators for best dexterity. A design example with a Gough-Stewart platform parallel manipulator by using the proposed formulation is shown to generate the same optimal configuration as from using the other Jacobian formulation methods.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

The controller is based on a few simple ideas: (1) control the legs vertically using force control and horizontally using position control; (2) use simple rules to distribute leg forces; (3) the supporting surface should not have to be horizontal, planar or even static; (4) since the height is not easily defined for a legged robot, the average of the \"leg heights\" is used. This controller is successfully tested in both simulations and experiments. It is capable of adjusting to step changes in reference posture, as well as standing on a moving balance board. Finally, we suggest tests to benchmark posture controllers.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.
