We present an error model for a robot's pose based on triangulation from three landmarks. The model represents each landmark position as a Gaussian distribution and, consequently, factors landmark positional uncertainty into robot pose error. We demonstrate the performance and accuracy of this model through a series of experiments and use the results to explain some of the inconsistencies in earlier results. We also present four metrics for analyzing the output of any Gaussian-based localization error model, demonstrating the metrics' particular applicability to multiple robot localization problems 62. = Sci10-r8-tra-trilateracio.pdf Federico Thomas and Lluís Ros, Revisiting Trilateration for Robot Localization, IEEE Transactions on Robotics, Volume 21, Issue 1, Feb. 2005 Page(s): 93 – 101 - TOF - Error analysis - CAYLEY-MENGER DETERMINANT for computation of dilution of precision 63. = Jon Dattorro, Convex Optimization & Euclidean Distance Geometry, Meboo Publishing USA 2005, ISBN 0976401304 - CAYLEY-MENGER DETERMINANT Semi definite programming 64. = hybrid_trilateration.pdf Kong-Woo Lee, Jae-Byung Park and Beom-Hee Lee, Dynamic localization with hybrid trilateration for mobile robots in intelligent space, Intelligent Service Robotics, Springer Berlin / Heidelberg, Volume 1, Number 3 / July, 2008, Pages: 221-235 - Trilateration Hybrid navigation CAYLEY-MENGER DETERMINANT In this paper, we propose a new localization algorithm based on a hybrid trilateration algorithm for obtaining an accurate position of a robot in intelligent space. The proposed algorithm is also able to estimate a position of the moving robot by using the extended Kalman filter, taking into consideration time synchronization and velocity of the robot. For realizing the localization system, we employ several smart sensors as beacons on the ceiling in intelligent space and as a listener attached to the robot. Finally, simulation results show the feasibility and effectiveness of the proposed localization algorithm compared with existing trilateration algorithms. 65. = iros02pdf.pdf R. Kurazume, S.

For broadband source, time-delayed estimation has been quite popular. 2) In free space, acoustic energy decays at a rate that is inversely proportional to the distance from the source. Therefore, if we take simultaneous acoustic energy measurements emitted from an omni-directional acoustic source at different, known sensor locations. 94. # SoundAttenuation.pdf Silex innovations inc., “Sound Attenuation”, 4/5/2000, http://silex.com/pdfs/Sound%20Attenuation.pdf - general notions in sound - sound absorption 95. # b.pdf - Sound absorption 96. = D.

In this paper, a complete GPS/INS integration technique utilizing GPS carrier phase measurements is proposed. A measurement model of doubledifferenced GPS carrier phase measurements is newly derived in order to be used with the INS error model. Also, an algorithm is suggested to resolve the integer ambiguities of GPS carrier phase measurements by employing MS information. From simulation results, performance of the suggested technique is verified 99. = K. Ohno, T. Tsubouchi, B. Shigematsu, S. Yuta, Differential GPS and odometry-based outdoor navigation of a mobile robot, Advanced Robotics, Volume 18, Issue - 6, Page(s): 611- 635 - odometry/ D-GPS outdoor This paper demonstrates a reliable navigation of a mobile robot in outdoor environment. We fuse differential GPS and odometry data using the framework of extended Kalman filter to localize a mobile robot. And also, we propose an algorithm to detect curbs through the laser range finder. An important feature of road environment is the existence of curbs. The mobile robot builds the map of the curbs of roads and the map is used for tracking and localization. The navigation system for the mobile robot consists of a mobile robot and a control station. The mobile robot sends the image data from a camera to the control station. The control station receives and displays the image data and the teleoperator commands the mobile robot based on the image data. Since the image data does not contain enough data for reliable navigation, a hybrid strategy for reliable mobile robot in outdoor environment is suggested. When the mobile robot is faced with unexpected obstacles or the situation that, if it follows the command, it can happen to collide, it sends a warning message to the teleoperator and changes the mode from teleoperated to autonomous to avoid the obstacles by itself. After avoiding the obstacles or the collision situation, the mode of the mobile robot is returned to teleoperated mode. We have been able to confirm that the appropriate change of navigation mode can help the teleoperator perform reliable navigation in outdoor environment through experiments in the road 100. = Stella, E.; Lovergine, F.P.; Caponetti, L.; Distante, A., Mobile robot navigation using vision and odometry, Proceedings of the Intelligent Vehicles '94 Symposium, 24-26 Oct. 1994 Page(s): 417 – 422 - vision/odometry A cooperation strategy between odometry and a novel visual self-location method for indoor autonomous robot navigation is described. The strategy exploits the a-priori knowledge about the path that the vehicle is going to run, whether to model the odometer uncertainity in order to a-priori define the odometer re-calibration position or to verify the experimental uncertainity following the one modelled in order to update the re-calibration position. The visual self-location method capitalizes on the excellent angular resolution of CCD TV cameras in order to estimate the camera position and orientation and, therefore, the vehicle position 101. = D.

Lumelsky, Sensing, intelligence motion: how robots and humans move in an unstructured world, John Wiley & Sons, Inc, 2006, ISBN 0-471-70740-6 - motion planning and collision avoidance is perhaps the most universal robotic problem. It is also the most “robotic” robotic problem: Whereas other issues and techniques are common to other areas of sciences and engineering, collision avoidance—especially its branch that deals with partial input information (such as from sensors)—is the monopoly of robotics. • Motion planning with complete information, also called in literature the Piano Mover’s model or off-line planning approach. Here the path is computed all at once before the motion starts; in principle, an optimal path can be found in this way. • Motion planning with incomplete information, also called sensor-based motion planning or on-line motion planning, or path planning with uncertainty, or the Sensing–Intelligence–Motion (SIM) paradigm. Here the decision-making is done continuously as the robot moves along, based on on-line information, such as from sensors. By its very nature, an optimal solution is ruled out in this formulation. - Provable Versus Heuristic Algorithms. Another important distinction between algorithms is between provable (other terms: non-heuristic, exact, algorithmic) and heuristic approaches. A provable motion planning algorithm is one for which there is a guarantee that if a path between the starting and target points exist, the algorithm will find one in finite time and without an exhaustive search—or else will conclude in finite time that there is no path if such is the case. We then say that the algorithm converges. To obtain such a guarantee, people go through the trouble of proving the algorithm convergence. An algorithm itself should allow such a proof; for example, the so-called “common sense” strategies—we call them heuristic algorithms—do not allow a proof of convergence and are not likely to be convergent. - The main difficulty is not in proving existence of algorithms that would guarantee a solution (they obviously exist), but in assessing the problem complexity and obtaining a computationally efficient procedure. Reaching a solution means either finding a path or concluding in finite time that no path exists. - In the configuration space the robot shrinks to a point, whereas the surrounding objects—we call them obstacles—are grown accordingly, to compensate for the shrinking robot. - In the algorithms working with polygonial obstacles the computational complexity is proportianal to the number of nodes !!! - in 1736 Euler proposed and solved a problem that was to become famous under the name Koenigsberg Bridge Problem. This work marked the beginning of two new mathematical disciplines, graph theory and topology. It also gives an important insight into the robot motion planning problem… 135. = J. Schwartz, J.

The proposed estimator takes the measurement bias into consideration and improves the location accuracy of a mobile location system. In case that a mobile station (MS) utilizes signals from a set of base stations for its location, the computed location is largely affected by nonline-of-sight (NLOS) error in signal propagation. A constrained optimization method in a three-stage estimation structure is proposed to estimate and eliminate the measurement bias contained in each pseudorange and mainly caused by the NLOS error. A linear observation model of the bias is formulated, and the interior-point optimization technique optimally estimates the bias by introducing a feasible range of the measurement bias. It is demonstrated that the new three-stage estimator successfully computes an accurate location of an MS in a realistic environment setting. The location accuracy of the proposed estimator is analyzed and compared with the existing methods through mathematical formulations and simulations. The proposed estimator efficiently mitigates the effect of a measurement bias and shows that the iterated least square (ILS) accuracy of 118 m [67% distance root-mean-square (DRMS)] can be improved to about 17 m in a typical urban environment 155. = ToA_multipath.pdf Y.

Vehicular Technology, vol. 55, no. 5, pp. 1516-1526, Sep. 2006. - Multipath Wireless geolocation in a multipath environment is of particular interest for wideband communications. The conventional approach makes use of first-arriving signals only. In this paper, we investigate whether and under what conditions processing multipath delays should enhance the positioning accuracy. The best achievable positioning accuracy is evaluated in terms of the Cramer-Rao low bound (CRLB) and the generalized-CRLB (GCRLB), depending on whether prior statistics of non-line-sight (NLOS) induced errors are available. We then show that such prior statics are critical to the accuracy improvement when the multipath delays are processed. Furthermore, the degree of accuracy enhancement depends on two major factors: the strength of multipath components and the variance of NLOS induced errors. The corresponding positioning receivers are also discussed. In previous work (Y. Qi and H. Kobayashi, Proc. 2002 IEEE Int. Conf. on Acoustic Speech and Sig. Proc., pp. 2473-2476, 2002, and Proc. IEEE Vehicle Tech. Conf., pp. 285-288, 2002), we developed an analysis of the timeof-arrival (TOA) positioning method in an NLOS environment, assuming single path propagation.

However, there is no proper location system for indoor scenarios. Research into designing location systems for 802.11 networks is being carried out, so locating mobile devices on global networks (GSM/cellular + GPS + WLAN) finally seems feasible. The technique presented in this paper uses existing wireless LAN infrastructure with minor changes to provide an accurate estimation of the location of mobile devices in indoor environments. This technique is based on round-trip time (RTT) measurements, which are used to estimate distances between the device to be located and WLAN access points. Each RTT measurement estimates the time elapsed between the RTS (Request-to-Send) and the CTS (Clear-to-Send) frame of the 802.11 standard. By applying trilateration algorithms, an accurate estimation of the mobile position is calculated - 158. # Small Robot Sensors.mht – GOOD USE - sensors for small mobile robots 159. = Lesson 11 SONAR 1.ppt – GOOD USE Robert J.
