Building a basketball robot is a recently launched project at the Institute of Automatic Control Engineering (LSR) for investigating fast manipulation with non-negligible dynamics and changing contact situation. This video presents some preliminary results of the project which is balancing a basketball on a plate. An aluminium plate of which the size is 25 × 40 cm is mounted on the end-effector...

حسگرهای نیرو/گشتاور چند‌مولفه‌ای کرنش‌سنج‌دار، برای اندازه‌گیری همزمان نیروها و گشتاورهای استاتیکی و دینامیکی شامل سه مولفه‌ی نیرو و سه مولفه‌ی گشتاور در دستگاه مختصات دکارتی یک سیستم استفاده می‌شوند. در این تحقیق، یک حسگر نیرو/گشتاور شش‌مولفه‌ای نوع ستونی، با سطح مقطع دایروی توخالی معرفی شده است. به منظور جداسازی الکتریکی مولفه‌های بار اعمالی بر آن و بر پایه‌ی مبانی نظری، الگوهایی خاصی برای نص...

detecting anomalies is an important challenge for intrusion detection and fault diagnosis in wireless sensor networks (wsns). to address the problem of outlier detection in wireless sensor networks, in this paper we present a pca-based centralized approach and a dpca-based distributed energy-efficient approach for detecting outliers in sensed data in a wsn. the outliers in sensed data can be ca...

Transmission of blast waves is a complex phenomenon and the characteristics vary with blast design parameters and geo-technical properties of medium. Frequency of vibration and triggering component for structural excitation generally quantifies safe vibration magnitude. At closer distance or higher elevations than the blast locations, vertical or transverse component will be the first arrival t...

We describe the developed hardware concepts and set-up of the Neuroinformatics robot laboratory. It provides part of the infrastructure for the SFB-360 project D4 “Multisensor Based Exploration and Manipulation” (Additional facilities for this project are contributed by the working group of Prof. Alois Knoll and will be described elsewhere). Central part of the described hardware infrastructure...

Precision machine tools use optical encoders for accurate position feedback [1,2]. A novel encoder based on three cross grid gratings mounted on a thin wall beam and a sensor head consisting of six optical sensing elements was developed to calibrate the linear machine tool axis in six Degrees of Freedom (Figure 1). The feasibility of this device has been tested and verified under laboratory con...

Abntract. This paper discusses how local measurements of threedimensional positions and surface normals recorded by a set of tactile sensors may be used to identify and locate objects, from among a set of known objects. The objects are modeled as polyhedra having up to six degrees of freedom relative to the sensors. w e show that inconsistent hypotheses about pairings between sensed point...
