In this paper, we report on the design of a 6 Degrees-Of-Freedom (6-DOF) motion tracking system for a MicroAerial-Vehicle (MAV) using stereo-vision. The pose measurement is performed by tracking the 3D positions of a marker (three targets) attached to the MAV. This task involves determination of optimal sensor placement for the stereo system and an orientation calculation algorithm. Experiments...

Recent years have seen an increased interest in Micro Air Vehicles (MAVs) with applications ranging from search-and-rescue to mimicking insect behavior. MAVs have several challenging design requirements that impact processor design. These include real time processing demands and severe power/weight budgets. In this paper, we describe the characteristics of MAV applications and propose hardware ...

The proviral DNA of chicken peripheral blood leukemic myeloblasts was analyzed by restriction endonuclease digestion and Southern blotting. Two restriction endonuclease-generated fragments, an EcoRI 2.2-megadalton (Md) and a HindIII 2.6-Md fragment, were present upon enzyme cleavage of all leukemic myeloblast DNA preparations in addition to endogenous or helper-specific fragments. Neither of th...

A new differential game which admits a “closed form” solution is analyzed. In this paper guidance laws are developed to optimally position a relay Micro-UAV (MAV) to provide an operator at the base with real-time Intelligence, Surveillance, and Reconnaissance (ISR) by relaying communication and video signals when the rover MAV performing the ISR mission is out of radio contact range with the ba...

The work presented in this paper is a part of research work on autonomous navigation for Micro Aerial Vehicles (MAVs). Simultaneous Localization and Mapping (SLAM) is crucial for any task of MAV navigation. The limited payload of the MAV makes the single camera as best solution for SLAM problem. In this paper the Large Scale Dense SLAM (LSD-SLAM) pose is fused with inertial data using Smooth Va...

In this work, a new combined vision technique (CVT) is proposed, comprehensively developed, and experimentally tested for stable, precise unmanned micro aerial vehicle (MAV) pose estimation. The CVT combines two measurement methods (multiand mono-view) based on different constraint conditions. These constraints are considered simultaneously by the particle filter framework to improve the accura...

The purpose of this study was to identify the role of humeral elevation of the non-throwing arm in relation to maximum ball velocity (MBV) in unconstrained overarm throws in children aged 12-14. 3D motion analysis was used to investigate the throwing technique of 144 students. The group was classified as ‘skilled’ or ‘less skilled’ based on MBV at release. Joints kinematics and timing of segmen...

طبقه‌بندی حرکت‌های اعضای دیستال با استفاده­از سیگنال‌های الکترومایوگرام سطحی (sEMG) قسمت پروکسیمال، بخش مهمی در کنترل پروتزهای مایوالکتریک است. در بیش­تر مطالعات قبلی، طبقه‌بندی تعداد محدودی از حرکت‌های دست، مورد بررسی قرار گرفته­است. در این مقاله، از پایگاه داده‌ی NINAPROکه شامل داده‌های کینماتیک و sEMGفرد سالم برای 52 حرکت انگشت، پنجه و مچ دست است استفاده شد. عملکرد طبقه‌بندی کننده‌های LDAو L...
