Micro aerial vehicles (MAV) are restricted in their size and weight, making the design of sensory systems for these vehicles challenging. We designed a small and lightweight continuously rotating 3D laser scanner—allowing for environment perception in a range of 30 m in almost all directions. This sensor is well suited for applications such as 3D obstacle detection, 6D motion estimation, locali...

شبیه سازی جریان اطراف بال حشرات، نقش مهمی در توسعه ریز پرنده ها(mav) دارد. در کار حاضر شبیه سازی جریان به کمک نرم افزار اوپن فوم(openfoam) و تکنیک تغییر شکل شبکه rbf انجام شده و تاثیر مدل های مختلف سینماتیکی بال بر عملکرد آیرودینامیکی(نسبت ضریب لیفت به درگ)، روی مدل سه بعدی بال حشره در شرایط پروازی ایستا بررسی شد. پارامترهای دخیل در سینماتیک بال شامل زاویه حمله و زاویه انحراف هستند که مقدار بهی...

This paper discusses approaches to cooperative coevolution of form and function for autonomous vehicles, specifically evolving morphology and control for an autonomous micro air vehicle (MAV). The evolution of a sensor suite with minimal size, weight, and power requirements, and reactive strategies for collision-free navigation for the simulated MAV is described. Results are presented for sever...

An experimental study was conducted to assess the acoustic performance of a two-winged Flapping-Wing Micro-Air-Vehicle (FW-MAV) with various wing materials and wing structure configurations for flapping flight applications. It was concluded that highly elastic materials could significantly reduce the flapping wing noise in a wide spectrum of audible frequencies. Furthermore, a dielectric elasto...

Insect flight studies have advanced our understanding of flight biomechanics and inspire micro-aerial vehicle (MAV) technologies. A challenge of centimeter or millimeter scale flight is that small forces are produced from relatively complex wing motions. We describe the design and fabrication of a millimeter-sized wing flapping mechanism to simultaneously control pitch and stroke of insect and ...

We carry out a comprehensive feasibility study for a real-time cm-level localization of a predefined terrestrial target from a MAV-based autonomous platform. Specifically, we conduct an error propagation analysis which quantifies all potential error sources, and accounts for their respective contribution to the final result. Furthermore, we provide a description of a practical MAV system using ...

Abslracl-In this a er we ex lore controllabilit in Wpping R ht for Micro Aeri8&hides (dAVs), inch-size rdo t s ca able oFautonomous Rght Differently from previous work, we focus on a MAV with very limited wmg kinematics and simple input control schemes. In particular, in the first part we show how an MAV provided with a pair of wings, each with a single de ree of freedom and assive rotation, ca...
