Most micro aerial vehicles (MAV) are flown manually by a pilot. When it comes to autonomous exploration for MAVs equipped with cameras, we need a good exploration strategy for covering an unknown 3D environment in order to build an accurate map of the scene. In particular, the robot must select appropriate viewpoints to acquire informative measurements. In this paper, we present an approach tha...

We have developed a visually based autopilot for Micro Air Vehicles (MAV), which we have called OCTAVE (Optical altitude Control sysTem for Autonomous VEhicles). First we built a miniature MAV and an indoor test-bed. The minihelicopter is tethered to a whirling arm and rotates around a central pole equipped with ground-truth positioning sensors for experimental evaluation. The 100-gram rotorcra...

This study aimed to predict the velocity corresponding to the maximal lactate steady state (MLSSV) from non-invasive variables obtained during a maximal multistage running field test (modified University of Montreal Track Test, UMTT), and to determine whether a single constant velocity test (CVT), performed several days after the UMTT, could estimate the MLSSV. Within 4-5 weeks, 20 male runners...

Neste artigo, abordamos as inter-relações entre alimentação, religião e política com o objetivo de analisar os discursos presentes na comunicação antirracista antiespecista produzida pelo Movimento Afro Vegano (MAV). O afroveganismo tem em seu horizonte fundamentos da interseccionalidade, que entrelaçam marcadores sociais, raciais, gênero, classe outros, concebe expêriencias no combate ao racis...

Three-dimensional mapping is an essential component of autonomous Micro Aerial Vehicle (MAV) navigation. The paper focuses on the 3D spatial representation method MAV to overcome collision problem caused by soft constraints, control error, and planning with center mass inflating occupancy grid map. A fast incremental inflated map construction proposed, which reduces time-consumption increase ra...
