Fast Path Computation using Lattices in the Sensor-Space for Forest Navigation

Published in 2021 IEEE International Conference on Robotics and Automation (ICRA), 2021

This paper presents a motion planning strategy that relies on lattices for the fast computation of local paths that both avoid obstacles and follow a vector field that encodes the global robot task.

Parametric Investigation of the EESC-USP Aeroacoustic Fan Rig

Published in 31st Congress of the International Council of the Aeronautical Sciences (ICAS), 2018

A parametric campaign was conducted at the EESC-USP low speed Fan Rig. In it, was changed the parameters: shaft speed, rotor-stator spacing and throttling.

Design of an Instrumented Stator Vane for Unsteady Pressure Measurements using MEMS Microphones

Published in 31st Congress of the International Council of the Aeronautical Sciences (ICAS), 2018

In this work, an instrumented stator vane was designed using recently available technologies, as 3D printing and the use of MEMS microphones, to measure this pressure fluctuations. Phase-averaging and the signal from a hall sensor were used to separate broadband content in time series.
