Sub‐Micrometer‐Precision Path Following of Piezo‐Actuated Mobile Robot
Advanced Intelligent Systems, EarlyView.This article reports on the Holonomic‐Beetle (HB), a palm‐sized robot that achieves sub‐micrometer (sub‐µm) precision path tracking across spatial ranges from 100 µm to 10 mm. Using proportional‐integral‐derivative (PID) control, the HB accurately tracks both complex and straight paths with sub‐µm path errors, surpassing existing robots.

Data Reliability Enhancement for Wind-Turbine-Mounted Lidars
Remote Sensing, 2022 Wind lidars can be used on wind turbines to monitor the inflow for power curve verification and for control purposes. In these applications, the lidar is most often placed on the nacelle behind the rotating blades, which occasionally intercept the line ...

Object Detection From a Few LIDAR Scanning Planes [PDF]
IEEE Transactions on Intelligent Vehicles, 2019 LIDAR sensors enable object and free-space detection for intelligent transportation systems and vehicles. This paper proposes a recognition method for LIDARs based on only a few detection planes. This method is useful especially in the case when the angular resolution of the scan is sufficient, but in the vertical direction the planes are far from each

Lidar Measurement Bias Estimation via Return Waveform Modelling in a Context of 3D Mapping
, 2019 In a context of 3D mapping, it is very important to get accurate measurements from sensors. In particular, Light Detection And Ranging (LIDAR) measurements are typically treated as a zero-mean Gaussian distribution.

Validation of sentinel-1A SAR coastal wind speeds against scanning LiDAR [PDF]
, 2017 High-accuracy wind data for coastal regions is needed today, e.g., for the assessment of wind resources. Synthetic Aperture Radar (SAR) is the only satellite borne sensor that has enough resolution to resolve wind speeds closer than 10 km to shore but ...
