Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

Advanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Response of the Effelsberg 100m radio telescope to signals in the near-field at 24 GHz [PDF]

Advances in Radio Science, 2003
Short range radar (SRR) for cars has been proposed to operate over 5 GHz of bandwidth at the 24 GHz ISM band. To estimate the level of interference from these devices on radio telescopes, the near-field antenna pattern has to be known.

Hierarchically Engineered Flame‐Retardant Triboelectric Yarn Exhibiting Robust Mechanical Performance and Humidity‐Boosted Electrical Output for Firefighting Applications

Advanced Science, EarlyView.
Inspired by a high‐temperature‐resistant wire, a Super Intelligent Fireproof Yarn is developed through the technology of hierarchical textile assembly. This yarn exhibits high tensile strength, shear resistance, and excellent flame‐retardant performance, and achieves humidity‐enhanced triboelectric output, enabling it to meet the demands of extreme ...
