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 ...

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Advanced Science, EarlyView.The Species Search Engine (KISSE) is a novel statistical approach for identifying species from collagen peptides, using a curated library of sequences and their relative abundances derived from shotgun proteomics. Abstract DNA and bone collagen are two key sources of resilient molecular markers used to identify species from their remains.
