Design Method of Time‐Multiplexed Ultrashort Throw Ratio Projection System with Low Distortion and Uniform Resolution

Advanced Photonics Research, EarlyView.
This work develops an ultrashort throw ratio (UTR) laser projection system using time‐multiplexed micro electro mechanical systems scanning. Trapezoidal distortion via vertical laser incidence control is eliminated and a systematic design method integrating a miniaturized catadioptric objective that maintains uniform optical étendue is proposed.

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 ...

In‐Hand Singulation, Scooping, and Cable Untangling with a 5‐Dof Tactile‐Reactive Gripper

Advanced Robotics Research, EarlyView.
This article presents a two‐fingered gripper with five degrees of freedom and a vision‐based tactile sensor for dexterous in‐hand manipulation. It performs complex tasks such as object singulation within granular media, scooping and precise card insertion, and cable untangling.
