Multistable Composite Laminate Grids as a Design Tool for Soft Reconfigurable Multirotors

Advanced Intelligent Systems, EarlyView.
Flexible, lightweight, stable: the reconfigurable multirotor combines stable flight in multiple shapes with low‐energy reconfiguration. Utilizing optimized multistable composites, it achieves self‐locking in open and folded configurations, cutting width‐span by 48% and allowing for safe gap traversal.

A Study on the Effect of Structural Compliance Placing in Soft Contact/Collision Properties of Multirotor Micro Aerial Vehicles

Advanced Intelligent Systems, EarlyView.
This article answers the question “Where is the best place to apply compliance in a multirotor micro aerial vehicle to make it more collision‐resilient?” by analyzing the output data of more than 1200 drone collision tests for four main configurations of micro‐quadcopters each possessing a unique softness layout of physical frame.

Spring and Power in Hovering Ornithopters

Advanced Intelligent Systems, EarlyView.
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Sensorless Human–Robot Interaction: Real‐Time Estimation of Co‐Grasped Object Mass and Human Wrench for Compliant Interaction

Advanced Intelligent Systems, EarlyView.
To tackle the challenge of parameter estimation in dynamic human–robot interaction, this research proposes a novel method that integrates a disturbance observer with Kalman filtering. In contrast to conventional techniques, this approach facilitates the simultaneous real‐time estimation of human wrench and object parameters, offering significantly ...
