Do outgrower schemes enhance technology adoption and productivity? Evidence from maize farmers in Northern Ghana

Agribusiness, EarlyView.
Abstract Nucleus outgrower schemes are contractual arrangements where well‐resourced large‐scale farmers (nucleus farmers) are empowered by development support agencies to take charge of smallholder farmers, by providing them with market access and the necessary training on agronomic practices and farm inputs for production.

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.

Tiling Robotics: A New Paradigm of Shape‐Morphing Reconfigurable Robots

Advanced Intelligent Systems, EarlyView.
Tiling robotics is a novel paradigm of shape‐morphing reconfigurable robots, defining them as polyform‐inspired machines capable of transforming between at least two polymorphic shapes. Various reconfiguration‐enabling and locomotion mechanisms of tiling robots are comparatively analyzed, with the electromechanical developments, along with a proposed ...

An Aerial Robot Achieving Bimodal Flight and Independent Attitude Control through Passive Morphing

Advanced Intelligent Systems, EarlyView.
This article presents a bimodal aerial robot capable of operating in both standard quadcopter and revolving flight modes. With four rotors, it independently controls position and roll‐pitch attitude across five degrees of freedom. The design features passive revolute joints, allowing seamless mid‐air transitions between modes using centrifugal forces ...
