Robotics for Crop Pollination: Recent Advances and Future Direction

Journal of Field Robotics, EarlyView.
ABSTRACT There is great interest in alternative pollination strategies for crop production in the face of climate change and perennial threats to the traditional pollination mechanisms. This review explores the potential of robotic pollination as a promising solution to these challenges affecting crop fertilization, agricultural sustainability, and ...

On-Surface Locomotion of Particle Based Microrobots Using Magnetically Induced Oscillation

Micromachines, 2017
The low Reynolds number condition presents a fundamental constraint on designing locomotive mechanisms for microscale robots. We report on the use of an oscillating magnetic field to induce on-surface translational motion of particle based microrobots ...

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Surface Locomotion of Cell‐Sized Microrobots Subject to Adhesive Heterogeneity

Small, EarlyView.
Chemically powered, cell‐sized microrobots exhibit translational, circular, or spiral motion through a balance among self‐phoretic propulsion, drag, gravity, and heterogeneous surface interactions. Experiments show that microrobot design and substrate conditions regulate both mobility and trajectory type.

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

Small, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...

Composite Microgels with Dynamically Switchable Stiffness

Small, EarlyView.
Composite microgels comprising alginate and mucin are produced, in which covalent and ionics cross‐links are combined such that the mechanical properties of the microgels can be tuned on demand at any time post‐production. In addition, the mucin component conveys bacteria‐repellent properties to the cytocompatible microgels.
