A Vacuum‐Suction and Rotate End Effector for Robotic Apple Fruitlet Thinning: Comparative Development, Integrated Field Evaluation, and Preliminary Harvesting

Advanced Intelligent Systems, EarlyView.
Robotic apple thinning is constrained by a single field season confined to a few weeks each year. An efficient design process screens four detachment concepts off‐season using an artificial fruitlet structure, with field trials identifying vacuum suction and rotation as the most effective approach.

Drag Force for a Burning Particle [PDF]

Combustion and Flame, 2020
Abstract Fully-resolved simulations of a burning char particle are performed to understand the effects of chemical reactions on the drag force by using the ghost cell immersed boundary method. The momentum, heat and mass transfers at the interface are all considered.

Drag forces in granular materials

Soft Matter
This tutorial review introduces some non-trivial properties of the drag force experienced by objects moving through granular materials, including dependencies on the velocity of the object and the pressure around it, and associated scaling laws.
