A Flexible Infrastructure for Dynamic Power Control of Electric Vehicle Battery Chargers [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2016
This paper proposes a flexible infrastructure for dynamic power control (FIDPC) of electric vehicle (EV) battery chargers. This infrastructure dynamically adjusts the EV battery charger current, according to the power demand of the home wherein the vehicle is plugged. An infrastructure was implemented to validate this proposal.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

open access: yesAdvanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
