Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced 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.

An Oscillation criteria for second order functional equations
Acta Mathematica Scientia, 2002 The authors consider the second-order linear functional equation \[ x\bigl(g(t)\bigr) =P(t)x(t)+Q(t)x \bigl(g^2(t)\bigr),\;t\geq t_0, \] where \(P,Q,g:[t_0,\infty) \to[0,\infty)\) are given function, \(t_0\geq 0\), \(g\neq id|_{[t_0,\infty)}\), \(\lim_{t\to\infty} g(t)=\infty\).

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Oscillation criteria for second-order nonlinear perturbed differential equations
Electronic Journal of Differential Equations, 2014 In this article, we study the oscillation of solutions to the nonlinear second-order differential equation $$ \Big(r(t)\psi(x(t))|x'(t)|^{\alpha-1}x'(t)\Big)' +P(t,x'(t))\psi(x(t))+Q(t,x(t))=0. $$ We obtain sufficient conditions for the oscillation

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators
Advanced Robotics Research, EarlyView.We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.
