Semianalytical Approximation of the Fluid Drag in Projectile Motion Using Newton's Equation of Motion

Journal of Applied Mathematics
A body moving in a fluid experiences some of the fluid-induced forces, which may derail the body from its fluid-free trajectory and consequently transform its maximum height reached, time of flight, and range.

Push the Limits: Human‐Like Multimodal Extreme Embodied Intelligence for Autonomous Racing

Advanced Robotics Research, EarlyView.
Autonomous racing tests embodied intelligence under extreme control limits of speed, actuation, and decision‐making. Inspired by human multimodality, we present Apex, an embodied agent deployed on a super‐formula racing car at Yas Marina. Integrating physics‐informed perception, multimodal learning, and tasking, Apex cuts lap times by 15% and achieves ...
