Bronchoscope Tip Localization With Learned Airway Constraints and an Open Source Simulator

Advanced Intelligent Systems, EarlyView.
BronchoLoc addresses feature‐poor bronchoscopic imaging by combining monocular video with a preoperative CT graph to estimate 3D camera location. A local tracker identifies candidate branches, while a sequence‐aware global module refines the trajectory. Demonstrating sub‐centimeter accuracy across synthetic and phantom datasets, this framework advances

Tracking the soccer ball using multiple fixed cameras [PDF]

, 2009
This paper demonstrates innovative techniques for estimating the trajectory of a soccer ball from multiple fixed cameras. Since the ball is nearly always moving and frequently occluded, its size and shape appearance varies over time and between cameras ...

Compliant Footpads Enable Terrain‐Adaptive Hopping in a Monopedal Robot

Advanced Intelligent Systems, EarlyView.
A lightweight compliant footpad with embedded spines lets a monopedal hopping robot keep stable ground contact. It preserves stance‐phase dynamics and enables reliable hopping on rock, sand, and ice. Monopedal hopping robots offer exceptional mobility over discontinuous terrain but require consistent foot‐ground contact to maintain stance‐phase ...

Beyond the Camera: Epidermal Sensor Platforms for Intelligent Facial Expression Recognition and Interactive Human Monitoring

Advanced Intelligent Systems, EarlyView.
Skin‐conformal epidermal sensors enable camera‐free intelligent facial monitoring by converting facial deformation and muscle activity into electrical signals through piezoresistive, capacitive, electrophysiologic, and self‐powered mechanisms. Coupled with artificial intelligence (AI), these platforms support facial expression recognition, human ...

Motion of a ball attached to a mass via a hole in a horizontal table

Physics Education
Abstract Measurements are presented of the circular motion of a ball on a table attached to another ball by a length of thread via a hole in the table. It is a standard problem often assigned to students, but the experimental results differ from predictions.

A Hierarchical, Model‐Based System for High‐Performance Humanoid Soccer

Advanced Intelligent Systems, EarlyView.
A hierarchical model‐based humanoid soccer system built on ARTEMIS integrates compliant mechanism design, in‐gait kicking, perception, localization, collision‐aware navigation, and behavior planning. Hardware–software codesign aligns mechanical design and control strategy with the requirements of autonomous soccer.

Failure of attachment strategies and the adaptive value of desperation: Cabo’s choice.

, 2008
The exposure to maltreatment and to conditions of danger during childhood and adulthood is very common among humans. In serious conditions of danger, when attachment strategies fail, adaptive defensive reactions can manifest themselves: the alternation ...

An Active Knee–Ankle–Foot Orthosis With Torque‐Dense, Low‐Impedance Knee Actuation

Advanced Intelligent Systems, EarlyView.
This article presents the simulation, design, and clinical validation of a robotic active KAFO with torque‐sensitive actuation. By passively and continuously adapting the transmission ratio in response to the knee torque, the torque‐sensitive actuator overcomes the tradeoff between torque, weight, and impedance observed in conventional robot actuators,
