Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Collision Avoidance for Autonomous Surface Vehicles Using Velocity Obstacle and Set-Based Guidance. [PDF]

, 2016
A good and reliable collision avoidance method is essential when operating Autonomous Surface Vehicles (ASVs) at sea. But even though avoiding collisions is the most important part, making sure the ASV's evasive maneuvers makes sense to surrounding ...

A Collision-Free Path-Planning Method for an Articulated Mobile Robot

Applied Bionics and Biomechanics, 2007
In previous works, we treated the collision-free path-planning problem for a nonholonomic mobile robot in a cluttered environment. We used a method based on a representation of the obstacles on the robot's velocity space.

Influence of cylindrical obstacle concentration on flow dynamics in channels: a computational approach to optimizing geometric configurations [PDF]

Proceedings of the International Association of Hydrological Sciences
This study investigates the impact of cylindrical obstacle concentration (C) on flow dynamics in low-slope channels using ANSYS Fluent. Cylinders (D = 12 cm, L = 15 cm) were arranged with varying axial and lateral spacings, producing concentrations from ...

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

Advanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

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,
