Learning Ground Traversability from Simulations

, 2018
Mobile ground robots operating on unstructured terrain must predict which areas of the environment they are able to pass in order to plan feasible paths. We address traversability estimation as a heightmap classification problem: we build a convolutional

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.

A safe reinforcement learning approach for autonomous navigation of mobile robots in dynamic environments

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract When deploying mobile robots in real‐world scenarios, such as airports, train stations, hospitals, and schools, collisions with pedestrians are intolerable and catastrophic. Motion safety becomes one of the most fundamental requirements for mobile robots.

Consensus Control for Wheeled Mobile Robots Under Input Saturation Constraint

IEEE Access, 2020
In this article, the consensus control problem for the nonholonomic wheeled mobile robots under the input saturation constraint is addressed. The specified-time observer is designed to estimate the root node's linear speed and angular speed by only using

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,

A Canine Musculoskeletal Robot for Investigating Biomechanical Functions During Locomotion

Advanced Robotics Research, EarlyView.
In this study, a dog limb musculoskeletal robot was developed using thin McKibben artificial muscles to investigate the effects of the dog's musculoskeletal structure on walking. Walking experiments were conducted in both indoor and outdoor environments, suggesting that the flexible structure of the dog's shoulders contributes to an increase in stroke ...

Four-wheel, eight-wheel drive mobile robot design

Journal of Physics: Conference Series
Abstract The purpose of this paper is to design and analyze a mechanical system of a four-wheeled eight-wheel drive mobile robot to cope with complex terrain and high-load environments. The walking and steering systems are designed to be independently driven by brushless DC motors for each wheel. The chassis structure is optimized.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

Advanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.
