Stable Imitation of Multigait and Bipedal Motions for Quadrupedal Robots Over Uneven Terrains

Advanced Robotics Research, EarlyView.
How are quadrupedal robots empowered to execute complex navigation tasks, including multigait and bipedal motions? Challenges in stability and real‐world adaptation persist, especially with uneven terrains and disturbances. This article presents an imitation learning framework that enhances adaptability and robustness by incorporating long short‐term ...

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.

A scalable convolutional neural network approach to fluid flow prediction in complex environments

Scientific Reports
We evaluate the capability of convolutional neural networks (CNNs) to predict a velocity field as it relates to fluid flow around various arrangements of obstacles within a two-dimensional, rectangular channel. We base our network architecture on a gated

Formation Control of Multi‐Agent System with Local Interaction and Artificial Potential Field

Advanced Robotics Research, EarlyView.
This article proposes a local interaction‐based formation control method for Multi‐Agent system, integrating consensus and leader‐follower strategies with a stress response mechanism—artificial potential field to reduce communication overhead and enable obstacle avoidance. Experimental results on triangular, square, and hexagonal formations confirm its

Multi-agent VFH+ flocking control with escaping dynamic equilibrium under complex obstacles

Complex & Intelligent Systems
Flocking control is essential for studying the collective behavior of agents in multi-agent systems (MASs). Most existing flocking control algorithms assumed that the motion of the agent was influenced by consensus, gradient-based, and navigation ...

Adaptive Velocity Obstacle Avoidance for Multi-Vessel Encounters

2024 UKACC 14th International Conference on Control (CONTROL)
Numerous methodologies based on velocity obstacles have been developed for marine collision avoidance over the past decade. They are typically limited to one or two ship encounters, sequential ship encounters and/or lack safety guarantees in scenarios involving multiple obstacles.
