Event-Based Closed-Loop Control for Path Following of a Purcell’s Three-Link Swimmer

Robotics
Purcell’s three-link swimmers, characterised by segments connected through one-degree-of-freedom joints, exhibit a difficulty in following precise paths.

Precise path planning and trajectory tracking based on improved A-star algorithm

Measurement + Control
Path planning and trajectory tracking are very meaningful for the field of autonomous driving, but currently path planning still has problems such as non-optimal paths and insufficiently accurate paths.

Vaccination Strategies: Mixing Paths Versus Matching Tracks

Vaccines
Vaccination strategies play a pivotal role in achieving broad and robust immune protection. With the advent of new technologies and challenges posed by emerging infectious diseases such as SARS-CoV-2, evaluating the efficacy of homologous (matching tracks) and heterologous (mixing paths) vaccination regimens is critical.

Path planning for oversized cargo vehicles considering three-dimensional collision risks

智能科学与技术学报
To address three-dimensional collision risks associated with oversized cargo vehicles and enhance path smoothness and tracking accuracy, a closed-loop iterative path planning method is proposed for oversized cargo vehicles. First, a basic path is planned
