— This paper addresses the problem of coordinated path following of multiple wheeled mobile robots while keeping a desired formation. The control laws proposed are categorized into two envelopes, one is steering individual robots to trace along predefined paths, and the other is ensuring tracked paths to be well defined in the formation, by means of(More)
—This paper addresses the problem of coordinated path tracking for networked nonholonomic mobile vehicles, while building and keeping a desired formation. The control laws proposed are categorized into two envelopes by integrating individual path tracking and global virtual structure approaches. One is steering individual vehicles to track virtual vehicles(More)
The involvement of OsKASI in FA synthesis is found to play a critical role in root development of rice. The root system plays important roles in plant nutrient and water acquisition. However, mechanisms of root development and molecular regulation in rice are still poorly understood. Here, we characterized a rice (Oryza sativa L.) mutant with shortened(More)
— This paper addresses the problem of simultaneous path following control, obstacle avoidance and collision free for coordinated multiple nonholonomic autonomous vehicles under formation constraints. Global heading guidance design is highlighted in individual path following and augmented for obstacle avoidance between vehicles and obstacles. Within a(More)
