The rapid advancement of flexible robotic arm technology has revolutionized operations across critical domains, from minimally invasive surgical interventions and precision automotive assembly to extreme-environment tasks like satellite maintenance and deep-sea exploration. Central to this transformation are electric, pneumatic, and hydraulic drive systems—each embodying unique trade-offs between precision, force density, flexibility, and environmental adaptability. Electric actuators, for instance, deliver sub-micron positioning for surgical robots, while pneumatic systems excel in safe human-robot collaboration, and hydraulic drives dominate heavy-load scenarios. Yet, as detailed in preceding analyses of drive system designs and applications, the path toward robust, scalable, and autonomous deployment of flexible robotic arms remains hindered by profound technical barriers.
