This study aims to describe the development and application of novel long, continuous backbone hose and cable robots. These continuum robots can actively control the bending along their compliant backbones. This feature allows them to both enter into and maneuver and operate within tight spaces that neither conventional robots nor people can access. Equipped with cameras and other sensors, these robots provide new capabilities in remote inspection, and when used as hoses, enable novel applications in dirty and dangerous environments. This paper discusses the design and implementation of two such types of novel robots: (1) a long, thin tendril cable robot for remote visual inspection; and (2) a novel active hose robot for pumping viscous fluids. The deployment of the cable robot in novel applications, including inspection of equipment racks on the International Space Station, is reviewed. Application of the hose robot to novel robotic 3D concrete applications and the effects of the pumping dynamics on the operation of the hose robot are also discussed. Owing to the developments in robotics, this study has provided useful insights and opened up various avenues for further exploration.
