  • arcsnake reconfigurable snake like robot with archimedean Screw Propulsion for multi domain mobility
    arXiv: Robotics, 2021
    Co-Authors: Florian Richter, Peter V Gavrilov, Hoi Man Lam, Amir Degani, Michael C Yip
    Abstract:

    Exploring and navigating in extreme environments, such as caves, oceans, and planetary bodies, are often too hazardous for humans, and as such, robots are possible surrogates. These robots are met with significant locomotion challenges that require traversing a wide range of surface roughnesses and topologies. Previous locomotion strategies, involving wheels or ambulatory motion, such as snake platforms, have success on specific surfaces but fail in others which could be detrimental in exploration and navigation missions. In this paper, we present a novel approach that combines snake-like robots with an Archimedean Screw locomotion mechanism to provide multiple, effective mobility strategies in a large range of environments, including those that are difficult to traverse for wheeled and ambulatory robots. This work develops a robotic system called ARCSnake to demonstrate this locomotion principle and tested it in a variety of different terrains and environments in order to prove its controllable, multi-domain, navigation capabilities. These tests show a wide breadth of scenarios that ARCSnake can handle, hence demonstrating its ability to traverse through extreme terrains.

  • Design and development of a magnetic lead Screw Propulsion device for general transport system
    Iet Electric Power Applications, 2020
    Co-Authors: Zhijian Ling, Wenxiang Zhao, Peter Omand Rasmussen
    Abstract:

    This study proposes a magnetic lead Screw (MLS) as a continuous Propulsion device for the general transport system (GTS). By integrating the outer rotor machine with the MLS, it is possible to construct a high force design with the improved operating surface area. Initially, a brief statement of the novel GTS is given, leading to an introduction of the MLS. Besides, a scaled 2.6-kN MLS demonstrator is presented to verify the Propulsion principle and thrust force. Furthermore, the MLS design focuses on several types, which use different materials and magnetic structures. The three-dimensional finite element analysis is used to optimise design, with the goal of force performance. Moreover, the shear stress, cost-effectiveness, magnetic losses, and mechanical stress of the different topologies are compared, revealing that the MLS made by ferrite magnet is more suitable for employed in GTS applications. Finally, a dynamic model of the GTS is developed to verify the acceleration and speed responded.
