This paper discussed the possibility of deploying the proposed Variable Geometry Tracked Vehicle (VGTV) in our first robotic based prototype called REC-01. REC-01 is being developed as a miniature scouting and search & rescue all-terrain robotic vehicle. Its comparatively small size and mass limit its power capacity and navigational capabilities for larger obstacles. The VGTV is a unique concept used to overcome these shortcomings. The main part of this paper is to discuss the mechanical efficiency of the tracked systems in some specific field conditions and compare the results with the conventional tracked propulsion. The outcomes of the first prototype are also briefly discussed in this paper.

Recent years have witnessed the advancement of the Internet of Things (IoT) and its emergence as a technology that could revolutionize many businesses. It helps considerably in creating data-driven business models with the insights it provides. IoT systems are deployed in data collection, monitor processes, provide insights and allow businesses to make data-driven productivity improvements. However, IoT systems are often experiencing data loss due to inevitable failures ranging from devices, networks, to the application layer, especially in scarce infrastructure resources environments. Data loss might be unrecoverable in many circumstances. As such, this research presents a blockchain based IoT model (framework) with the aim of circumventing data loss. We envisioned IoT blockchain technology in enhancing data veracity with data loss tolerance. That is, to have blockchain enhancing the IoT data veracity by leveraging on the features existed in its peer-to-peer network (P2P) and distributed ledger storage technology (DLT). Additionally, the edge computing of IoT blockchain technology is also conceptually workable; with intelligent small computing resources, it opens up a new era of bringing the intelligence of data collection, connectivity, computation and storage into the edge/device layer. A novel IoT blockchain strength monitoring system is also been studied to further enhance data veracity; this is achieved through a capacitance monitoring on the IoT blockchain system. The empirical results show that the proposed IoT blockchain with a strength monitoring model can alleviate data loss and thus enhance data veracity with data loss tolerance.
