Simulation Results

This paper presents the design and analysis of the ‘Variable Buoyancy System (VBS)’ for depth control which is an essential operation for all underwater vehicles. We use the ‘Water Hydraulic Variable Buoyancy System (WHVBS)’ method to control the buoyancy and discuss details of the system design architecture of various components of VBS. The buoyancy capacity of the developed VBS is five kilograms and the performance of the VBS in standalone mode is analysed using numerical simulation. Presented VBS is operable to control the buoyancy up to sixty meters of depth and it can be directly installed to medium size UVs. Simulation results show that the developed VBS can reduce the energy consumption significantly and higher in each cycle (i.e. descending and ascending) of the same VBS in standalone mode being operated with either propeller or thruster for sixty meters depth of operation. Our results conclude and demonstrate that the designed VBS is effective in changing the buoyancy and controlling the heave velocity efficiently and this serves the purpose of higher endurance and better performances desired in rescue/attack operations related to the UVs both in civilian and defense domains.

Car Accident

A car accident while parking the car is caused by the car driver, who is invisible around the car. However, there are no solutions for parking assistance when the driver is outside the car. The objective of this paper is to propose a reconfigurable embedded system design by voice controlled parking assistance system for a prototype electric vehicle connected to a smartphone via Bluetooth. Hardware and software co-design using the Xilinx VIVADO as a software design tool is introduced. We design the hardware and software on an ARM multicore processor and the reconfigurable system board model ZYBO: XC7Z010 by considering it as hardware accelerator. The hardware of the proposed voice controlled exterior car parking assistance system is installed on the miniature electric vehicle. The experiments are tested successfully at the parking area for both reverse parking and reverse parallel parking. This proposed system is better suited for users so that they can control their car comfortably while parking safely.

Future Work

There has been a significant amount of research investigating the design task of concept analysis, and much research on reconfigurable system design. Despite previous efforts, further research is still needed that explores how concept analysis should best be conducted for reconfigurable systems. Because reconfigurable systems have multiple configurations and different performance levels, additional information is required to understand each concept, making the design selection process more demanding. Desirable functions, concepts for each phase, and concepts for transition methods between configurations all need to be evaluated. In this paper, the fundamental challenges of reconfigurable system analysis are identified. A framework is then developed to evaluate the many options a designer may face when performing the concept analysis phase of reconfigurable system design, identifying the influence of reconfigurable systems on the process. A mini unmanned aerial vehicle case study is used to demonstrate how the framework is applied, and how existing concept analysis tools can be adapted to account for additional criteria. The paper concludes with a review of the contributions of this work and identifies areas of future work.
