Multirotors areproviding ease for various applications like, environmental monitoring, surveillance, spying, radiation data collection, indoor 3-D mapping and navigation etc. This paper introduces a design of multirotor which can reconfigure its size in-flight i.e. inflight re-configurable system (IRCS).The size can be changed by decreasing or increasing its arm length, using Rack and Pinion Type...
Continuous and accurate fluid delivery is a real challenge in many of the modern industrial applications such as continuous subcutaneous infusion, micro fluidics, delivery of hydrogel in rapid 3D printing, liquid-liquid micro extraction, etc. In most of the drug delivery systems, drug needs to be injected at a rate even less than a drop per minute. So in order to design such a precise delivery system...
Our recent work on Wave Energy Converters (WEC) introduced the ideas of a Linear Sliding WEC (LS-WEC) and an electromechanical spring, or eSpring, to dynamically control system forces and maintain resonance conditions during changing wave conditions. In that work, we assumed that the LS-WEC contained a sliding translator mass that moved on a linear track in response to buoy pitch and roll in a dynamic...

We propose a Linear Sliding Wave Energy Converter (LS-WEC) to power ocean buoys by wave energy harvesting. The concept involves a linear translator and a rotary generator that roll and pitch in ocean waves. The translator is a steel mass that is supported by wheels on rails with low-friction bearings. The translator linear motion is converted to rotary motion to spin an electric generator using a...
We propose two methods to power autonomous ocean buoys by wave energy harvesting in deep ocean environments. Both concept include a linear sliding wave energy converter (LS-WEC), which consists of a translator and a rotary generator that works on angular motions, such as rolling and pitching due to ocean waves. The translator is a steel rod supported by wheels on rails with low-friction bearings....
The steer-by-wire system in a passenger car used to enhance vehicle steering has been undergoing worldwide development. A new electronic rack and pinion steering system (SBW) along with Electronic Control Unit (ECU) is developed in this paper by using 1 DC motor and 2 sensors. A Hardware-in-the-loop steering system test rig which DC motor is attached into actual rack and pinion steering has been set...
Automobile brake by wire system has become a promising vehicle braking control scheme and enhancing braking performance over conventional hydraulic system. But these brakes require high power to generate actuation force and also problem of clogging is faced. This paper presents a novel methodology to improve braking quality and to tackle the problem of brake by wire system by introducing hybrid braking...
Vehicle handling behavior is much influenced by the performance of steering system and its mechanism. Steering linkage play a very important role in maneuvering of a vehicle. In this paper, a set of kinematic relations of rack and pinion steering linkage system are modeled in MATLAB Simulink environment based on kinematic model equations is presented to study the relationship between steering wheel...
