Experimental investigation of parabolic trough solar collector

Energy is one of the building blocks of modern society. The growth of the modern society has been fueled by cheap, abundant energy resources. Solar energy is a form of renewable energy which is available abundantly and collected unreservedly. In this research the application of solar energy using parabolic trough is analyzed. Parabolic trough technology is currently the most extended solar system for electricity production or steam generation for industrial processes. The prototype of the parabolic trough concentrating solar is collector manufactured using the available materials. The research work elaborates in detail the steps undertaken in the fabrication of the parabolic trough and other accessory parts used in the experimental setup. An experimental setup has been developed to investigate the performance of the parabolic trough. Measurements of total direct radiation on the plane of the collector, ambient temperature, wind speed, water flow rate, inlet and outlet temperatures…

Robotic Wrist Force Sensor

With the pressing need for increased productivity and delivery of end products of uniform quality, industries have been focusing on robots to perform variety of manufacturing functions in a more flexible working environment and at lower production cost. The usage of robots to circumvent complicated problems and to provide high accuracy is also vastly expanding in many areas such as in medical, aerospace, agriculture, military etc. However, since industries are shifting to a new trend of flexible manufacturing system where robots deal with multiple product manufacturing and varied complex tasks, the degree of freedom (dof) of the robot has significant contribution. For a robot of same type having different number of dof, the cost difference is quite high. Furthermore, the availability of robotic wrist force sensor (wfs) is limited to specific applications only. Hence, the improvement of the dof allows the robot to expand its application sphere and the presence of general-purpose…
