This work discussed the fabricated model of android based grass cutter in agricultural field by implementing the new innovative concept with simpler construction and easy working. The cutting motor is employed to cut the grass in the field and the same is controlled by smartphone application. The components that are used to control the grass cutting level involve motor and gear arrangement. Below the gear arrangement, the cutting blade is fixed. And this arrangement will be simple and highly efficient for grass height adjustment system with up/down process motor. DC motor up and down motion is made using the rack and pinion gear setup. And then grass cutting motor on off control system will be achieved through android application. This application is connected to the Bluetooth communication for automatic the process. This work is motivated on preparation of the beneficial power basis for grass cutting process which is not reliant on the climates state and also prompt on its work. This setup is completely controlled using smart phone. In future, the automation of the device will play the most important role in world wide. In the meantime, technologies are merging with environmental awareness, consumers are looking for ways to contribute to the relief of their own carbon footprints.
A universal gripper is a component that consists of fine dust material enclosed in fine rubbery membrane for holding and assembly. The gripper is especially applied for quickly gripping and discharging large number of objects having complex geometries in wide applications. The objects which are in various shapes and different geometries are difficult to grasp which confirms that it is not suitable for apply in various pick and place operations. In this project, a low cost modular gripper is implemented with suitable mechanical design, structural analysis and real time analysis. In this association, the designed gripper can hold many parts and place it at once while sustaining relative distance and relative coordination at their state. The universal gripper acts as a vacuum tube to grip the object it needs to relocate. This universal gripper can hold various objects such as eggs, grocery items, industrial components, heavy objects etc., therefore, a selected experimental setup has been developed with the composition of shapeless gripper and perform simulation in holding of the different items. Results of the tests and experiments shows the proposed Universal Gripper are validated with feasibility options.
In this paper, an innovative design model of autonomous aerial vehicle is designed and fabricated with dual rotor setup. Nowadays, innovative unmanned aerial vehicles (UAVs) are widely required for surveillance, monitoring, data collection, reconnaissance and generally in places where humans face hazardous. In this model and design of UAVs, aero dynamic principles are adopted through reasonable design considerations and assumptions. Most of the researchers and academicians are currently pursuing research on AVs with various structures, wing designs, fabrication methods, controllers and materials to increase the efficeincy as well as for various applications. In this proposed work, an effort is made to design and fabricate the dual copter with wide moving ranges for surveillance applications in military intelligence system. This proposed design will be suited for all environmental conditions to collect the data as well as monitoring the system. Dual copter chassis are fabricated using 3D printer after the validation and analysis the proposed design using Solidworks CAD tool. The chassis are fabricated with the provision of space where the required sensors, actuators and controllers can be assembled. Lithium polymer batteries are employed to achieve the better performance for copter. The fabricated setup is integrated with radio frequency controller to achieve the flight control through RF transmitter. Hence the performance of the fabricated device is validated and analyzed through various performance measures of dual copter.
