The objective of the project is to make an assistive limb to assist human beings in some or other activity, eliminating human errors and increasing productivity. The most common activity humans perform, be it a soldier or an industrial worker or a rural woman, is weight lifting and that is what we aim to target. The idea is to make an exoskeleton which will help human beings lift heavy weights without feeling any load/stress on the human muscle. The prototype made when worn by a human can successfully lift up to additional 40kgs with the one arm.
The exoskeleton is ...

The purpose of this project is to propose a new propeller-type climbing robot for climbing various types of structures which include significant obstacles, besides inspection of industrial vessels made of various materials, including non-ferromagnetic material. The inspection process includes capturing images of important spots which are prone to corrosion, as well as measuring the vessels' wall thickness.
The design mainly consists of two coaxial upturned propellers mounted on a mobile platform with four standard wheels. A new hybrid actuation system that consists of propeller thrust forces and standard wheel torques is considered as the adhesion system for this climbing ...

ROLE OF OUR MACHINE:
The high amount of labor necessary for weeding, harvesting, drying, threshing and shelling makes the crop economically unattractive to the younger generation of farmers. The very laborious tasks of threshing and shelling are made easier with our groundnut separator and decorticator machine. The areas where our machine sounds helpful are as follows:
INSIGHT OF THE MACHINE:
A rectangular frame is made with 5mm thick mild steel with a total height of 4 1/2 feet to which two cross bars are welded throughout the length. To the first cross bar, a shaft of ...

In a conventional Reciprocating Compressor there are a number of moving parts like the crank, connecting rod, belt drive system, and electric motor which contribute in frictional (mechanical) losses resulting in low efficiency. Also it is bulky in size and high maintenance required as it consists of motor, belt drive system, rotating parts. The capital and running cost of this type of compressor is high. All above disadvantages are overcome by an electromagnetic reciprocating air compressor. It works on the principle of electromagnetism. In this type of compressor almost all moving parts like the motor, belt drive system, crank, ...
To provide the high security for houses and confidential places by capturing a photograph and sending this photograph to the android app (which is made by us). As no one in the house, security of a house is a big challenge moreover in the private labs where some confidential work has been done, supposed to be secure by anyhow.In this, the camera is attached with the doorbell. We have a switch inside the house for “on” or “off” the system. If we are doing the system “on” So, the system will capture image of all the persons who ringing ...
In the past decade, robotic systems have been used with increased popularity for explosive ordnance (EOD) missions. Advances in robotic technology have made it possible for robots to perform functions previously only possible by human workers wearing a blast suit. The primary advantage of using robotic systems for explosive ordinance disposal/diffusion is reduced risk to humans. The bomb diffusing robot which will help to improve defence of our nation from terrorist, suicide bombers and other such activities. The bomb detectors and disposal system works only with the presence of experts. But this way of analyzing takes more time and ...

One of the most commonly employed technologies of additive manufacturing is fused deposition modeling (FDM). FDM that employs polymer as the based material has proven to be a powerful method in rapid prototyping. Most of the FDM 3D printer feed stock material is Polylactic Acid (PLA), Acrylonitrile-Butadiene-Styrene (ABS), Nylon and etc. These limited choices of material for FDM printing had limited the option for engineers to create an object with a blend of different materials to create something unique where the object is being optimized not only in terms of shape but also the used of different materials to ...
The proposed approach present the development of a computer tool that allows, in the first phase, the modeling of the electric vehicle power chain. This phase is based on a library developed under the Matlab-Simulink simulation environment. This library contains all the components of the power chain; it offers the selection of the desired configuration of each component. In the second phase, the tool solves the autonomy optimization problem. This problem is resolved by a program based on genetic algorithms. This program permits to optimize the configuration parameters maximizing the vehicle autonomy of the chosen chain. This tool is ...

Background: Over tightening of screws is common and results in damage to the screw’s thread.
I have developed a method which determines the optimal point in time to stop tightening the screw. The advantage over existing methods is that my method doesn’t require torque and rotation sensors and is therefore cheaper and easier to integrate into existing power tools.
The method on which the suggested invention is based happens to be well known in the field of mechanical engineering and is commonly termed "Yield Controlled Tightening" or "Torque to Yield." The method is best described by Figure 2 ...

Gear and Teeth for On-site Repair (GATOR)
Plastic Gears and Additive Manufacturing Background
Gears are among the most important and commonly used elements across a range of mechanical applications. Recently, composite plastic gearing has seen an increase in usage for a variety of applications because of its low cost, weight, and its ability to satisfy mechanical requirements of gearbox or power transmissions. During gear use, large forces are produced at the base of the gear teeth, resulting in wear and degradation. In fact, more than 85% of gear failures are associated directly with teeth disintegration. Because plastic gears are currently ...
