Single wheel bowling machine

In cricket, a bowling machine is a device which enables a batsman to practice (usually in the nets) and to hone specific skills through repetition of the ball being bowled at a certain length, line, and speed. It can also be used when there is no-one available to bowl, or no one of the desired style or standard.

There are a number of different types of bowling machine available to cricket coaches, each quite different in the ways they achieve the required delivery, though most allow the use of remote control so that a coach can be closer to a batsman when the stroke is played. The main mechanism of the machine consists of two heavy wheels, between 30 and 50 cm in diameter, fitted with solid or pneumatic rubber tires, each driven by its own electric motor. These are mounted in a frame such that the wheels are in the same plane, about 7 cm apart (slightly less than the diameter of a cricket ball). A ball joint allows the machine a wide range of movement. The whole assembly is mounted on a sturdy tripod or other frames so that the plane of the wheels is roughly at the height that a typical bowler would release the ball. A chute delivers the ball between the wheels, protecting the coach’s hands. It is either AC powered or DC powered.

Tilting suspension three wheel drive

A three wheeled vehicle, with two steerable front wheels and a driven rear wheel which may be either rider- or motor powered, includes steering/coupling linkage disposed of adjacent to the lower end of a steering column having a handle bar attached to its upper end. A three wheeled vehicle, with two steerable front wheels and a driven rear wheel which may be either rider- or motor-powdered, includes steering/coupling linkage disposed of adjacent to the lower end of a steering column having a handlebar attached to its upper end. The steering/coupling linkage pivotally couples a forward frame to a rear frame which supports the rider and includes the rear wheel and its means of propulsion. The steering/coupling linkage includes a pivot shaft, a bearing housing and a mechanical connection for learning the rear frame in the direction of a turn so as to compensate for centrifugal force encountered in turning the vehicle. The mechanical connection causes the rear frame to lean in a controlled relationship to the amount of rotation of the steering shaft, within rotational limits, to emulate the leaning action of a conventional bike when making a turn.

Compressed air engine four wheeler

The fossil fuel engines which were good enough for us before 30-40 years but now they are one of the sources of a contributor to global warming and pollution with fossil fuel crises. The Air Powered Vehicle is an eco-friendly vehicle which works on compressed air. An Air Powered vehicle uses air as a fuel. An Air Powered Vehicle uses the expansion of compressed air to drive the pistons of an engine. An Air Driven Engine is a pneumatic actuator that creates useful work by expanding compressed air. There is no mixing of fuel with air as there is no combustion.

Port Container Crane

Earthquakes pose a significant threat to seaports in the United States and around the World. Container cranes used to load and unload goods, represent one of the most vulnerable components of ports. Cranes are critical to the economy and post disaster response of a region. In order to better understand how cranes behave under earthquake loading, shake table experiments are conducted on a 1:10 scale model of a typical container crane found on the west coast of the USA. During previous earthquakes, three failure modes have been observed: derailment, local buckling of the legs and collapse. To investigate the various failure modes, a 1:10 scale model is constructed and tested on the six-degree-of-freedom shake table at the University at Buffalo. For ease of testing, the model is simplified by modifying the boom structure, while still preserving the most influential vibration modes. This paper presents important results from the study.

Rope Elevator

The design of motor driven household elevator chair” is a theoretical design of a hoisting system which will carry old and physically impaired people between various floors of a multistoried building. These people due to their disability can’t use the conventional staircase. The system is a modification of an elevator driven by rope and pulley in which the cabin is replaced by a chair. Thus the system will carry only one person at a time. Also as compared to conventional elevators which are used between several floors, this system is used only for one to two floors hosting. Thus the system is cheaper than the conventional elevator and can be afforded and used by individual families.

Automatic folding and sliding shutter

It is mainly used for the protection of warehouses, shops from theft. It consists of 12 blades on both sides and these blades rotate in both the clockwise and counter clockwise direction. These blades are at a 45-degree angle. Blades are made up of MS material. 2 AC motors of 1hp three phase are used. Clutch wire holds all the blades which are connected to each and every slide to prevent its free movement. There is a formation of slider and folding.

Stair Climbing Robot

For disaster mitigation as well as for urban search and rescue missions, it is often necessary to place sensors or cameras into dangerous or inaccessible areas to get better situational awareness for the rescue personnel, before they enter a possibly dangerous area. Robots are predestined to this task, but the requirements for such mobile systems are demanding. They should be quick and agile and, at the same time, be able to deal with rough terrain and even to climb stairs. This paper presents the design and implementation of a feedback control system for an RF remote-controlled stair climbing robot. The robot is controlled using PIC 16F877A.The paper presents a complete integrated control architecture and communication strategy for a system of reconfigurable robots that can climb stairs. Its mechanical design is suitable with a back wheel to drive the robot over rubble, and large wheels in the front driven by dc motor for climbing stairs. The operator can monitor the robot operation by using video that is captured by a camera on the surface of the robot. The robot system is implemented by using MikroC and visual basic programs. Experimental trials showed that the implementation of the behavior control systems was successful

Metal Bending Machine

Nowadays the world is focusing on automation. Each and every work of human is reduced by a machine, but few areas like construction the use of machines for bending rods for stirrups which are used to withstand loads in beams and columns are not done by machine because the cost of a machine is high and need skilled labors to operate it. So this project is aimed to do bending operation for stirrups using hydraulics and named as hydraulic rod bending machine. The main objective of our project is to implement the hydraulic rod bending machine in the construction sites with less cost compared to the existing bending machines, and increasing the productivity of the stirrups. Hydraulic rod bending machine consist of Double acting cylinder, P-40 Direction control valve, Hoses, Motor, Pump, Rack and Pinion, Free wheel, Fixture. The rod is bent by the hydraulic cylinder piston with holding the rod in the fixture. The main advantage of our project is the square shape of the Stirrups is bent continuously without repositioning the rod in the machine.
