Problem

Intro:

  Have you ever seen a car lifted into the air at an auto repair place? Have you ever wondered how an elevator can lift a load of people up into the air? Well, the answer is hydraulic systems. Hydraulic systems use a liquid, usually oil, to transmit force. This system works on the same principles as other mechanical systems and trades force for distance. Hydraulic systems are used on construction sites and in elevators. They help users perform tasks that they would not have the strength to do without the help of hydraulic machinery. They are able to perform tasks that involve large amounts of weight with seemingly little effort. This work illustrates a simple approach to demonstrate the principle of hydraulic power by manufacturing and operating a robotic model from simple and recycled materials.Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering project, you will get a firsthand look at the power of a hydraulic system by building your own working model of a lift. 




Question/Purpose/problem:

I did my project because I wanted to see and learn how people make cranes and since we had been learning about hydraulics in our other unit I found hydralices really interesting. So I decided to do more research and it led me to making my science fair about how people make lifting cranes. 
Q: How does a Hydraulic Powered Robotic Lift Crane work, and how can we  use this technology in our everyday life?
I tried to research a way on how to make a lifting crane I have seen lifting cranes before but I wanted to make a new model of a lifting crane. 
- We can use a hydraulic lift in real life for many things, because they are very strong and can lift up very heavy things. As an example lifting cranes can be used to lift up whales when they are stuck at the beach. But the main porpose was to find a way to help the environment!

Q: How does a Hydraulic Powered Robotic Lift Crane work, and how can we use this technology in our everyday life? pressurized hydraulic fluid pushes the piston in and out of the cylinder, allowing the piston to lift or move a load. With hydraulic systems in cranes, there are typically two different pistons. When one piston is compressed, the displaced oil forces the other piston to extend. We can use this in our everyday lives by A hydraulic crane is a type of heavy-duty equipment used for lifting and hoisting. Unlike smaller cranes, which rely on electric or diesel-powered motors, hydraulic cranes include an internal hydraulic system that allows the crane to lift heavier loads. Ex: lifting a whale of the beach 


Analyze / Observation
When you push on the plunger of the movable syringe, the arm rises; when you pull on the plunger, the arm descends.Pushing on the plunger applies pressure on the water in the movable syringe. Since the water is confined and incompressible, Pascal’s principle comes into play, telling us that the pressure is transmitted undiminished to all parts of the water and to the walls of its container. Since the plunger of the fixed syringe at the other end of the tube forms part of the “container” for the water, and is the only part of the container that can expand, the pressure causes the plunger in the fixed syringe to move.In the right-side-up position, the plunger pushes on the arm to raise it. But when you turn the whole assembly upside down, the syringe pulls on the arm to raise it, just like your muscles do with your own arms.The muscle that allows your forearm to lift things, called the biceps, is attached near your shoulder and just below your elbow. When the biceps contracts, it has the same effect on your arm as the syringe has on the hydraulic arm when the assembly is upside down. The muscle that allows your forearm to lift things, called the biceps, is attached near your shoulder and just below your elbow. When the biceps contracts, it has the same effect on your arm as the syringe has on the hydraulic arm when the assembly is upside down. In both cases, a large force is exerted so that a small weight can be lifted, but the weight can be lifted a large distance compared to the distance the force moves (the distance the syringe plunger moves, or the distance your muscles contract). Hydraulic systems are used in countless applications: brakes and steering on cars,hydraulic lifts and jacks for servicing cars,airplane wing flaps,stabilizer controls, and landing gear, mechanical arms on garbage trucks; blades on bulldozers,and so on.

Purpose

We can use a hydraulic lift in real life for many things, because they are very strong and can lift up very heavy things. As an example lifting cranes can be used to lift up whales when they are stuck at the beach. The lifting Crane is a machine that operates in our daily lives. As we use a crane, it helps us create buildings and lift building material to a certain designated area. A lifting crane is a machine that is used to lift and move heavy loads, machines, materials, and goods for a variety of purposes. They are used in all different sectors of industry, from construction to manufacturing to shipbuilding and material loading. They are used for heavy loads and can last long.A hydraulic crane is a type of heavy-duty equipment used for lifting and hoisting. Unlike smaller cranes, which rely on electric or diesel-powered motors, hydraulic cranes include an internal hydraulic system that allows the crane to lift heavier loads. 

  

Result 
When you push on the plunger of the movable syringe, the arm rises; when you pull on the plunger, the arm descends.Pushing on the plunger applies pressure on the water in the movable syringe. Since the water is confined and incompressible, Pascal’s principle comes into play, telling us that the pressure is transmitted undiminished to all parts of the water and to the walls of its container. Since the plunger of the fixed syringe at the other end of the tube forms part of the “container” for the water, and is the only part of the container that can expand, the pressure causes the plunger in the fixed syringe to move.So that hw my crane was able to move up and down, and let go and pick things up!

Conclusion

CONCLUSION my design uses extremely simple ideas and mechanisms to achieve a complex set of actions and is intended to imitate the action of the operators. However, these hydraulic arms are expensive for small scale industries. If the major problem of high initial cost is addressed, a robotic hydraulic arm can be introducing in any industry to bring in automation. The mechanical links and parts that have been fabricated are extremely simple. The prepared mechanism has been successfully constrained and executed to carry out the required work of picking up the weight of the object like table tennis ball and to put them in to the placed at different location. The Hydraulic Arm Will-  Reach the greatest distance to deliver a given object.  Pick up the heaviest possible object.  Deliver the most objects in a given amount of time.  Function in an assembly line.  Have a system to weight the object it picks up. Battle against another arm of an object.  Rotate as well as reach and grab.  Dig and recover objects. So, we are confident that the people will understand and join us on the quest to make our planet a pollution free place to live in. FUTURE SCOPE If more time and more efforts would have been put into the model, more complexities could have been brought out. Moreover instead of manual operation of syringes could have been replaced by predefined computer programs or merely by pressing the switch operated. Further, more varieties and more flexibility to add or replace any part according to requirements can be done to improve its use and increase field of usage and to make it more universal or flexible. As we know that the natural source of fuel is decreasing day by day, we need to remove our dependency on these sources with an alternative resource.

We have to use some of alternative Energies like Solar Energy, in our vehicle. Hydraulic crane helps to increase the speed of work. We can do a lot of work is no time using this equipment. Hence as a result our work completes faster.
This machine helps us to make our work easier. We can easily lift heavy loads using less effort.
Initially there used to be necessary of many peoples. After using this hydraulic system lots of work is done using few crew members.
Since working crew are decreased, this proportionally decrease the cost of work. Which is good for companies.

1.The  design  of the present  model is easy and simple  for manufacturing and implementation. 
2. Low-cost  and  even  recycling  materials  can be  used  to produce this model. 
3. Due to its small size and weight, this model can be used anywhere. 
4. This  model  is  an  effective  and  simple  tool to  educate the concept of hydraulic power to engineering students.

How does it work? The hydraulic lifting crane is based on a very simple concept, it is based on the transmission of a liquid from one point to another. Some machines use a fluid that does not let any blank space inside the tube,which helps in the management of the hoist. Oil is the liquid which is more often used. In the crane all energy is in the oil when the oil pressed down it gives energy to a piston which makes it move, In the simple system. When a power is pushed down another is pushed up making it move. Pressure creates movement for the pistons so that they can move the crane for different positions. The muscle that allows your forearm to lift things, called the biceps, is attached near your shoulder and just below your elbow. When the biceps contracts, it has the same effect on your arm as the syringe has on the hydraulic arm.For this project we consider as a hypothesis that by a flux of water, we will use the hydraulic pressure to lift or increase some force.the hydraulic crane is based on a simple concept: the transmission of forces from point to point through a fluid in a simple hydraulic system when a piston pushes down on a fluid like oil, the oil transmits all of the original force to another piston, which is driven up most hydraulic cranes use two-gear pumps that have a pair of intermeshing gears to pressurize the hydraulic oil. When pressure needs to increase, the operator pushes the foot throttle to run the pump faster. In a gear pump, the only way to get high pressure is to run the engine at full power.
