Hydraulic Robotic Arm

Hydraulic systems are quite unique in themselves. At first, glance, what stands them out is the indispensable use of water, transiting through a pump to bring about fluid power. This distinct feature indicates that when such devices are seen there is bound to be a pool of steady supply of water. The water is dispensed through a set of valves on to a cylinder which converts the fluid from hydraulic energy to mechanical energy — from water to mechanical power. The system is built to allocate the hydro-induced power and relieve pressure when the need arises. The leanings behind the science of this mechanism is prescribed from the Pascal principle which recognizes that due to the incompressibility of the fluid within, the force applied to the hydro-plant, has to be unwavering, even in the event of pressure being applied at the other end. This science is commonly applicable to machinery powered by water.

The hydraulic robotic arm is a system achieved solely by the inter-relationship between machines and hydraulic systems. It is generally associated with all kinds of heavy engineering appliances powered by fluids. This could include the grappling system of a crane or a string network of a forklift. The main driving force of this equipment is powered through the hydraulic cylinder drawn from a dynamic differential equation.

Typically, the cylinder stores up the fluid needed and ends up dispensing it, with equity, adequately. This is where the definition of a hydraulic system which is the use of hydro-induced power to power up machinery, stems from. These would usually consist of three parts namely: the generator (which doubles as the hydraulic pump), driven by a combustion engine such as valves, filters, piping, etc. all enclosed to make up an electric motor, making up the actuator, to drive the arm.


As indicated earlier, the components of this machinery include an electric motor, valves, filters, piping, hydraulic pump, generator, and actuator. However, the mechanism of this device encases each part with a sizable degree of freedom to move and chart the course for others to bring ease to the movement of objects and carrying out other tasks. The entire system entails a fixed vertical link for it to be connected firmly and the horizontal link for it to be able to rotate effectively around the vertical link.

Attached to this link is the slotted type box that is also permitted to rotate around this link, which can also make the sliding motion made solely possible by the fluid. Connected to this sliding operation are attached four spoons represented as arms to pick up the objects. The whole mechanism is geared by a pinion and rack system to encourage ease among the operating system in general with a rotation of 130 degrees.


The hydraulic robotic arm is commonly summed together with a network of fluid and syringes powered by the former. It constitutes of various parts, merged into each other which are coupled in a premeditated manner in order to serve the need for the desired result.

Commonly, when this appliance is formed, the intent for its production is usually to carry out heavy tasks that would ordinarily impede the day to day relations between humans and the so-called impossible assignments. Hence, one could find these arms in the process of assembling products in factories alongside playing the mechanical role, necessary for painting a car. They are also applied by earth movers to pick up heavy weights and assign them to where they are required to be.

Safety Precautions

It is a common saying that while utilizing heavy machinery, it is important to keep safety nearby. These are also applicable when using hydraulic equipment. The safe operating procedures include the following:

Personal Protective Equipment (PPE)

While performing an operation on hydraulic systems, do not fail to wear personal protective equipment including overalls, gloves, rubber boots, etc. Also, remember to wear a set of protective goggles or any other viable eye protector as a user of hydraulic equipment runs the risk of sparks.

Lifting Safety

One should not solely rely on a hydraulic lift, like in case of a crane if one must work with hydraulic components with the equipment raised. A set of the responsive working unit should be around the area to register precautionary measures in case of an accident.

Servicing the System

If one is draining the hydraulic cylinder, it is vital not to run the machine engine when a person is servicing it.

Changing Connections

Hydraulic fluid tends to be very hot and can cause severe burns. Therefore, one should let the system to cool before touching components such as lines, connections, filters, or fittings. Before removing the cylinders, make sure they are mounted on the ground, safety stands or blocks, and the engine is shut off and use a jack or other lifting device if one needs to detach hydraulic pumps or valves.

Active Check-ups

Examine the hydraulic system for leaks and wear and coat the required components with a lubricant to prevent rust. Also, it is sacrosanct to replace filters, and keep the engine oil away from pollutants; dirt could cause big damage to the machinery.

Undue Interference

When one is done with the machine, it is important to park it beyond the reach of children or places where they would not possibly reach or come in contact with it. In addition, to keep the machine steady during transportation, one should shoot the cylinder stops.

Escaping Properties

It is a common sight to see oil escaping from hydraulic machinery. However, to reduce this, be certain that all line connections in the equipment are tight.


Utilize, when washing parts, a prescribed cleaning solution. And when in use, keep the system properly adjusted for convenient control of the machine.

Finally, the crux of life cycles requires that we carry out tasks that would extend beyond our human capacities. This evokes the need for machines. This equipment would serve, by the guidance of humans but would serve in line with how we choose to power them. The hydraulic robotic arm is one of these appliances. However, with the knowledge of the safety precautions, this machine, and its other associatesHydraulic Robotic Arm, would serve its users to their desired capacity.
