How does the castle clock work?
The Castle Clock is a sophisticated version of the classical water clock or clepsydra where time is measured by the regulated flow of out a vessel where the amount is then measured. The difficulty is that the water flow rate is not uniform and depends on pressure (altitude) of the water in the vessel.
How did the elephant clock work?
In the process of sinking, the bowl pulls a string attached to a see-saw mechanism in the tower on top of the elephant. This releases a ball that drops into the mouth of a serpent, causing the serpent to tip forward, which pulls the sunken bowl out of the water via strings.
How long did Al-Jazari take to construct the castle clock?
A faithful reproduction of Al-Jazari’s enormous water clock. Built over five months to exacting diagrams in an original 13th century manuscript, the elaborate elephant-shaped water clock at the Ibn Battuta mall in Dubai is a tribute to 800 year old engineering brilliance.
When did Al-Jazari invent the elephant clock?
At the end of the twelfth century, about a thousand years ago, Al-Jazari invented a complicated clock, using forms and signs that expressed the diversity of cultures as well as the global nature of Islam, when the Islamic world was stretching from Spain to Central Asia at that time.
What is Al-Jazari best known for?
Al-Jazari built automated moving peacocks driven by hydropower. He also invented the earliest known automatic gates, which were driven by hydropower, created automatic doors as part of one of his elaborate water clocks, and invented water wheels with cams on their axle used to operate automata.
What is Ismail Al-Jazari known for?
Al-Jazari is not only known as the “father of robotics” he also documented 50 mechanical inventions (along with construction drawings) and is considered to be the “father of modern day engineering.” The inventions he mentions in his book include the crank mechanism, connecting rod, programmable automaton, humanoid …

Why was the elephant clock important?
What was Al-Jazari influenced by?
Citing the Byzantine siphon used for discharging Greek fire as an inspiration, al-Jazari went on to describe his version of suction pipes, suction pump, double-action pump, and made early uses of valves and a crankshaft-connecting rod mechanism, when he developed a twin-cylinder reciprocating piston suction pump.
Who invented clock?
Though various locksmiths and different people from different communities invented different methods for calculating time, it was Peter Henlein, a locksmith from Nuremburg, Germany, who is credited with the invention of modern-day clock and the originator of entire clock making industry that we have today.
Who is father of robotics?
How did Al-Jazari make the castle clock?
Through a process of trial and error, al-Jazari perfected his design for the castle clock. To adjust the clock, the user would simply have to rotate the regulator so that the onyx would be in the position of the required division. The position of the onyx determines the hydraulic gradient of the flow out of the chamber.
Which is the first machine described by Al-Jazari?
The first machine described by al-Jazari in his famous treatise of mechanics Al-Jami‘ bayn al-‘ilm wa ‘l-‘amal al-nafi‘ fi sina‘at al-hiyal (A Compendium on the Theory and Useful Practice of the Mechanical Arts) is a monumental water clock known as the castle clock. 1. Introduction 2. Clock’s Appearance 3.
How does the castle clock work in ingenious?
The Castle Clock had a complicated movement throughout the day, and it is on the boundary between a clock and an automaton (a machine that performs a function according to a predetermined set of instructions). There is something theatrical in many automata.
Where is the Golden Crescent on the castle clock?
The clock by al-Jazari is also very theatrical. The Castle Clock from a dispersed copy, 1315. At the beginning of the day all twenty-four doors, in two rows, are closed and the Golden Crescent, which is a little hard to see in the picture, is positioned to the left.
