robot kinematics‚ require a unified methodology to identify the variables of a robot’s or manipulator’s joints and links. Co-ordinate Frames Robotic kinematics depends on the use of right handed cartesian frames of reference. Manipulator Geometry A manipulator consists of two types of joints‚ connected by a link. Link A link is a solid mechanical structure which connects two joints. The main purpose of a link is to maintain a fixed relationship between the joints at its ends. The

Descriptive Geometry “Drawing is the language of design‚ and if drawing can be thought of as a language then‚ descriptive geometry is the grammar of this language.” Definition: Descriptive geometry is the branch of geometry which allows the representation of three-dimensional objects in two dimensions‚ by using a specific set of procedures. The resulting techniques are important for engineering‚ architecture‚ design and in art. The theoretical basis for descriptive geometry is provided

TIMELINE OF GEOMETRY It is believed that geometry first came to being when and Egyptian Pharaoh wanted to tax farmers who raised crops near the Nile River. To do that the pharaoh’s agents had to measure the amount of land that was being used. 1. 2900 BC – The first pyramid was constructed. The knowledge of geometry was important due to the fact it consisted a square base and triangular faces. 2. 2000 BC- It was the earliest record of calculating the area of a triangle‚ however there is

Geometry Rationale Geometry is Greek for geos‚ which means Earth‚ and metron meaning measure. It can conceivably lay claim to being the oldest branch of mathematics outside arithmetic‚ and humanity has probably used geometrical techniques since before the dawn of recorded history. Initially‚ as with the Egyptians‚ geometry originated from practical necessity and the need to measure land. Geometry today is the science of observing and measuring shapes‚ surfaces‚ angles‚ lines and the relationships

Reflective Paper MTH/157 Throughout this math course‚ there were many different strategies that were taught. Many that I‚ in particular‚ was very unfamiliar with. As I am planning on teacher early elementary‚ I am hoping that I do not have to teach too many of these new strategies. Some of them were very difficult and somewhat complex‚ and some of them were a review from previous classes. During this course‚ there were several major mathematical concepts that were taught and reviewed. In chapter

Circles Introduction "Geometry‚" meaning "measuring the earth‚" is the branch of math that has to do with spatial relationships. In other words‚ geometry is a type of math used to measure things that are impossible to measure with devices. For example‚ no one has been able take a tape measure around the earth‚ yet we are pretty confident

Euclidean Geometry Geometry was thoroughly organized in about 300 BC‚ when the Greek mathematician Euclid gathered what was known at the time‚ added original work of his own‚ and arranged 465 propositions into 13 books‚ called ’Elements’. The books covered not only plane and solid geometry but also much of what is now known as algebra‚ trigonometry‚ and advanced arithmetic. Through the ages‚ the propositions have been rearranged‚ and many of the proofs are different‚ but the basic idea presented

Geometry has many uses. It is used whenever we ask questions about the size‚ shape‚ volume‚ or position of an object Geometry is the foundation of physical mathematics present around us. A room‚ a car‚ anything with physical constraints is geometrically formed. Geometry allows us to accurately calculate physical spaces and we can apply this to the convenience of mankind. . The geometry is heavily used in drawings‚ carpeting‚ sewing‚ architecture‚ art‚ mathematics‚ measurements‚ sculptures etc.
