Gears in Robotics

GEARS

You have to look the information related with each of the following ideas and put it in your blog.

1. Gears in robotics: a toothed part of a machine that is held together with another toothed part used to change the speed or direction of transmitted motion.

2. Concept of Force: is one of the fundamental concepts of physics. It is something that changes the motion of an object.

3. Concept of Torque: mechanical part that changes the rotational motion of an object.

4. How gears work?

Gears are used in basically every mechanical object. They make the electronic devices work by implying a special force that makes them move. They can also modify the direction of the rotation of something. For example, when a car turns, the power from the shaft is transmitted to the wheels. This makes the wheels turn.

5. Types of gears: explain each type and have a picture of it.

There are many types of gears, some are:

• Spur gear:

• Bevel gear:

• Crown gear:

• Worm gear:

• Differential gear:

• Pinion:

• Cogwheel:

• Idler gear:

• Ratchet:

• Pawl:

• Planetary gear:

6. Gears efficiency:

7. Direction of gear rotation: a gear can rotate in two different directions, forward rotation and backward rotation. The forward rotation, also called standard rotation, is when the central part of the tooth in the gear goes in the gearing region. The backward rotation is when the tips of the teeth first go in the gearing region.

8. Gear pitch: the pitch is the space between the teeth of the gear where another gear’s teeth would fit.

I, Robot: The 3 Laws of Robotics

The one who invented the 3 Laws of Robotics was Isaac Asimov. He was born in Russia, Petrovichi, on January 2nd, 1920, and died on April 6th, 1992 in New York, USA. He was an American author and taught biochemistry at the University of Boston. He is best known for his popular science fiction works and science books. He has written over 9000 letters and postcards and edited nearly 500 books; he is considered one of the most prolific writers of all time. He was the writer of the series called I, Robot, which nowadays is very popular.

3 Laws of Robotics:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.

2. A robot must obey orders given it by human beings except where such orders would conflict with the First Law.

3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

In the movie, I, Robot, the robots must follow the three laws, but the program V.I.K.I, starts creating robots that can decide whether or not to follow the laws. These robots it creates, are a threat to humans since they don't treat them right and make them stay at their houses so that they can't interfere with V.I.K.I.'s plan to control everything. Also the protagonist, Dt. Spooner, hates robots because he had an accident and an older version of the robots saved him instead of a girl, who was also in danger, and she died.
