Types of robots

February 23rd, 2008 by bjkrobotics

Robotic arms: Robotic arms are possibly the most widely used robots in the construction industry, they can be used to pick up items, construct objects and wok in assembely lines. They can also work 24hours a day giving them a huge advantage over human workers. The main action of the robotic arm is to preform repetative tasks but also for maintinance and repair.

the Smart Crane Ammunition Transfer System: is a robot truck in development for use in the military, the main idea of the truck is that only one soidier will be required to deliver supplies to areas. The truck has a crane like contraption on the back which the soldier sitting inside the front can control to pick up the goods in the back and take them off the truck. The main action would be to preform tasks that would be dangerous for humans.

Nanobots

Basicaly nanobots are microscopic robots. The project of nanorobotics is a very important one and prodution of nanobots doesnt seem to far off. But what are nanobots you might ask well basicaly they work and preform pre-programed, remote controled or use sensors to preform tasks like all other robots exept for one majour difference, the size. The bigest aim for nanobots is in the medical industry, to work inside humans, to serve as antibodies, to repair damages tissue, fight disease, and even rebuild/repair damaged organs. Some will be pre-programed, other will use remote control but the bigest aim will be for them to use sensors and eliminated lots of hard work.

The main advantage of nanobots would be their ability to last for years and continue working efficiently. They also said to be able to work very fast this would become especialy evident and important in emergency situations. Since they are programed/contorlled and may possibly use sensors they would eliminate alot of work from doctors and make their jobs a bit easier.

One disadvantage would be that a large number of them would be required to preform these tasks. This could prove costly and would contain alot of extremely difficult manouvouring to get them to area in the body where they are needed, this would create more hard work and potentialy eliminate the advantage of less work for the doctors.

The production of nanobots would revalutionise the medical world, but alot of hard work is still needed before they may be ready to be mass produced. All the faults must be worked out and many test prototypes will be constructed. But one thing is for sure and thats is once they are completed the world of medicine will never be the same, some diseases may be whiped out and alot of lives will be saved.

Parts Of a Robot

February 23rd, 2008 by bjkrobotics

A. The 5 main parts of a robot include: The arm, the controller, the drive, the end efector and the sensor

The Arm- The arm is the part of the robot that positions the end-effector and sencors to do the job they were programed too. Most robot arms resemble human arms this gives the robot a lot of ways to position itself in its environment.

The Controler- The computer that is used to program the robot is called the controler, it alows the robots to conect to a network and work with other robots/machines.

The Drive- The engine that drives the links of the robot usualy powered by air, water pressure or elctricity.

The End Effector- The ‘hand’ conected to the end of the robot, there are many variations of end effectors, depending on what the robot is designed to do e.g hold tools, grip onto things ect.

The Sensor- The sensor alows the robot it ‘examine’ its environment, it sends info about its surroundings back to its contoling computer and determines its next movement.

B. The 6 degrees of freedom: many robots today are made to resemble human arms, usualy they have a shoulder, elbow, wrist and fingers. They are made like this to alow the robot many different movements. Robots need the 6 degrees of freedom to preform simple tasks, since each direction a joint can move provides 1 degree. the robots have 3 joints ‘the shoulder, elbow and wrist’, 3×2=6.

Historical perspective of robotics

February 23rd, 2008 by bjkrobotics

A. When was the first actual robot invented and used? The first robot to be created and programed by William Pollard and Harold Roselund, it was designed as a spray- pianting mechanism

B. The three laws of Robotics: The book writen by Isaac Asimov was called I, Robot and the 3 laws were; 1. A robot must never injure or harm a human being, or through inaction, alow them to come to harm. 2. Robots must obey all orders given to them by humans, unless the orders conflict against the 1st law. 3.Robots must protect their own existance as long as it doesnt conflict with the 1st and 2nd laws.

C. Zeroth Law: the Zeroth law states that robots must protect ALL humanity and not just individual humans. its called this becasue its before the first law (”0′th”)

D. When can a robot harm a human: The only circumsdance where a robot may harm, even kill a human is when preforming surgery. This is because the robot is trying to save the persons life and is technicaly not doing them any harm because they are sick in the first place.

Robots and Robotics

February 23rd, 2008 by bjkrobotics

Define Robot: The Maquarie dictionary defines a robot as “A mechanical self-controling apparatus designed to carry out a specific task normaly completed by humans.” . They are designed to preform tasks may be difficult for humans to complete sometimes due to hash condions, repetitiveness ect.

Define Robotics: Dictionary.com defines robotics as ” The science or study of the technology associated with the design, fabrication, theory, and application of robots.”

Purpose and use of robots.

February 23rd, 2008 by bjkrobotics

A. Industrial Robots: Programed to preform industrial tasks e.g. car assembly lines. They are programed by humans can be reprogramed and usualy preform repetative tasks.They may also preform tasks that may be difficult for humans and can work in harsh conditions.

Domestic Robots: Robots that can be used around the house e.g. the iRobot Roomba, the austomatic vacume cleaner created by iRobot corporation and the robomower, automatic lawnmower which travels up and down the laws cuttin the grass. They both use infa red technology to find their way around. Vidio of the roomba can be found at “http://www.youtube.com/watch?v=HqhIMFQNGCg.”

Entertainment robots: Entertainment robots such as the robo sapien, robo raptor, robo dog and furbies are mainly designed as toys, they preform simple activities such as walking and talking and are usualy usued by children of all ages. They may be remote control or use infa red and some respond to human activity.

B. Multi-purpose robots.

The FANUC Robot LR Mate 200iC is a great example of a multi-purpose robot, it is about the size of a human arm it is lite weight and is suitable to preform a wide varitey of tasks including machine tool handling, bin picking, assembly and insertion. It is also has a high reliability in the severe factory environment. The robot only weights 27kg so it can easily be instaled inside a machine or monted on a celing. Because of its capability to hold tools it can easily be used in maintinance and repair.
