Robotics is one of the young fields of modern technology that has crossed the limits of traditional engineering.[1] Understanding of robots requires knowledge from a very vast domain including mechanical engineering, electrical engineering, systems and industrial engineering, economics, computer science and mathematics. Manufacturing engineering, knowledge engineering and applications engineering are some of the new fields which are emerging rapidly to deal with the complexity of robotics and industrial automation.
[2]A precise official definition of a robot comes from the Robot Institute of America (RIA):
A robot is a reprogrammable multifunctional manipulator designed to move material, parts, tools, or specialized devices through variable …show more content…
Hydraulic actuators are unrivaled in its response speed and torque producing capacity. Therefore hydraulic robots are mainly used for heavy lifting. There are many disadvantages of hydraulic robots like leakage of hydraulic fluid, requirement of much more peripheral equipment such as pumps, which in turn requires more maintenance and production of noise. Robots powered by DC or AC servo are becoming popular because they are much cheaper, cleaner and produce less noise. Pneumatic robots are also inexpensive and simple, but controlling them is an issue. As a result, pneumatic robots are not so popular.
Assembly is the largest projected area of robotic applications. Therefore, robots are often classified into assembly robots and non-assembly depending upon their application. Assembly robots are small, electrically controlled and driven and either revolute or SCARA.
Most industrial manipulators currently have six or fewer degrees of freedom. [] These manipulators are generally classified kinematically based on the first three joints of the arm, while describing wrist separately. Most of these manipulators fall into following five geometric types: articulated (RRR), SCARA (RRP), spherical (PVP), cylindrical (RPP) or Cartesian (PPP).
A robot manipulator should be seen as something more than a series of mechanical connections.
