What is Flexible Automation?

Refers to machinery that is capable of performing a variety of tasks

What are some negative aspects of having robots as part of the workforce?

Workers and members of labor could be replaced by robots.

What are some positive aspects of having robots as part of the workforce?

Robots are more productive at some tasks than humans

Pick-and-place motion: Programming this pattern of motion is done by manually setting mechanical end stops or limit switches for each designated point. Because of the laborious programming, the number of points the robot can move through is comparatively low

Continuous-path motion:

This method is an extension of point-to-point motion. It can involve several thousand points, resulting in movement that is smooth and continuous. Control of the end effector’s path is more important than end point positioning.

Point-to-point motion: Programming involves moving the robot through a number of points in space. The programmer uses a combination of manipulator axes to position the end effector at a desired spot. The path of motion is a series of straight lines between the points.

What is command resolution?

Is the closest distance between movements of a robot. It is calculated by dividing the travel distance of each joint by the number of control increments.

What is spatial resolution?

Describes the accuracy of movement of the robot tool tip. It takes into account command resolution and mechanical inaccuracy.

What is the purpose of the controller?

Is a microprocessor linked to input/output and monitoring devices. It coordinates all movements of the mechanical system. It also receives input from the immediate environment through various monitoring devices.

What is the purpose of the manipulator?

Is the arm of the robot that is used to move materials, parts, tools, or special devices through various motions to provide useful work.

What is the purpose of the end effector?

Is a device attached to the wrist of the manipulator for the purpose of grasping, lifting, transporting, maneuvering, or performing operations on a work piece.

What is the purpose of the power supply?

Is a mechanism that provides the energy to drive the controller and actuators.

What is the purpose of a means for programming?

Is used to record instructions that are saved to the controller. A robot may be programmed using any of several different methods, one of which is by using a teach pendant.

Programming for robots First generation period: Late 1950s through the mid-1970s. Performed purely repetitive tasks and did not respond to changing conditions. They had only 2 or 3 degrees of freedom. Used pneumatic or hydraulic actuators. Pneumatic or electric relay logic circuits were also commonly used. Computer-controlled manipulators were introduced.

Programming for robots second generation period: Mid 1970s through the mid-1980s. Manufacturers introduced robots that could be controlled by means of programming language. Robots were equipped with internal sensors and closed-loop control systems. Sensors gave them a limited amount of feedback about their environment and condition.
