Manufacturing robots are known for their speed, accuracy, and efficiency. These qualities make them a popular choice for part production lines throughout the world. Not only do manufacturing robots lower costs and increase productivity, but they can be integrated for a wide variety of applications. Robots are responsible for the success of many commercial manufacturing companies. There are many benefits to integrating robotic equipment. Manufacturing robots bring about faster, more efficient production. The chief advantages of switching to manufacturing automation are cost cuts and quality increases. RobotWorx team of expert technicians and engineer's custom build manufacturing robotic systems for commercial facilities throughout North America.
According to the Robot Institute of America (1979) a robot is:
"A reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks".
A more inspiring definition can be found in Webster. According to Webster a robot is:
"An automatic device that performs functions normally ascribed to humans or a machine in the form of a human".
A Brief Description
With a footprint not much larger than a piece of A4 paper and a working area of 200 x 200mm, the smallest machines still have all the functionality of their larger brethren. Bigger versions cover 800 x 600mm with a Z-axis of 200mm. They are often self-contained, controlled by internal computers.
Typically, programming is by means of a teach pendant, using simple step-by-step instructions. Program inputs are prompted. Programs are stored on the machine or, optionally, can be kept off the machine on a PC. Software can be generic, allowing full control of all functionality by the programmer, or function specific (e.g. dispensing), where the software is customized and even more user-friendly. Point-to-point and continuous path motion are selectable. Whilst 2-axis machines are available, 3-axis are the most popular, with full interpolation of lines, arcs and circles through all three axes. A fourth, rotational axis is used for more complex, non-planar jobs. Positional accuracy is within fractions of millimeters (0.01mm is typical), and movement speeds can reach one meter per second. There are inputs and outputs which allow an interface with external devices (e.g. pick and place pneumatics). They may be driven by servo or stepper motors, with belt or ball screw drives.
With a decade of installed units to reference, this category of machines has shown remarkable reliability. Maintenance is relatively simple, and they are built robustly and fit for shop floor use. They may incorporate self diagnostic procedures in case of malfunctions.
There are three major types of small robot:
