The global manufacturing industry has embraced the latest technological advancements in robotics and automation. Manufacturers around the world now use industrial robots to execute tasks with high precision, increase output, ensure worker safety, and reduce operating expenses.
Indeed, the adoption of robotics technology can provide a lot of advantages to the manufacturing sector. But what are the types of industrial robots that are being used nowadays? Here’s an article to answer that question.
Delta robots have been around for many years since its invention in the 1980s. These spider-like robots are fast workers, thanks to the precise, high-speed movements of their three parallel arms with unique end effectors.
Delta robots are ideal for fast product transfer applications. For instance, they are used in the electronics industry to pick electronic parts from one conveyor belt to another. Industries such as pharmaceutical, food, and electronics use delta robots to boost production and packaging output.
The configuration and mechanical movement of articulated robots have in common with how the human arm work. This type of robot is typically mounted on a base with a rotary joint. Articulated robots can range from simple two-jointed structures to complex structures with ten rotary joints.
Each of the joint of these robots is specifically designed to allow a greater degree of motion. In the manufacturing sector, you can find articulated robots with four or six joints, the most common ones. They can help in typical applications such as material handling, arc welding, assembly, packaging, and machine tending.
Named after the widely celebrated French mathematician Rene Descartes, cartesian robots are standard devices used by manufacturers today. They function on three linear axes that utilize the Cartesian Coordinate system (X, Y, and Z). Their linear movements are in and out, up and down, and side to side.
Cartesian robots are easy to configure and highly flexible when it comes to their application. Users can easily adjust their size, speed, stroke length, and precision, depending on the work at hand. These industrial robots are best for pick-and-place applications and assembly. They are also used for 3D printing and CNC Machines.
Also known as spherical robots, polar robots possess an extendable arm with two rotary joints and one linear joint attached to a base that has a twisting joint. They function on a spherical work envelope, thanks to their axes that work simultaneously to form a polar coordinate system.
Polar robots are one of the first-ever developed robots intended for use in manufacturing. Typical applications include material handling, welding, die casting, injection molding, etc.
SCARA, which means Selective Compliance Articulated Robot Arm, works on 3-axis (X, Y, and Z) and has a rotary motion and end-of-arm tooling. The work envelope of a SCARA robot is cylindrical but with a greater degree of movement in a radius or an arch-shaped space.
These industrial robots are faster and have easier integration than the Cartesian types, which make them ideal for most industrial applications. SCARA robots are commonly used for BioMed applications, palletizing, and assembly. If you want to know more about SCARA robots, you can read articles about the subject in sites like robots.net for that purpose.
These industrial robots have a prismatic joint to connect the links and a rotary joint at the base. Their rotating shaft and an extendable arm with sliding and vertical motions allow these bots to function on a cylindrical work envelope.
One significant advantage of using cylindrical robots is their ability to work in a tight space. They are best to use for machine tending, simple assembly, coating applications, etc.
As its name suggests, collaborative robots or cobots are specifically designed to work alongside humans. Cobots can be separated into four types, namely: hand guiding cobots, power and force limiting cobots, speed and separation cobots, and safety monitored cobots. They are pretty common in manufacturing factories because of their wide range of uses.
Industrial robots have a lot of benefits to the manufacturing sector. They minimize human error, ensure worker safety, increase production, and reduce operating expenses. It’s crucial to know about the different types of industrial robots, especially if you’re working in the manufacturing industry.
