Rapid technological advancements in automation and robotics have spurred the adoption of industrial robots in various areas of production. At the forefront of these advancements are manufacturers, they are tasked with building these robots as per the industry needs.
Robots are manufactured in all specifications, shapes, and sizes. Their main differentiators are workspace, speed, and size. Industrial robot clients must be knowledgeable of each aspect and inform the manufacturers of what suits their factories best.
Industrial robots are becoming more prevalent in all sectors of production. The reason for all this extensive mechanization by companies is because of faster and more precise results by these universal robots. This review will divulge into the different types of industrial robots that are manufactured.
Types of industrial robots currently being manufactured
A simpler yet more conclusive focus on industrial robots manufactured can be narrowed down to these five SCARA, Delta, Cylindrical, Cartesian, and Six-axis.
Also known as gantry or linear robots, Cartesian robots are the most commonly manufactured robots. This is because of the client’s fondness and being termed as stress-free to use and program. Also, their structures are flexible enabling users to adjust swiftness and stroke
Cartesian robots operate on a three linear axis system; X, Y, and Z. This basically means that they travel straight on three axis; side to side, up and down, in and out. They have an excellent range of operation that is up to tens of meters.
SCARA is an acronym that signifies; selective compliance articulated robot arm or particular compliance assembly robot arm. Like Cartesian robots do, SCARA robots also function on three axis and, in addition to that, have rotary movements as well. They are considered as all in one robot.
SCARA robots are very proficient in sideways movements and move faster and are easier to integrate than Cartesian robots. SCARA robots require a small working space, and thus application areas include Bio-Med and palletizing.
In terms of axis motion, cylindrical robots are similar to Cartesian robots. Cylindrical robots have one cylindrical joint bonding the links and another joint, which is rotary at the base. These robots have a prismatic working area with a pivoting shaft and an expandable arm that moves vertically.
Prismatic shaped robots provide parallel and perpendicular linear movements as well as rotational motion about the vertical axis. The minimalistic outline of the end arm enables it to reach tight and restricted workspaces without loss of repeatability and speed. Cylindrical robots are used for applications such as picking, rotating, and placement.
Delta robots, also referred to as parallel link robots they are by far the fastest and most expensive robots. They consist of horizontal joint linkages connected to a universal pedestal. Delta robots work in a dome shape and have precision and delicate movements at very high velocity due to each linkage of the end effector being directly moved by all three arms.
Delta robots are by far the best suited for product transfer or pick and place applications such as moving parts from one conveyor belt to the next. However, they are astonishingly complicated to use in comparison with other robots. Real-life applications include the food, electronics, and pharmaceutical industries.
6-axis robots are made in all shapes and sizes and are also considered to be all in one robot as well. Though 6-axis robots can be miniature-sized, typically they are enormous and are typically used in assembly procedures such as fixing seats in cars
6-axis robots operate like a human arm meaning they can move something from one point to another. Programming these robots is frenetic due to the various sizes and shapes and are desired as they can make rotations that other robots cannot make.
To sum it all up, when companies are making these robots, they consider speed, precision, duty cycle, orientation, and load, among others. Determining these elements enable for production of the most effective and efficient robots.
