Types of Robotic Arm and Its Uses | Robotic solution in delhi

These are machines that are programmed to execute a specific task or job quickly, efficiently, and extremely accurately. Generally motor-driven, they are the most often used for the rapid, consistent performance of heavy and/or highly repetitive procedures over extended periods of time, and are especially valued in the industrial production, manufacturing, machining and assembly sectors.

A typical industrial robot arm includes a series of joints, articulations and the manipulators that work together to closely resemble the motion and functionality of a human arm (at least from a purely mechanical perspective). A programmable robotic arm can be a complete machine in and of itself, or it can function as an individual robot part of a larger and the more complex piece of the equipment.

There are numerous different robotic arm types available on today’s market, each designed with the important core abilities and functions that make various specific types particularly well-suited for particular roles or industrial environments.

Cartesian (gantry) robotic arms: They often referred to as rectilinear or gantry robot arms — are named after the Cartesian coordinate system, developed by René Descartes in the 17th century as a way to map geometric curves onto a graph through the use of algebraic equations.

If all that sounds frighteningly complex, the practical reality is actually quite familiar to most of us in a day-to-day workplace uses: Cartesian coordinates are essentially what give us the widely used system of X, Y and (less commonly) Z axes that we almost always see mapped on any typical graph.

In robotic arm terms, the mechatronic Cartesian or gantry robots tend to consist of three articulating joints that are programmed using these X. Y and Z coordinates to specify the linear movement in three dimensions along with these three axes. The wrist joint often provides further rotational functionality.

These arms use various motors and linear actuators to position a tool or attachment somewhere in three-dimensional space, and manipulate it through a series of linear movements to switch between positions. They can be mounted horizontally, vertically or overhead, and are widely used in a range of applications such as machining parts or picking and placement alongside the conveyor belts.

Cylindrical robotic arms: These robotic arms, in contrast to the Cartesian versions outlined above, are ones whose axes form a cylindrical coordinate system — in short, their programmed movements take place within a cylinder-shaped space (up, down and around). This type of arm is more commonly used for assembly operations, spot-welding and machine tool handling, where the rotary and prismatic joints give it both the rotational and linear motion.

Polar/Spherical robotic arms: Again, just like the cylindrical robotic arms described above, a polar or spherical robot is one that operates within a spherical ‘work envelope’ or potential locus of movement. This is achieved through a combined rotational joint, the two rotary joints, and a linear joint. The polar robotic arm is connected to its base via a twisting joint, and the subsequent spherical workspace has access to make it useful for performing the similar roles as cylindrical robotic arms — handling machine tools, spot welding, die casting and the arc welding.

SCARA robotic arms: These arms are most widely used in assembly and pick and place applications. The acronym SCARA stands for Selective Compliance Assembly Robot Arm (or sometimes Selective Compliance Articulated Robot Arm), which is a reference to their ability to tolerate a limited degree of ‘compliance’ — flexibility, in the context of robotics — along with the some axes, while remaining rigid in others.

In every case, selecting the right type of programmable robot arm for a given role or task should involve consideration of the intended application’s precise nature and requirements. These will typically include:

• Load

All types of robotic arms have a given load capacity, and this manufacturer-specified number always needs to exceed the total weight of the payload involved in any job you expect the arm to perform (including tools and attachments).

• Orientation

This criterion is generally defined by the footprint and mounting position of the robotic arm, and how well it fits alongside the other equipment in your production line for the range of movements and manipulations it’s expected to perform. This will in turn influence where the arm can physically be positioned relative to the objects it will be moving.

• Speed

Particularly when choosing robotic arms for picking and placement applications, it is important to pay attention to manufacturer ratings for speed and especially in terms of acceleration over longer distances.

• Travel

Tolerances and accuracy over wider spans can be reduced in certain types of robot arms, due to arm deflection and differences in support framework design.

If the application requires longer travel distances between the payloads or work areas, this may dictate which sorts of robotic arms would be suitable or unsuitable for performing the task, depending on the tightness of tolerances required.

• Precision

Certain types of programmable robotic arms are inherently designed to be more precise in their range of movements and articulations than others. This may come at a higher cost for a more complex machine, and involve a compromise against other factors such as footprint, speed, potential travel distance and orientation.

• Environment

Consideration of atmospheric conditions and potential hazards (including dust, dirt and moisture levels) in the immediate working environment will be important when choosing an appropriate type of robotic arm for a specific location.

• Duty cycle

This is essentially an evaluation of how intensively the robotic arm will be expected to perform, and for how long between ‘rest’ or maintenance periods. Wear and tear will obviously become a problem sooner for a robot arm that is run continuously, as opposed to one which is only operated during the standard shift cycles.
