ROBOTIC ARM TYPES

Robotics is an important technology of Industry 4.0, which provides extensive capabilities in the field of manufacturing. Present days robotic arms are created a great impact to the automation industry and there are lot of benefits, such as this is helpful to perform a complex hazardous job, automation, sustain high temperature, working entire time and for a long duration in assembly lines. Many robots operating in smart factories use AI to perform the tasks. There are five types of robotic arms using in the industry.

Cartesian type robotic arm

This type of arms working on the cartesian coordination system. This system identifies three axes. Each of these axes relates to movement of the arm axis from a point of origin. Below figure illustrates the three axes of the cartesian coordinate system. Notice that at the convergence of the three axes is the center point of origin.

Cylindrical type robotic arm

This type of arm has three degrees of freedom or three axes. This robotic system is called the cylindrical system because the work envelop of the robot traces out a cylinder. Below figure illustrates cylindrical coordination system of this.

Polar or spherical type

This type of arm has two rotational movements and one linear movement. This arm is also called as spherical system because of the robot’s manipulator traces out a sphere as its work envelop. Below figure illustrates the movement of polar type robotic arm.

Articulate type

That robot has two axes that have the capability of bending. This action gives the articulate robot greater flexibility in the workplace. The articulate type of robot is one of the most popular robots for industrial application. The main reason for its popularity is the flexibility of the arm. Here you can see the working coordination of Articulated type robotic arm.

Scara type

The Scara robot is most used for pick & place or assembly operations where high speed and high accuracy is required. Generally, a Scara robot can operate at higher speed and with optional cleanroom specification. The robot is a horizontally articulated manipulator with a vertical joint at the wrist end. Here you can see the structural system of the Scara robotic arm.
