	<li style="list-style-type:disc; text-align:justify"><span style="font-size:14px"><span style="color:#000000"><strong>Cartesian Robots: </strong>these are the robots whose three principal axes are perpendicular to each other and are linear in nature. These three linear joints, i.e the sliding joints correspond to up-down, in-out and back-forth motions. They have high reliability and precision when it comes to operating and executing tasks in the 3-D space. Examples of the cartesian types are the motions observed in CNC machines and 3D printers.</span></span></li>
	<li style="list-style-type:disc; text-align:justify"><span style="font-size:14px"><span style="color:#000000"><strong>Cylindrical Robots:</strong> these types of robots are simple and similar to cartesian robots with the major difference that they have one rotary and two linear actuators. This makes them have a cylindrical work envelope which can be highly effective for restricted workspaces. These robots are used for pick and place applications as they have a rotary joint that allows a 360-degree reach.</span></span></li>
	<li style="list-style-type:disc; text-align:justify"><span style="font-size:14px"><span style="color:#000000"><strong>SCARA Robots:</strong> </span><span style="color:#202122">The acronym stands for Selective Compliance Assembly Robot Arm or Selective Compliance Articulated Robot Arm. A SCARA robot has two rotary and one prismatic joint. The two rotary joints linked to each other give a human arm type movement and the prismatic joint at the end effector is used for restricted motion in the Z- direction, this restricted motion is why the term &lsquo;selective compliance&rsquo; is used in its nomenclature.</span></span></li>
	<li style="list-style-type:disc; text-align:justify"><span style="font-size:14px"><span style="color:#202122"><strong>Delta Robots:</strong> these robots have a unique layout of having 3 joints rooted in a common base which is generally mounted on top (on the roof). All the tree joints have a universal joint at the root and then merge to connect their ends on a triangular end effector. The linkages, that is the arms, are designed to be parallelograms which results in giving the only translational ability to the base of the links, i.e. movement in X, Y and Z directions without any rotational requirement. A Delta robot can be understood as a spatial generalisation of a four-bar linkage. Since the actuators are rooted in the base, the arms can be made of light composite material. As a result of this, the moving parts of the delta robot have small inertia. which allows for high speed and high accelerations. Having all the arms connected to the end-effector increases the robot stiffness, but reduces its working volume.&nbsp;</span></span></li>
	<li style="text-align:justify"><span style="font-size:14px"><span style="color:#202122"><strong>Articulated Robots:</strong> </span><span style="color:#333333">Articulated robots are defined as robots containing rotary joints. They can be as simple as a two-axis structure or complex with ten or more axes and are typically powered by servo motors. Most industrial robots have four to six axes, with six axes being the most common. Each joint provides an additional degree of freedom (DoF). An articulated robot begins with a base that is generally vertical to the ground, which contains the first joint. It is further connected to the base through this first revolute joint, and another revolute joint operates perpendicular to the body and connects the shoulder; this chainlike structure continues as necessary. At the end of the robot additional joints are then used to attach the robot wrist and end effector. This robotic structure is designed to closely mimic the human arm.<span style="color:#202122"> </span>Articulated robots provide more dexterity than any other robot type, which is why they are commonly utilized amongst manufacturers.</span></span></li>
