What do you mean by parallel manipulator?

A parallel manipulator is a mechanical system that uses several computer-controlled serial chains to support a single platform, or end-effector. Perhaps, the best known parallel manipulator is formed from six linear actuators that support a movable base for devices such as flight simulators.

What is spherical parallel manipulator?

A spherical parallel manipulator (SPM) is a mechanical device composed of a moving platform and a fixed platform connected to each other by means of two or more kinematic chains, the main virtue of which is that all points of the moving platform move on concentric spheres according to a point of the moving platform …

What is a parallel robot used for?

Besides serial kinematics, parallel robots are focused on for handling and assembly tasks. In contrast to serial kinematics, not all joints carry drive engines. The drive engines are usually located at the platform. Therefore, the moved mass is smaller and high-dynamic tasks can be addressed.

What is spatial motion?

3.1 Planar and Spatial Mechanisms In a planar mechanisms, all of the relative motions of the rigid bodies are in one plane or in parallel planes. If there is any relative motion that is not in the same plane or in parallel planes, the mechanism is called the spatial mechanism.

Which joint is called prismatic joint?

A prismatic joint is a connection between two objects that allows relative motion along a single axis. A prismatic joint is often called a slider — as for example a “crank-slider linkage.” This is a type of kinematic pair and an idealized way to describe how motions are constrained within machines.

What is articulated manipulator?

The articulated manipulator is an industrial robot with rotary joints and is also called a revolute, or anthropomorphic manipulator. • Articulated robots can range from simple two-jointed structures to systems with 10 or more interacting joints.

What are spherical robots used for?

Spherical mobile robots have applications in surveillance, environmental monitoring, patrol, underwater and planetary exploration, rehabilitation, child-development, and entertainment. Spherical robots can be used as amphibious robots viable on land as well as on (or under) water.

How does Scara robot work?

SCARA Robots are a popular option for small robotic assembly applications. The SCARA’s structure consists of two arms joined at the base and the intersection of arms one and two. Two independent motors use inverse kinematics and interpolation at joints J1 and J2 to control the SCARA’s X-Y motion.

What spatial means?

1 : relating to, occupying, or having the character of space. 2 : of, relating to, or involved in the perception of relationships (as of objects) in space tests of spatial ability spatial memory. Other Words from spatial More Example Sentences Learn More About spatial.

What is spatial velocity?

A spatial velocity is sometimes called a twist; a spatial force is sometimes called a wrench. While the rotational component of a spatial vector applies to a rigid body or frame as a whole, the translational component refers to a particular point rigidly fixed to that same body or frame.

Why is it called a prismatic joint?

A prismatic joint is a connection between two objects that allows relative motion along a single axis. Motion that’s perpendicular to this axis (or rotation about any axis) is prevented. This means the joint has one degree of freedom (1-DOF). A prismatic joint allows only linear motion along a single axis.

Where is prismatic joint used?

Prismatic joints: prismatic joints have one DoF and are used to describe translational movements between objects. Their configuration is defined by one value that represents the amount of translation along their first reference frame’s z-axis. They can be used as passive joints, or as active joints (motors).

Which is the best description of a parallel manipulator?

Abstract render of a Hexapod platform (Stewart Platform) A parallel manipulator is a mechanical system that uses several computer-controlled serial chains to support a single platform, or end-effector. Perhaps, the best known parallel manipulator is formed from six linear actuators that support a movable base for devices such as flight simulators.

Which is the best definition of spatial manipulation?

Spatial Distortion: Bending the curvature of the three-dimensional space to distort anything within. Spatial Empowerment: Draw and gain strength from space itself. Spatial Mimicry: User can occupy an amount of physical, three-dimensional space without using physical form.

Is the singularity of a parallel manipulator an open problem?

The determination of the singular positions is difficult (for a general parallel manipulator, this is an open problem). This implies that the workspaces of the parallel manipulators are, usually, artificially limited to a small region where one knows that there is no singularity.

How does spatiolock use time and space manipulation?

Spatiolock by placing themselves outside space. Time Travel by phasing through the spatial barriers that separate different timelines. A user who can also use Time Manipulation is able to learn Space-Time Manipulation . May be unable to create space, being limited to manipulating only the already existing one.
