Work envelopes can be cubic, rectangular, cylindrical, polar, and revolute, among others. The shape or volume of space of a work envelope varies by robot type, reach, and number of axes. A robot's reach will determine the span of a robot's arm movements.
What is the work envelope of a medical robot?
The work envelope is the boundary of positions in space that the robot can reach. The workspace is defined by the kinematic configuration of the robot (type of DOFs, orientation of joints) as well as by the ROM of each joint.
What are the benefits of a Cartesian work envelope?
The primary advantage of cartesians is that they are capable of moving in multiple linear directions. In addition, cartesians are able to do straight-line insertions into furnaces and are easy to program. Cartesians have the most rigid robotic structure for a given length, since the axes are supported at both ends.
What is robot work volume?
A space on which a robot can move and operate its wrist end is called as a work volume. It is also referred as the work envelope and work space. ... The maximum value for moving a robot joint. The size of the robot components like wrist, arm, and body.Oct 17, 2011
What are the factors that affect the size and shape of work envelope?
The size and shape of the work envelope depends on the coordinate geometry of the robot arm, and also on the number of degrees of freedom. Some work envelopes are flat, confined almost entirely to one horizontal plane. Others are cylindrical; still others are spherical. Some work envelopes have complicated shapes.Mar 29, 2013
What is the work envelope of an articulated robot?
Work Envelope: A three-dimensional shape that defines the boundaries that the robot manipulator can reach; also known as reach envelope.
What is meant by a work envelope?
A robot's work envelope is its range of movement. It is the shape created when a manipulator reaches forward, backward, up and down. These distances are determined by the length of a robot's arm and the design of its axes.
What is a work envelope in welding?
A work envelope is a defined area of space needed to perform production related tasks in manufacturing. ... The length of their arm determines how much space they can access while their axes determine what angles they can obtain within that space.
Why work envelope is important in robot safety?
A robot's work envelope is important because it defines the area in which a robot will be able to operate in. Industrial robots are unable to operate outside of their work envelope. It is especially important when selecting an industrial robot to have a clear definition of the workspace needed for your application.
