Class Vocabulary

Vocabulary TermDefinition
A rotational axis that describes motion around the X-axis.
A mathematical process designed to systematically solve a problem.
A type of robotic arm that closely resembles a human arm. The arm of an articulated robot has revolute joints and the number of joints can vary.
Imaginary straight lines or circles used to describe the location or movement of an object in the Cartesian coordinate system.
A rotational axis that describes motion around the Y-axis.
A numerical system that describes the location of an object by numerically expressing its distance from a fixed position along three linear axes.
A type of robotic arm that has prismatic joints only. The linear movement of the joints gives the Cartesian robot a highly rigid structure that allows it to lift heavy objects.
A rotational axis that describes motion around the Z-axis.
A type of programmable control system, directed by mathematical data, which uses microcomputers to carry out various machining operations.
A type of robot programming that has the manipulator move smoothly without stopping along its path.
The available ways a component can move in three-dimensional space along an axis. Robots typically have 3 to 6 degrees of freedom.
The end component of a robotic arm that is shaped like a hand or like a specialized tool. Also known as end-of-arm tool (EOAT).
The calculating of the position or motion of each robotic link as a function of joint displacements.
A programmable mechanical device that is used in place of a person to perform dangerous or repetitive tasks with a high degree of accuracy.
The calculating of joint displacements needed to move the end-effector to a desired position and orientation.
A matrix quantity that maps velocities in joint space to velocities in Cartesian space.
The location at which two or more parts of a robotic arm make contact. Joints allow parts to move in different directions.
The space defined by a vector that contains the displacement of each joint linkage relative to a reference point.
The science of motion without regard for the forces that cause that motion. In robotics, kinematics involves studying the mapping of coordinates in motion.
A joint that moves in a straight line across one axis. Also known as a prismatic joint.
Movement in a straight line across one axis.
A fastener that joins or connects the parts of a robotic arm.
A function that matches elements from one data set to a unique element in another data set. In robotics, Jacobians map data from joint space to Cartesian space.
A set of velocities that is expressed as a series of vectors.
The fixed, central point in the Cartesian coordinate system. The origin has a numerical value of zero at each axis.
A series of numerical instructions used by a CNC machine to perform the necessary sequence of operations to machine a specific workpiece.
A type of robot programming that has the manipulator reach a set point, stop, complete its task, and then move to the next set point.
A set of three vector points along a specific axis that is used to fix a location in space.
A joint that moves in a straight line across one axis. Also known as a linear joint.
A joint that rotates around more than one axis.
An angle formed by two lines that are perpendicular to one another. The corners of a piece of paper form right angles.
A quick reference that shows the X-, Y-, and Z-axes. A person displays his or her right hand, and the first three fingers from the right each represent the X-, Y-, and Z-axis in order.
A mathematical way to describe a point in space by using vectors of the principal axes in terms of the attached coordinate system.
The axes that describe turning or rotation around the linear axes.
Points at which the calculation of the Jacobian does not have a unique solution.
A process used to program a robot and control its movements.
A robot coordinate system that sets the origin at the end-effector. Tool coordinates change their orientation as the tool moves.
The process of computing different motion functions so that a robot's various joints move in a coordinated fashion.
Amounts or measurements that are related to a direction. Velocity, acceleration, and weight are vector quantities.
An intermediate location through which the manipulator must pass on its way to the destination. Via points are required for circular motion because three points are needed to define the function of a circle.
The defined area of space through which a robot can move. Also known as the work envelope.
The defined area of space through which a robot can move. Also known as the work cell.
A robot coordinate system that sets the origin at the centerline of the first joint. World coordinates are static.
The linear axis representing side-to-side movement in a robot, relative to the origin.
The linear axis representing back and forth movement in a robot, relative to the origin.
