The Association for Advancing Automation (A3) is an international trade group that serves the robotics industry. It was founded in 1974 and is headquartered in Ann Arbor, Michigan. The organization is involved in safety standards for robots, [1] and sponsors robotics conferences. On April 14, 2021 the Robotic Industries Association, AIA ...
Robotics engineering is a branch of engineering that focuses on the conception, design, manufacturing, and operation of robots. It involves a multidisciplinary approach, drawing primarily from mechanical , electrical , software , and artificial intelligence (AI) engineering .
The reverse process that computes the joint parameters that achieve a specified position of the end-effector is known as inverse kinematics. The dimensions of the robot and its kinematics equations define the volume of space reachable by the robot, known as its workspace.
Articulated Robot: See Figure. An articulated robot uses all the three revolute joints to access its work space. Usually the joints are arranged in a “chain”, so that one joint supports another further in the chain. Continuous Path: A control scheme whereby the inputs or commands specify every point along a desired path of motion. The path ...
Serial robots usually have six joints, because it requires at least six degrees of freedom to place a manipulated object in an arbitrary position and orientation in the workspace of the robot. A popular application for serial robots in today's industry is the pick-and-place assembly robot, called a SCARA robot, which has four degrees of freedom.
Line representations in robotics are used for the following: They model joint axes: a revolute joint makes any connected rigid body rotate about the line of its axis; a prismatic joint makes the connected rigid body translate along its axis line. They model edges of the polyhedral objects used in many task planners or sensor processing modules.
For each joint of the kinematic chain, an origin point q and an axis of action are selected for the zero configuration, using the coordinate frame of the base. In the case of a prismatic joint, the axis of action v is the vector along which the joint extends; in the case of a revolute joint, the axis of action ω the vector normal to the rotation.
The following outline is provided as an overview of and topical guide to robotics: . Robotics is a branch of mechanical engineering, electrical engineering and computer science that deals with the design, construction, operation, and application of robots, as well as computer systems for their control, sensory feedback, and information processing.
