The American National Standard for Industrial Robots and Robot Systems — Safety Requirements (ANSI/RIA R15.06-1999) defines a singularity as "a condition caused by the collinear alignment of two or more robot axes resulting in unpredictable robot motion and velocities." It is most common in robot arms that utilize a "triple-roll wrist".
A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot ) or translational (linear ...
Unimate 500 PUMA (1983), control unit and computer terminal at Deutsches Museum, Munich PUMA arm at NASA. The PUMA (Programmable Universal Machine for Assembly, or Programmable Universal Manipulation Arm) is an industrial robotic arm developed by Victor Scheinman at pioneering robot company Unimation.
The SCARA is a type of industrial robot. The acronym stands for selective compliance assembly robot arm [1] or selective compliance articulated robot arm. [2] By virtue of the SCARA's parallel-axis joint layout, the arm is slightly compliant in the X-Y direction but rigid in the Z direction, hence the term selective compliance. This is ...
A six-axis articulated welding robot reaching into a fixture to weld. An articulated robot is a robot with rotary joints [citation needed] that has 6 or more Degrees of Freedom. This is one of the most commonly used robots in industry today (many examples can be found from legged robots or industrial robots). Articulated robots can range from ...
The position and orientation of a robot's end effector are derived from the joint positions by means of a geometric model of the robot arm. For serial robots, the mapping from joint positions to end-effector pose is easy, the inverse mapping is more difficult. Therefore, most industrial robots have special designs that reduce the complexity of ...
Sketch of a Unimate robot Unimate pouring coffee for a human, 1967. Unimate was the first industrial robot, [1] which worked on a General Motors assembly line at the Inland Fisher Guide Plant in Ewing Township, New Jersey, in 1961. [2] [3] [4] There were in fact a family of robots.
A robotic arm is a type of mechanical arm, usually programmable, with functions similar to a human arm; the arm may be the total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or transnational (linear) displacement.
