Scara robot (Adept Cobra 600)

The Selective Compliant Articulated/Assembly Robot Arm (SCARA) is usually a 4-axis industrial robot. The kinematics is like a human arm, with the first joint being referred to as the shoulder and the second as the elbow. These two joints allow movement in the X- and Y- axes. The third joint is a translation joint and moves along the Z-axis. The last joint, called Theta-Z, gives a rotation around the Z-axis (wrist rotation).

Scara robot (Adept Cobra 600) File history Legend: (cur) = this is the current file, (del) = delete this old version, (rev) = revert to this old version. ... A coordinate axis is one of a set of vectors that defines a coordinate system. ... An industrial robot is officially defined by ISO (Standard 8373:1994, Manipulating Industrial Robots – Vocabulary) as an automatically controlled, reprogrammable, multipurpose manipulator programmable in three or more axes. ... In physics, kinematics is the branch of mechanics concerned with the motions of objects without being concerned with the forces that cause the motion. ...


SCARA robots reportedly offer the best price/performance ratio as regarding speed. They are faster than cartesian robots (because they move less mass) and 6-axis robots (because they have fewer joints and are usually more rigid). A cartesian coordinate robot is an industrial robot whose three principal axes of control are linear (i. ... Mass is a property of physical objects that, roughly speaking, measures the amount of matter they contain. ...


They are very common in pick-and-place, assembly, and packaging applications. The electronic printed circuit board industry, in particular, use large numbers of SCARAs for placing semiconductor ICs and other components on the circuit boards of computers and related equipment. Close-up photo of one side of a motherboard PCB, showing conductive traces, vias and solder points for through-hole components on the opposite side. ... An integrated circuit (IC) is a thin chip consisting of at least two interconnected semiconductor devices, mainly transistors, as well as passive components like resistors. ...

SCARA robot and articulator - Patent 6068442 (3425 words)
The robot of claim 1 further comprising a fourth motor in the quill having an output shaft for turning in a plane of rotation parallel to the first and second planes of rotation.
The robot of claim 1 further comprising a linear encoder coupled to the quill for generating a signal representative of the linear position of the quill.
The robot of claim 6 further comprising one or more displacement encoders coupled to the control means and to the motors and to the quill for generating signals representative of the positions of the motors and the quill.
Scara vs. Cartesian Robots: Selecting the Right Type for Your Applications. . . . by Bennett Brumson - Robotics ... (1285 words)
Scara's are ideal for a variety of general-purpose applications requiring fast, repeatable and articulate point to point movements such as palletizing, depalletizing, machine loading/unloading and assembly.
Due to their ''elbow'' motions, scara robots are also used for applications requiring constant acceleration through circular motions like dispensing and in-place gasket forming.
Scara robot joints are all capable of rotation and can be thoroughly sealed and safeguarded which is necessary should the robot be deployed in dusty or corrosive environments, or for applications under water.
