A Cartesian coordinate robot (also called linear robot) is an industrial robot whose three principal axes of control are linear (i.e. they move in a straight line rather than rotate) and are at right angles to each other. [1] The three sliding joints correspond to moving the wrist up-down, in-out, back-forth. Among other advantages, this ...
The first industrial robot, [1] Unimate, was invented in the 1950s. Its control axes correspond to a spherical coordinate system, with RRP joint topology composed of two revolute R joints in series with a prismatic P joint. Most industrial robots today are articulated robots composed of a serial chain of revolute R joints RRRRRR.
ST Robotics has 5 robot models R12 - 5 or 6 axis low cost robot arm, 500g payload speeds up to 180 deg/s R15 - 3 or 4 axis Cartesian robot system using Igus Cartesian robot system with an ST Robotics controller R17 - 5 or 6 axis robot arm, 3 kg payload R17HS - as R17 but using Teknic servomotors, 2 kg payload, speeds up to 180 deg/sec
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 ...
Cartesian robots, [5] also called rectilinear, gantry robots, and x-y-z robots [6] have three prismatic joints for the movement of the tool and three rotary joints for its orientation in space. To be able to move and orient the effector organ in all directions, such a robot needs 6 axes (or degrees of freedom).
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 ...
The typical 3D "bridge" CMM allows probe movement along three axes, X, Y, and Z, which are orthogonal to each other in a three-dimensional Cartesian coordinate system. Each axis has a sensor that monitors the position of the probe on that axis, with typical accuracy in the order of microns. When the probe contacts (or otherwise detects) a ...
A manipulator can move an object with up to 6 degrees of freedom (DoF), determined by 3 translation 3T and 3 rotation 3R coordinates for full 3T3R mobility. However, when a manipulation task requires less than 6 DoF, the use of lower mobility manipulators, with fewer than 6 DoF, may bring advantages in terms of simpler architecture, easier control, faster motion and lower cost.
