  2. Robotic arm - Wikipedia

    en.wikipedia.org/wiki/Robotic_arm

    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 ...

  3. Articulated robot - Wikipedia

    en.wikipedia.org/wiki/Articulated_robot

    Absolute accuracy is the difference between a point instructed by the robot control system and the point actually achieved by the manipulator arm, while repeatability is the cycle-to-cycle variation of the manipulator arm when aimed at the same point. Repeatability: See Figure. The ability of a system or mechanism to repeat the same motion or ...

  4. 321 kinematic structure - Wikipedia

    en.wikipedia.org/wiki/321_kinematic_structure

    Victor Scheinman's MIT Arm, built for MIT's Artificial Intelligence Lab ca. 1972, the first arm designed with a 321 kinematic structure. 321 kinematic structure is a design method for robotic arms (serial manipulators), invented by Donald L. Pieper and used in most commercially produced robotic arms.

  5. Delta robot - Wikipedia

    en.wikipedia.org/wiki/Delta_robot

    Delta robot of the FlexPicker series by ABB. Sketchy, a portrait-drawing delta robot [1] A delta robot is a type of parallel robot [2] that consists of three arms connected to universal joints at the base. The key design feature is the use of parallelograms in the arms, which maintains the orientation of the end effector. [3]

  6. SCARA - Wikipedia

    en.wikipedia.org/wiki/SCARA

    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 ...

  7. Mechanical arm - Wikipedia

    en.wikipedia.org/wiki/Mechanical_arm

    A computer-controlled mechanical arm is called a robotic arm. However, a robotic arm is just one of many types of different mechanical arms. [1] Mechanical arms can be as simple as tweezers or as complex as prosthetic arms. In other words, if a mechanism can grab an object, hold an object, and transfer an object just like a human arm, it can be ...

  8. Self-reconfiguring modular robot - Wikipedia

    en.wikipedia.org/wiki/Self-reconfiguring_modular...

    Modular self-reconfiguring robotic systems or self-reconfigurable modular robots are autonomous kinematic machines with variable morphology. Beyond conventional actuation, sensing and control typically found in fixed-morphology robots, self-reconfiguring robots are also able to deliberately change their own shape by rearranging the connectivity of their parts, in order to adapt to new ...

  9. Programmable Universal Machine for Assembly - Wikipedia

    en.wikipedia.org/wiki/Programmable_Universal...

    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. Initially developed by Unimation for General Motors , the PUMA was based on earlier designs Scheinman invented while at Stanford University based on ...
