The development of SCARA robots was the result of a research and development consortium launched by the University of Yamanashi and thirteen Japanese companies. This consortium operated for three years, from April 1978 to March 1981, contributing to the success of SCARA robots in industrial applications. [7]
In this convention, coordinate frames are attached to the joints between two links such that one transformation is associated with the joint [Z ], and the second is associated with the link [X ]. The coordinate transformations along a serial robot consisting of n links form the kinematics equations of the robot: [] = [] [] [] [] …
One of the links is the ground or base. [1] This configuration is also called a pantograph , [ 2 ] [ 3 ] however, it is not to be confused with the parallelogram -copying linkage pantograph . The linkage can be a one-degree-of-freedom mechanism if two gears are attached to two links and are meshed together, forming a geared five-bar mechanism.
SCARA [5] is an acronym for Selective Compliance Assembly Robot Arm. [11] SCARA robots are recognized by their two parallel joints which provide movement in the X-Y plane. [5] Rotating shafts are positioned vertically at the effector. SCARA robots are used for jobs that require precise lateral movements. They are ideal for assembly applications ...
A trivial link with three components has colorings, obtained from its standard diagram by choosing a color independently for each component and discarding the colorings that only use one color. For standard diagram of the Borromean rings, on the other hand, the same pairs of arcs meet at two undercrossings, forcing the arcs that cross over them ...
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] In contrast, a Stewart platform can change the orientation of its end effector. [3]
A typical redundant manipulator has seven joints, for example three at the shoulder, one elbow joint and three at the wrist. This manipulator can move its elbow around a circle while it maintains a specific position and orientation of its end-effector. A snake robot has many more than six degrees of freedom and is often called hyper-redundant.
Three of these joints (the shoulder, wrist and the base of the thumb) have more than one degree of freedom, all of which must be taken into account. If the model were an entire human figure, then the location of the shoulder would also have to be calculated from other properties of the model.
