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. [1]
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 ...
An example of a simple open chain is a serial robot manipulator. These robotic systems are constructed from a series of links connected by six one degree-of-freedom revolute or prismatic joints, so the system has six degrees of freedom. An example of a simple closed chain is the RSSR spatial four-bar linkage.
The four parameters of classic DH convention are shown in red text, which are θ i, d i, a i, α i. With those four parameters, we can translate the coordinates from O i–1 X i–1 Y i–1 Z i–1 to O i X i Y i Z i. The following four transformation parameters are known as D–H parameters: [4] d: offset along previous z to the common normal
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 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.
Comparison diagram or comparative diagram is a general type of diagram, in which a comparison is made between two or more objects, phenomena or groups of data. [1] A comparison diagram or can offer qualitative and/or quantitative information. This type of diagram can also be called comparison chart or comparison chart.
Diagram of the Intel Core 2 microarchitecture. In electronics, computer science and computer engineering, microarchitecture, also called computer organization and sometimes abbreviated as μarch or uarch, is the way a given instruction set architecture (ISA) is implemented in a particular processor.
