In general,traditional SCARA’s are 4-axis robot arms,i.e.,they can move to any X-Y-Z coordinate within their work envelope.There is a fourth axis of motion which is the wrist rotate (Theta-Z).The ‘X’,‘Y’ and the ‘Theta-Z’ movements are obtained with three parallel-axis rotary joints.The vertical motion is usually an independent linear axis at the wrist or in the base.
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 Compliant.This is advantageous for many types of assembly operations,e.g.,inserting a round pin in a round hole without binding.
The second attribute of the SCARA is the jointed two-link arm layout similar to our human arms,hence the often-used term,Articulated.This feature allows the arm to extend into confined areas and then retract or “fold up” out of the way.This is advantageous for transferring parts from one cell to another or for loading/ unloading process stations that are enclosed.
SCARA’s are generally faster and cleaner than comparable Cartesian systems.Their single pedestal mount requires a small footprint and provides an easy,unhindered form of mounting.On the other hand,SCARA's can be more expensive than comparable Cartesian systems and the controlling software requires inverse kinematics for linear interpolated moves.This software typically comes with the SCARA though and is usually transparent to the end-user

一般来说,传统SCARA的是4轴机器人手臂,也就是说,它们可以移动到任何XYZ其工作范围内的坐标.有运动是手腕旋转（ θ- Z）的第四轴.的“X” ,“Y”和“ θ- Z'运动与三个平行轴旋转接头获得的.的垂直方向运动,通常是在手腕或在基独立线性轴.
凭借SCARA的平行轴关节设计,手臂在XY方向稍微兼容,但刚性的“Z”方向,因此,长期：选择性标准.这是有利的,对于许多类型的组件的操作,例如,插入一个圆针中的圆孔无约束力.
该SCARA的第二个属性是铰接式双连杆臂布局类似我们人类的武器,因此经常使用的术语,铰接式.此功能允许手臂延伸到狭窄区域,然后缩回或“折叠”出的方式.这是有利的,用于将部件从一个小区到另一个,或者用于使用封闭装/卸站的过程.
SCARA机器人的一般速度更快,比同类笛卡尔系统清洁.他们的单座安装需要占用空间小,并提供了安装的方便,不受阻碍的形式.另一方面,SCARA的可以比可比较的笛卡尔系统更加昂贵和控制软件需要逆运动学的线性内插的移动.该软件通常带有该SCARA虽然,通常是透明的,最终用户.到这就完了,你应该没写完,你要不选我你试试,纯手打的累吐血了.
再问： (⊙o⊙)…谷歌翻译的吧。。。。。。
