What is the difference between a parallel robot and a 4\u2011axis robot?<\/span><\/strong><\/p>\n

\n

I. Clarification: “4\u2011Axis Robot” Typically Means SCARA<\/span><\/h3>\n

In industrial robotics, the term\u00a0<\/span>“4\u2011axis robot”<\/span><\/strong>\u00a0almost always refers to a\u00a0<\/span>SCARA robot<\/span><\/strong>\u00a0(Selective Compliance Assembly Robot Arm), which has four axes of motion:<\/span><\/p>\n

Axis<\/span><\/th>\nMotion<\/span><\/th>\n<\/tr>\n<\/thead>\n
Axis 1<\/span><\/td>\nRotation about the vertical axis (waist)<\/span><\/td>\n<\/tr>\n
Axis 2<\/span><\/td>\nRotation about the vertical axis (arm)<\/span><\/td>\n<\/tr>\n
Axis 3<\/span><\/td>\nLinear motion (vertical Z\u2011axis)<\/span><\/td>\n<\/tr>\n
Axis 4<\/span><\/td>\nRotation about the vertical axis (wrist \/ theta)<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

A\u00a0<\/span>parallel robot<\/span><\/strong>\u00a0(also called a delta robot or spider robot) typically has\u00a0<\/span>3 or 4 axes<\/span><\/strong>\u00a0as well, but the structure and motion generation are fundamentally different.<\/span><\/p>\n
