Abstract
A two-armed transfer robot is provided which includes an upper arm mechanism and a lower arm mechanism which is substantially identical to the upper arm mechanism. Each arm mechanism is provided with a handling member for carrying a workpiece to be processed. Each arm mechanism is also provided with a pantograph assembly consisting of a base arm, an outer link, a pair of intermediate links and an inner link. The handling member of each arm mechanism is arranged to be spaced from a central driving shaft when the handling member is retreated closer to the shaft. The base arm of the pantograph assembly is inclined away from the handling member when the handling member is retreated closer to the shaft. At the same time, the intermediate links are also inclined away from the handling member.
