Abstract:
1. A robot arm assembly comprising: a first link arm including an elongated housing having a first end and a second end, a first non-rotating cam disposed within the housing at the first end and a first four bar link mechanism engageably coupled to the first cam wherein the first cam is fixedly coupled to a non-rotating shaft mounted co-axially within a first rotating shaft sleeve, wherein the first link arm is coupled to the first rotating shaft sleeve and is rotatable with the first shaft sleeve about the shaft defining a primary pivot axis; a first translating arm pivotably connected to the second end of the first link arm and pivotably engaged by the four bar link mechanism; and a first end effector coupled to the translating arm, wherein rotation of the first link arm and shaft sleeve about the shaft mechanically engages the first four bar link mechanism with the first cam and pivotably moves the translating arm about a secondary pivot axis.
