Head for a robot or manipulator comprising a control casing and at least two shafts perpendicular to each other, with corresponding external members rotatably driven from separate control servo motors, one shaft being rigid with one of said members which supports the other shaft, said servo motors are fixedly mounted in said casing so as to drive at least two coaxial shafts, while the driving of at least one of said perpendicular shafts from one of said coaxial shafts takes place through a bevel gear of which the input pinion is rigid with this one coaxial shaft and the output pinion is rigid with the shaft concerned. This head construction permits assembling the servo motors into a readily accessible unit by providing said coaxial shafts with concentric toothed members in meshing engagement with driving pinion driven in turn from said servo motors, and is applicable notably to robot heads having two or three degrees of freedom.
Robot or manipulator head comprising a control casing and at least two perpendicular shafts and corresponding external members rotatably driven from driving servo motors, one of said perpendicular shafts being rigid with one of said members supporting the other perpendicular shaft, said servo motors fixedly mounted in said control casing being drivingly connected to at least two coaxial shafts, while at least one of said perpendicular shafts is driven from one of said coaxialshafts through a bevel gear of which the input pinion is rigid with said one coaxial shaft and the output pinion is rigid with said one perpendicular shaft.
