Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
242 words
A multiarticulation robot comprising a rotatable stand; a first rotary articulation mechanism for rotating said stand; a first arm pivotally journalled on said stand; a first rocking articulation mechanism for rocking said first arm; a second arm pivotally mounted at the opposite end of said first arm; a second rocking articulation mechanism for rocking said second arm; a third arm slideably extending from said second arm; a second rotary articulation mechanism for rotting said third arm; a first shaft rotatably mounted at the end of said third arm at an axis intersecting the axis of said third arm; a third rotary articulation mechanism for rotating said first shaft; a second shaft rotatably mounted at the end of said first shaft at an axis intersecting, at right angles, said first shaft; a third rocking articulation mechanism for rocking said second shaft about an axis; a fourth arm mounted on said second shaft and conjointly rocking therewith; a third shaft mounted at the end of said fourth arm, having an axis extending transversely to the plane in which said fourth arm rocks; a fourth rocking articulation mechanism for rocking said third shaft; a fifth arm mounted at one end to said third rotary shaft and conjointly rocking therewith; a fourth rotary shaft mounted at the end of said fifth rm, having an axis extending transversely to the plane in which said fifth arm rocks; a fourth rotary articulation mechanism for rotating said fourth shaft.
