| Abstract: |
A robotic positioning device has a support structure and a tool implement holding member which is positional within the three dimensional space of the support structure. The tool implement holding member is connected to the support structure utilizing five positioning members. Each of these positioning members is connected to the tool implement holding member. Three of the positioning members are connected to the holding member at a first common center of rotation and the other two positioning members are connected to the holding member at a second common center of rotation. Each of the positioning members is attached to the support structure utilizing a connecting member which allows for the positioning member to freely pivot with respect to the support structure and additionally allows the member to move with respect to the support structure axially along an axis of the member. This is accomplished by moving the members axially toward or away from the support structure. Because of the movement of the individual members, any tool located on the tool implement holding member can be precisely located with respect to the support structure.

We claim:
1. A robotic device comprising:
- a support structure;
- an implement element;
- means for moving the implement element in a controlled manner consisting of first and second sets of positioning members each having two members; and a further positioning member so that there are five positioning members; and
- first and second coupling means defining two coupling points;
- said members making up a set of exactly five positioning members;
- said implement element being supported solely by said five members;
- said first set consisting of two elongated positioning members, each pivotally attached to said implement element about a first common center of rotation;
- said second set consisting of two elongate positioning members, each pivotally attached to said implement element about a second common center of rotation distal from said first common center of rotation;
- said further elongated positioning member being pivotally attached to said implement element about said first common center of rotation in association with said members of said first set of positioning members;
- first connecting means for movably attaching each of the members of said first set of positioning members to said support structure, said first connecting means operatively connecting each of said members of said first set of positioning members to said support structure;
- second connecting means for movably attaching each of the members of said second set of positioning members to said support structure, said second connecting means operatively connecting each of said members of said second set of positioning members to said support structure;
- further means for movably attaching said further positioning member to said support structure, said further means operatively connecting said further positioning member to said support structure;
- actuator means for independently moving at least the members of one of said first and second sets of positioning members axially along their elongated axes between said support structure and said implement element whereby the position of said implement element with respect to said support structure is solely controlled by said movement of said five positioning members.
