| Abstract: |
An automatic robot structure includes a fixed location support 10 which carries three locational arms 12, 14, 16, being hingedly connected to each other at their location of convergence to support a workhead 20, the driving motors 12a, 14a, and 16a each being independently operable to drive its respective arm in an axial direction, each of the arms being rigid in the sense that no part of the arm is hingedly connected to another part, so that the forces derived from a payload weight subject the arms primarily only to compression and or tension.

First Claim:

I claim:
1. A robotic manipulator for automatically positioning a workhead comprising:
- a support structure;
- three arms having their remote end portions hingedly connected together at a single location which is at least relatively close to the point of intersection of the axes of the three arms, said location being adjacent the workhead connected to said three arms, and having their proximate end portions carried in gimbaled relation from said support structure at spaced apart locations thereat together defining the points of a triangle;
- means for driving each arm axially and independently to move said workhead to different positions, said driving means being carried by said support structure and being fixed in location at said support structures, said workhead being in rigid relation to one of said three arms and spaced from said single location;
- each arm being substantially straight from its remote end portion to its proximate end portion and rigid for its length in the sense that no part of the arm is hingedly connected to another part so that the forces derived from the payload weight and movement subject said arms primarily only to compression and/or tension.
