| Abstract: |
A light weight conventional robot and method for use in connection with the surface preparation of large objects. The robot has a tool attached to an object flange which is supported by a collapsible member, allowing the tool to move to and fro. The member is pivotally mounted to a base so that the tool may be manipulated in all directions. There are at least three independently mountable blocks which allow the robot to be easily adapted to the work envelope without any change to the envelope itself. Tensile members connect the mounting blocks to the object flange to control the movement of the tool. The tensile members may be one continuous non-accumulating member or separate members which respectively allow the robot to move in two or three degrees of freedom, by varying the length of each member.

First Claim:
Show all 13 claims |
What is claimed is:
1. An object positioning mechanism adjustable with respect to a work space adaptable for working on a large workpiece such as a commercial aircraft or the like, comprising:
- a structure surrounding said work space;
- a pivot block adapted to be fixed with respect to said structure;
- an object flange spaced from said pivot block and adapted to hold a tool for working on said workpiece;
- a collapsible element having first and second members movable linearly with respect to each of other;
- the first member being pivotally connected to the pivot block and the second member being affixed to the object flange;
- a plurality of anchor blocks each being independently mountable on said structure with respect to the pivot block and the work space;
- a plurality of actuators, each mounted on a respective one of the anchor blocks; and
- tensile means including a plurality of tensile portions, at least two of said tensile portions connected at one end thereof to the object flange and at the respective other ends thereof to a respective one of the actuators, each of the actuators being energizable to change the length of its respective tensile portion by selectively pulling on its respective tensile portion whereby the tensile portions in cooperation with said collapsible element exert forces on the object flange that provide a state of force equilibrium, and wherein the anchor blocks are mountable on said structure with respect to the pivot block and each anchor block is mounted independently of each other anchor block to minimize the loading on the actuators in relation to the applied forces acting on the mechanism.
