Claim 0:
1. A robotic system for applying a fluid to a work-piece, comprising:
a support structure configured to mount at least one nozzle for spraying the fluid on a surface of the work-piece, the support structure facilitating displacement of the at least one nozzle in multiple degrees of freedom;
at least one position sensor configured to sense a position of the at least one spray nozzle and providing a position signal indicative thereof;
at least one pneumatic drive device to effect displacement of the at least one spray nozzle on the support structure along each degree of freedom provided by the support structure;
a controller, responsive to the position signal, for controlling the least one pneumatic drive device to displace the at least one spray nozzle and dispense the fluid on the work-piece; and
a horizontal cross member forming a base of an inverted U-shaped frame structure having a pair of parallel leg members, the parallel leg members pivotally mounting to vertical members of a movable carriage assembly about a horizontal axis,
a pivoting V-shaped mount for mounting the at least one spray nozzle to the horizontal cross member, each end of the V-shaped mount defining a rolling element for engaging a track in the inverted U-shaped frame structure such that the at least one spray nozzle may be displaced in a horizontal direction along the cross member and in a vertical direction along each leg member of the inverted U-shaped frame structure; and
wherein the support structure produces a cuboid-shaped frame having a stationary frame structure for mounting the movable carriage assembly, wherein the controller is disposed outside the confines of the cuboid-shaped frame and wherein the location of the controller and the at least one pneumatic drive device prohibits a source of ignition for volatiles out-gassed from the sprayed fluid, and
wherein the at least one spray nozzle mounted to the cross member is configured for side-to-side displacement in a horizontal direction orthogonal to pairs of horizontal members associated with the stationary frame structure.
