| Abstract: |
A self-propelled robot platform consists of a frame with a plurality of casters to support the frame on and space the frame from a supporting surface, as well as permitting any selected direction of movement over the support surface. At least two linear motors are arranged on the frame transversely to one another and generally parallel to the support surface and so that their flux links the support surface. The support surface is preferably a conductor such that by a combination of signals to the respective motor means, the motor fluxes linking the supporting surface will drive the platform. The platform is provided with tool support means and that tool support means includes articulation structure with associated drive means which permits tool positioning. As a consequence, the robot platform may be moved over the surface in a predetermined pattern doing work with a supported tool or it may be moved from point to point where work is to be done where the tool is actuated either manually or by programmed information. If the support surface is magnetic, the surface need not be horizontal to hold the platform.
A system for driving the platform includes input means for selecting platform movement and tool operation, which may include both manual and computer control. The input means, in turn, drives control means to select the appropriate linear motor means at a given time and sequence to achieve desired movement. Control means selects the motors to be energized by a power source. A means is also provided to drive the respective drive means of the articulation structure to produce desired tool movement. Both platform and tool position sensing signals are preferably fed back to the drive means to correct their drive signals.

We claim:
1. A self-propelled robot platform for cooperative use in connection with a support surface permitting magnetic interaction between the platform and the support structure comprising:
- a frame;
- a plurality of frame support members supported on the frame, adapted to cooperate with the support surface to support and space the frame from the surface and permitting movement over the support surface in any selected direction;
- at least two linear motor means fixed to the frame transversely to one another and generally parallel to the support surface in position to magnetically link the support surface or means generally conforming to the support surface such that, by a combination of signals to the respective transversely positioned motor means, the motor means can drive the platform in a variety of selected directions and along a selected path or pattern; and
- tool support means including articulation structure permitting tool position adjustment, whereby a tool supported by the tool support means may do predetermined work at predetermined locations of the platform.
