Robotic System

A drive system comprises a support structure for a guideway defining an X-Y array of tracks () so that one or more carriages () can run along the tracks to any desired position. The carriages are intended to either carry a single robotic device or work together to carry a larger robotic device. The track is made up of an array of pegs () supported from a ceiling plane made up of an array of tiles () which provide for electrical connections to the carriages. Each peg carries a spool mounted between two horizontal flanges that cooperates with a rectangular sprocket connected to a base of a cuboid carriage housing. The carriages are driven by internal electric motors that are arranged to drive two pairs of omniwheels () on the ceiling plane while the carriage is supported and guided by means of its sprocket. 112-. (canceled)13. A system for overhead support and control of a suspended robotic device , comprisinga frame;a guideway comprising a plurality of pegs depending from the frame and arranged in orthogonal rows and columns, each peg carrying a horizontal flange, wherein the flanges form a planar surface;at least one carriage for supporting a robotic device, having a cuboid housing with a top, base and four sides and a depending neck supporting a guide sprocket;wherein the pegs are spaced to permit the carriage to move between them, each peg includes a spool below the flange configured to interact with the carriage guide sprocket in order to guide the carriage, and the flanges comprise a planar guideway and bearing surface for the base of the carriage housing.14. The system of wherein each peg has a second horizontal flange attached below the spool to provide a bearing surface for the sprocket of the carriage.15. The system of wherein the carriage neck carries a connecting plate for connection to a robotic device.16. The system of wherein the sides of the carriage have projecting pinwheels which can be used to lock the carriage in position against a peg.17. The ...
