Precision conveyor

A system for conveying components comprising:

• a plurality of drive rollers;
• and
• a plurality of idler rollers,
• wherein the drive rollers are operable to engage a first surface of a work piece and the idler rollers are operable to engage an opposing surface of the work piece,
• wherein at least one of the rollers comprises conductive material and provides electrical contact to the work piece when the at least one of the rollers is engaged with the work piece.

A system for conveying components, the system comprising:

• a plurality of modules, each module comprising:
• a first engaging element to engage a first surface of an object;
• a second engaging element to engage a second surface of the object, wherein the second surface is opposite the first surface, and the first and second elements engage the opposing first and second surfaces with offsetting compressive forces;
• an actuator configured to rotate at least the first engaging element to move the object in a direction substantially orthogonal to the offsetting compressive forces and with substantially no slippage;
• and
• at least one flexible coupler for connecting the plurality of modules to form a path along with the object may be moved even if the plurality of modules are misaligned.
