AUTOMATED TROWELLING SYSTEM

An automated trowelling system (10) for providing a smooth, even finish to o ne or both sides of a wall (12). The present system smooths wet surface materia ls such as concrete or plaster quickly and consistently with minimum manual intervention. Horizontal brackets (30, 32) on the wall (12) support a horizontally translating column (22) and an associated vertically reciprocating trowel (34). A first motor (28) propels the column (22) and trowel laterally along the wall (12), while a second motor (38) effects vertical motion. A forward scoop (42) removes excess wall finishing material ahead of the reciprocating trowel (34), and a nonreciprocating finish trowel (44) follows the reciprocating trowel (34) to provide enhanced finish to the wall (12). A processing unit enhances the ability of the system to operate with minimum manual intervention. Sensors provide input to the processing un it.
