Abstract:
1. An autonomous mobile robot mounted on a track and controllable to move along said track and to selectively stop at one of a series of locations at said track, the autonomous mobile robot comprising: a housing, a front cover covered on a front side of said housing, a rear cover covered on a rear side of said housing, front and rear friction transmission mechanisms respectively mounted on said housing at a top side and protected by a respective side guard, each said friction transmission mechanism comprising a plurality of friction wheels respectively kept in contact with a top surface of a bottom rail of said track, a robot driving motor mounted therein, a friction transmission mechanism driving wheel kept in contact with a bottom surface of said bottom rail of said track, a robot driving motor controllable to rotate said friction transmission mechanism driving wheel for causing the autonomous mobile robot to move along said track, wherein: said housing comprises two upright supports respectively disposed near front and rear sides thereof, a motor roller and a driven roller respectively pivotally connected between said two upright supports at left and right sides in a parallel manner, a first timing pulley fixedly mounted on each of front and rear ends of said motor roller, second timing pulley fixedly mounted on each of front and rear ends of said driven roller, a first timing belt meshed with the first timing pulley at the rear side of said motor roller and the second timing pulley at the rear side of said driven pulley, and a second timing belt meshed with the second timing pulley at the rear side of said motor roller and the second timing pulley at the rear side of said driven pulley so that when said motor roller is started up, said first timing belt and said second timing belt are rotated with said first timing pulleys, causing rotation of said second timing pulleys and said driven roller subject to rotation of said first timing belt and said second timing belt, and therefore said material carrier is moved horizontally leftwards or rightwards by said first timing belt and said second timing belt; said housing further comprises two open spaces respectively defined in two opposite lateral sides thereof, two side covers, two opposing side cover driving motors, two opposing belt pulley holders, each said side cover driving motor comprising a belt pulley fixedly mounted on an output shaft thereof, a belt meshed with the belt pulley of the respective side cover driving motor and a belt pulley at the associating belt pulley holder, connection frames respectively mounted on top and bottom sides of the belts at said side cover driving motors and affixed to top sides of said two side covers by fastening members so that when controlling said side cover driving motors to rotate clockwise or counter-clockwise, the belts at said side cover driving motors are driven to move said connection frames, thereby opening or closing said side covers.
