Abstract:
1. An autonomous mobile robot mounted on a track and controllable to move along said track and to stop at a selected location 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 therein two upright supports respectively disposed near front and rear sides thereof, a plurality of conveying rods pivotally connected between said two upright supports in a parallel manner, a plurality of friction wheels respectively fixedly mounted on said conveying rods, a plurality of transmission gears respectively fixedly mounted on one end of each of said conveying rods, a plurality of driven gears respectively pivotally mounted on one said upright support and respectively meshed with said transmission gears, a driving gear meshed with two middle ones of said driven gears and affixed to a motor shaft of a carrier driving motor that is controllable to rotate said driving gear clockwise/counter-clockwise for enabling said driven gears to be driven to rotate said transmission gears and said conveying rods so that when a material carrier is placed on said friction wheels at said conveying rods, said friction wheels are rotatable with said conveying rods clockwise/counter-clockwise to move said material carrier horizontally leftwards/rightwards, two open spaces defining in two opposite lateral sides thereof, two side covers pivotally mounted on the two opposite lateral sides and adapted to close/open said open spaces, two side cover driving motors respectively mounted therein, two pinions respectively fixedly mounted on a respective output shaft of each of said side cover driving motors, two sector gears respectively fixedly mounted on said side covers and respectively meshed with said pinions such that when controlling said side cover driving motors to rotate clockwise/counter-clockwise, said sector gears are driven by said pinions to bias said side covers upwards/downwards and to further open/close said open spaces.
