Floor surfacing machine
First Claim
1. A floor surfacing machine comprising:
- a frame that is carried by at least a first wheel and a second wheel,at least one operating head that is rotatably mounted to the frame,a control unit, anda wheel drive assembly for individually controlling the first wheel and the second wheel,wherein the control unit is arranged to add an oscillation control signal to a wheel drive control signal to individually vary a speed of the first wheel in relation to a speed of the second wheel to generate self-oscillation of the operating head to laterally displace the operating head between a leftmost position and a rightmost position in an oscillating manner based on the oscillation control signal such that an increased surfacing width is obtained.

Abstract
The present invention relates to a floor surfacing machine comprising a frame that is carried by a first wheel and a second wheel. The floor surfacing machine further comprises a first motor, a handle arrangement, at least one planetary head that is rotatably mounted to the frame and at least one satellite surfacing head that is rotatably mounted to the planetary head, where the first motor is arranged to propel the planetary head. The floor surfacing machine comprises a first control unit, and a remote control panel which in turn comprises a second control unit) that is arranged to communicate with the first control unit. The floor surfacing machine also comprises a second motor that is arranged to propel the satellite surfacing heads such that the planetary head and the satellite surfacing heads are independently operable.

2. A floor surfacing machine comprising:
-
a frame that is carried by at least a first wheel and a second wheel, at least one operating head that is rotatably mounted to the frame, a control unit, and a wheel drive assembly for individually controlling the first wheel and the second wheel, wherein the control unit is arranged to add an oscillation control signal to a wheel drive control signal to individually vary a speed of the first wheel in relation to the second wheel for laterally displacing the operating head between a leftmost position and a rightmost position in an oscillating manner such that an increased surfacing width is obtained, and wherein the control unit is arranged to determine that a surface being serviced presents uneven surfacing conditions and in response thereto;
adjust the oscillation control signal so that the floor surfacing machine spends more time on one side, or to adjust an outermost position on one side so that the floor surfacing machine turns more to that side. - View Dependent Claims (8, 10, 12)

3. A floor surfacing machine comprising:
-
a frame that is carried by at least a first wheel and a second wheel, at least one operating head that is rotatably mounted to the frame, a control unit, and a wheel drive assembly for individually controlling the first wheel and the second wheel, wherein the control unit is arranged to add an oscillation control signal to a wheel drive control signal to individually vary a speed of the first wheel in relation to the second wheel for laterally displacing the operating head between a leftmost position and a rightmost position in an oscillating manner such that an increased surfacing width is obtained, and wherein the control unit is arranged to determine that a wheel is rotating at a higher than expected rate and to thereby reduce the speed of the rotating wheel, reduce the speed of the other wheel, or increase the speed of the other wheel if the other wheel is rotating in a direction different from a direction of rotation of the rotating wheel. - View Dependent Claims (9, 11, 13)
