Abstract

A floor cleaning or burnishing machine has at least one motor controller electrically connected to a pointing device control, right and left software driven motor control logic units, an electrical power source, and right and left electrical drive motors. These motors are mechanically connected to respective rear steering drive wheels. Rotational speed and direction of each rear wheel is independently controlled, using the pointing device in cooperation with respective control logic units, in either a forward or reverse direction. At any given time, each control logic unit controls a respective motor controller which individually controls the rotational speed and direction of a respective wheel, thereby each wheel is capable of rotating in an opposite direction at a different speed to the other wheel. To slow the machine down, regenerative braking is utilized by operating the motors as generators.

Claims

1. A floor cleaning or burnishing machine, comprising:

a pointing device control;

a pointing device selected from the group consisting of a mouse, a stylus with a touch screen, control buttons and a scroll wheel, a tablet with a virtual keyboard, a trackball, a hand held remote control ring, a light pen, a Google glass, a wireless RF device, a laptop computer with keyboard, a touch pad cell phone, a button direction device, and a blue tooth wireless mouse, wherein the pointing device is controlled by the pointing device control;

a right motor control logic unit controlled by the pointing device control and having three right communication lines and a left motor control unit having three left communication lines;

at least one motor controller electrically powered by an onboard electrical power source and separately in electrical communications with the three right communication lines and the three left communication lines;

a right electrical motor in mechanical communication with a right mechanical linkage and a left electrical motor in mechanical communication with a left mechanical linkage; and

a right rear steering drive wheel mechanically driven by the right mechanical linkage and a left rear steering drive wheel being separately mechanically driven by the left mechanical linkage;

wherein rotational speed and forward and reverse direction of the right rear steering drive wheel is independent of the rotational speed and forward and reverse direction of left rear drive wheel, on a floor to be cleaned.

2. The floor cleaning machine or burnishing machine of claim 1, wherein the at least one motor controller comprises a separate right motor controller being individually electrically connected to the right motor control logic unit and further comprises a separate left motor controller being individually electrically connected to the left motor control logic unit.

3. The floor cleaning machine or burnishing machine of claim 2, wherein each of the right and left motor controllers comprises a processor electrically connected internally to a MOSFET driver that in turn is electrically connected internally to a MOSFET bridge circuit that in turn is electrically connected externally to the respective right and left electrical drive motor.

4. The floor cleaning machine or burnishing machine of claim 1, wherein the pointing device has an ST position where each of the right and left electrical drive motors are a regenerative brake and the pointing device has any other position where the right and left electrical drive motors are rotationally mechanically connected to their respective rear steering drive wheel.

5. The floor cleaning machine or burnishing machine of claim 1, wherein each of the right and left mechanical linkages comprises a belt drive and pulley.

6. The floor cleaning machine or burnishing machine of claim 1, wherein each of the right and left mechanical linkages comprises a direct drive mechanism.

7. The floor cleaning machine or burnishing machine of claim 1, wherein each rear steering drive wheel is capable of being in the other rear wheel position after a 180 degree turn.

8. The floor cleaning machine or burnishing machine of claim 1, wherein each of the rear steering drive wheels is capable of remaining in a pivot position.

9. The floor cleaning machine or burnishing machine of claim 1, wherein the pointing device is in remote robotic computer communication with a floor cleaning/burnishing machine.

10. The floor cleaning machine or burnishing machine of claim 1, wherein the right motor control logic unit is logically controlled by software having a right (RGT) portion and a left (LFT) portion and the left motor logic unit is logically controlled by software having a forward (FWD) portion and a reverse (REV) portion.
