    advancing the machine. Advancing a floor surfacing machine at a normal walking pace would require repeated grinding, which may result in an uneven or generally poor result.
    Releasing the operator of the floor surfacing machine from the actual propulsion of the machine is previously known from EP 1492646 where a remotely controlled floor surfacing machine is described. The operator is there not required to continuously steer the machine, but can concentrate on monitoring the grinding result and if necessary increase or reduce the rate of advance, removing any obstacles or even controlling more than one floor surfacing machine.
    However, for a remotely controlled floor surfacing machine, it is necessary to have a very steady pace without uncontrolled deviations, even for varying frictional forces between the satellite grinding heads and the floor. lt is therefore desired to obtain a remotely controlled floor surfacing machine with enhanced control and stability.
    SUMMARY lt is an object of the present invention to provide a remotely controlled floor surfacing machine with enhanced control and stability.
    Said object is obtained by means of a floor surfacing machine comprising a frame that is carried by at least a first wheel and a second wheel. The floor surfacing machine 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 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.
    According to an example, the floor surfacing machine comprises a handle control panel arranged for control of the operation of the floor surfacing machine. The first control unit may be comprised in the handle control panel.
    According to another example, the first motor may be arranged to propel the planetary head by means of at least one cog-wheel that is attached to a second motor axis and is arranged to engage a circumferentially running driving chain arrangement that is attached to the planetary head.
    According to another example, the planetary head is arranged to be laterally displaced between a leftmost position and a rightmost position in an oscillating manner.
    A number of advantages are provided by means of the present invention, mainly increased stability, control and productivity. Furthermore, having a planetary head and satellite surfacing heads that are independently operable may require a large force to control for an operator, which is alleviated by means of the present invention where remote control is combined with having a planetary head and satellite surfacing heads that are independently operable.
    BRIEF DESCRIPTION OF THE DRAWINGS The present invention will now be described more in detail with reference to the appended drawings, where: Figure 1 shows a top view of a floor surfacing machine; Figure 2 shows a side view of a floor surfacing machine; Figure 3 shows a remote control panel; Figure 4 shows a bottom perspective view of the planetary head; Figure 5 shows a top perspective view of the planetary head; and Figure 6 shows a top view of a floor surfacing machine with an oscillating feature.
    DETAILED DESCRIPTION Figure 1 and Figure 2 show a top and a side view of a floor surfacing machine 1, for example a floor grinding or polishing machine. The floor surfacing machine 1 has a frame 2 that is carried by a first wheel 3 and a second wheel 4. The frame 2 comprises a motor mounting plate 5 and a handle arrangement 7 allowing an operator to move the machine over a floor surface 8 to be surfaced. The surfacing machine comprises a first motor 6 that is mounted to the frame 2. The handle arrangement 7 comprises a handle control panel 9 for control of the operation of the floor surfacing machine 1, where the handle control panel 9 in turn comprises a first control unit 10.
    With reference also to Figure 3, the floor surfacing machine 1 further comprises a remote control panel 11 which in turn comprises a second control unit 12 that is arranged to communicate with the first control unit 10 by means of radio signals. The remote control panel corresponds to the handle control panel 9, allowing an operator to remotely run the floor surfacing machine 1.
    When remotely controlling the floor surfacing machine 1, an operator should then be positioned having a good, clear view of the floor surfacing machine 1 and floor surface 8 that is to be treated, either by being in the vicinity, or by being at a remote location where the floor surfacing machine and floor surface that is to be treated may be studied via a viewing screen or monitor of some suitable kind. An operator is then not required to continuously steer the floor surfacing machine 1, but can concentrate on monitoring the surfacing result and if necessary increase or reduce the rate of advance, removing any obstacles or even controlling more than one floor surfacing machine.
    Whenever appropriate, an operator is naturally able to control and steer the floor surfacing machine 1 by means of the handle control panel 9 and the handle arrangement 7 in the conventional way, manually guiding the floor surfacing machine 1. lt will now be described more in detail which motors and mechanisms that are controlled at the floor surfacing machine 1.
    A first wheel drive motor 13 and a second wheel drive motor 14 is mechanically connected to the corresponding first wheel 3 and second wheel 4, and also electrically connected to the to the first control unit 10. The first control unit 10 comprises means for controlling the wheel drive motors 13, 14 individually and hence the direction of rotation and the rotational speed of each wheel 3, 4 as a function of control signals from any one of the control panels 9, 11 which is manually actuated by an operator. In this way, it is possible to steer the floor surfacing machine 1 by means of affecting the wheel drive motors 13, 14 individually, either by means of the handle control panel 9 or the remote control panel 11.
    The floor surfacing machine 1 further comprises a planetary head 15 which is rotatably mounted to the frame 2, and comprises a cylindrical wall 16 closed at both ends by a top plate 17 and bottom plate 18, where the motor mounting plate 5 is mounted above the planetary head 15. The first motor 6 is arranged to drive the planetary head 15.
    With reference also to Figure 4, showing a bottom perspective view of the planetary head 15, the Oor surfacing machine further comprises three satellite surfacing heads 19, 20, 21 that are rotatably mounted within the circumference of the planetary head, where the satellite surfacing heads 19, 20, 21 are adapted for treating the floor surface 8 by means of for example grinding or polishing. The According to the present invention, the floor surfacing machine 1 further comprises a second motor 22 that is mounted to the motor mounting plate 5, where the second motor 22 is arranged to drive the satellite surfacing heads 19, 20, 21, such that the planetary head 15 and the satellite surfacing heads 19, 20, 21 are independently operable.
    The first motor 6 and the second motor 22 operate entirely independently, and as a result, the satellite surfacing heads 19, 20, 21 and planetary head 15 are driven independently, and can be driven in a mutually opposing direction of rotation or in the same direction of rotation, and can be driven at different speeds independently of one another.
    Opposite direction of rotation create less friction on the satellite surfacing heads 19,, 21, delivering less powerful surfacing effect and easier handling. When the floor surfacing machine 1 is moved fon / vard, a “middle zone” of the surfacing path is ground more thoroughly (twice) than “outer zones” of the surfacing path. The end result is a deeper cut through the “middle zone” and a shallower cut in the “outer zones.” Lt is a direct result of where the satellite surfacing heads 19, 20, 21 have been spending their time.
    Having the same direction of rotation creates more friction on the satellite surfacing heads 19, 20, 21, delivering wider width of surfacing effect and higher productivity.
    When the floor surfacing machine 1 is moved forward, the “middle zone” is still ground more thoroughly than the “outer zones”, but not as much as in the case of counter rotation. The end result is still a deeper cut through the “middle zone” when compared to the “outer zones”, but it is less pronounced than in counter rotation.
    This allows an operator to, for example, drive the planetary head 15 at a relatively low rate over a rough floor surface so that the floor surfacing machine 1 does not bounce when it strikes rough patches but still drives the satellite surfacing heads 19,, 21 at relatively high speed so as to maintain production capacity of the floor surfacing machine 1. lf the floor surface 8 is to be only lightly finished, for example polished, the planetary head 15 may be driven quickly so that the floor surfacing machine 1 covers the floor surface 8 at a rapid rate and the satellite surfacing heads 19, 20, 21 remain in contact with any given portion of the floor surface 8 for only a relatively short time.
    This provides the floor surfacing machine 1 according to the present invention with considerable Exibility in its applications.
    The inventors have realized that for a remotely controllable floor surfacing machine 1, it is highly advantageous to have independently driven satellite surfacing heads 19,, 21 and planetary head 15 as described above, sine this enables an enhanced control, stability and productivity for a remotely controlled floor surfacing machine 1 compared to prior art.
    Furthermore, having a planetary head and satellite surfacing heads that are independently operable may require a large force to control for an operator, which is alleviated by means of the present invention where remote control is combined with having a planetary head and satellite surfacing heads that are independently operable.
    The combination of remote control and independently driven satellite surfacing heads 19, 20, 21 and planetary head 15 thus provides a plurality of advantages.
    The second control unit 12 may be arranged to communicate with the first control unit by means of other means than radio signals, for example optical or sonic signals. In the following, an example of how the planetary head 15 and the satellite surfacing heads 19, 20, 21 are propelled by means of the first motor 6 and the second motor 22 will now be described more in detail with reference to Figure 4 and Figure 5, where Figure 5 shows a perspective top view of the planetary head 15.
    With reference to Figure 4, the second motor 22 (not shown in Figure 4) is connected to a first motor axis 23 that extends through the top plate 17 and the bottom plate 18, and is connected to a first belt pulley 24 that is arranged to drive an endless belt 25 that further is guided by means of a second belt pulley 26, a third belt pulley 27, a fourth belt pulley 28 and a fifth belt pulley 29. Each of the second belt pulley 26, third belt pulley 27, the fourth belt pulley 28 and the fifth belt pulley 29 is rotatably connected to the bottom plate 18, and is arranged to guide the endless belt 25 around the satellite surfacing heads 19, 20, 21 such that they are propelled when the second motor 22 drives the endless belt 25.
    The fifth belt pulley 29 is attached to the bottom plate 18 via tensioning device 30 that is arranged to press the fifth belt pulley 29 against the endless belt 25 with a certain force, for example by means of a spring arrangement (not shown). ln the way, the endless belt 25 is tightened around the belt pulleys 24, 26, 27, 28, 29 and the satellite surfacing heads 19, 20, 21 to a certain extent that suitably is adjustable by means of the tensioning device 30. The tensioning device 30 should also be releasable such that the endless belt 25 is untightened, for example if the endless belt 25 needs to be replaced.
    As shown in Figure 5, the first motor 6 is connected to a gear-box 31 from which a second motor axis (not shown) extends. Two driving cog-wheels 32, 33 are attached to the second motor axis. Furthermore, the planetary head 15 comprises a circumferentially running top rim 34 that is mounted to the top plate 17. On the inner side of the rim top 34, a driving chain arrangement 35 is attached. The driving chain arrangement 35 is arranged to engage the driving cog-wheels 32, 33 such that when the driving cog-wheels 32, 33 are propelled by means of the first motor 6, these rotate the chain arrangement 35 which in turn rotate the planetary head 15 to which it is attached via the top rim 34.
    The above are only examples of how the planetary head 15 and the satellite surfacing heads 19, 20, 21 are propelled by means of the first motor 6 and the second motor 22, many other types of transmission arrangements are of course conceivable. For example, the first motor 6 may be arranged to propel the planetary head 15 by means of an endless belt that runs around the outer surface of the top rim, where the endless belt is connected to the first motor 6 by means of a pulley transmission arrangement (not shown).
    The positions of the first motor 6 and the second motor 22 may be altered in dependence of how they are arranged to propel the planetary head 15 and the satellite surfacing heads 19, 20, 21.
    With reference to Figure 6, showing a further example, the floor surfacing machine 1 is equipped with an oscillating feature that widens the surfacing width. The planetary head 15 is then arranged to be laterally displaced from a normal position where the center of the planetary head 15 intersects a first line 36 that runs through the surfacing machine in its longitudinal direction. The displacement runs between a leftmost position where a first angle oi is formed between the first line 36 and a second line 37 that intersects the center of the planetary head 15, and a rightmost position where a second angle ß is formed between the first line 36 and a third line 38 that intersects the center of the planetary head 15. The second line 37 and the third line 38 also intersect each other and the first line 36 at a certain point in the floor surfacing machine 1.
    When the planet head 15 oscillates between the leftmost position and rightmost position, an increased surfacing width 39 is obtained. Furthermore, a more lenient surfacing is obtained. The first angle d and the second angle ß, which angles d, ß might be equal, are adjustable, as well as the oscillating rate. The adjustment may of course be made by means of the remote control panel 11.
    The invention is not limited to the above, but may vary freely within the scope of the dependent claims. For example, the satellite heads may be arranged for any suitable type of surfacing; being equipped for grinding or polishing. The number of satellite heads may vary, but there should be at least one. The number of wheels 3, 4 may vary, but there are at least two wheels.
