    摘要： The present invention relates to a method of detecting slip between a self-propelled robotic tool (14) and a grass surface (17), the method comprising the steps of: driving (401) on the grass surface; based on a desired heading and speed (401a) of the self-propelled robotic tool, generating (402) a first drive signal (402a) for a first drive wheel of the self-propelled robotic tool; generating (403) a time-variant drive signal pattern overlay (403a); applying (404) said time-variant drive signal pattern overlay (403a) to said first drive signal (402a) to form a first wheel control signal (404a); operating a first drive wheel based on said first wheel control signal (404a); receiving (406) a movement signal (406a) from a movement detector; and determining (407) a slip state (407a) based on an identification of said time-variant drive signal pattern overlay (403a) in said movement signal (406a).

    摘要： A material collection equipment (100) includes a handle (110) extending along a first axis (A-A') and connected to an implement compartment (120). The implement compartment (120) defines a lower front edge (132) along a second axis (B-B') away from the handle (110). The second axis (B-B') extends transversely relative to the first axis (A-A'). The material collection equipment (100) further includes a pair of wheels (124, 125) rotatably coupled to the implement compartment (120) through a respective axle (114, 115). Each wheel (124, 125) includes a running surface (126, 128). Each wheel (124, 125) defines a spoiler direction (C) from a respective axle (114, 115) towards a mid (127, 129) of the respective running surface (126, 128). The material collection equipment (100) further includes a spoiler (140, 240, 340) coupled to the implement compartment (120) to extend the lower front edge (132) along the spoiler direction (C). The spoiler (140, 240, 340) is disposed adjacent to the lower front edge (132). The spoiler (140, 240, 340) is toollessly adjusted along the spoiler direction (C) relative to the implement compartment (120) in a form-fit manner to extend the lower front edge (132).

    摘要： An electric tool (100) including a first digital control unit, that generates a first digital data signal (108) to be transmitted. The first digital data signal (108) includes operational data of the electric tool (100). The electric tool (100) further includes an interface (106) which further includes at least one light-emitting diode (LED_t) (112) configured to transmit the first digital data signal (108). The at least one light-emitting diode (LED_t) (112) is connected with the first digital control unit in a forward direction, and configured to transmit the first digital data signal (108). The electric tool (100) characterized in that, the interface further includes at least one light-emitting diode (LED_r) (114) configured to receive a second digital data signal (110). The electric tool (100) characterized in that, a second digital control unit which includes a detection circuit for detection of the second digital data signal (110). The at least one light-emitting diode (LED_r) (114) is connected with the second digital control unit in a forward direction.
