SYSTEM AND METHOD FOR IMPROVED NAVIGATION OF A ROBOTIC WORK TOOL
A robotic work tool system (200) comprising a boundary (230) enclosing a work area (205) and a robotic work tool (100) comprising a proximity sensor (180) arranged to sense an obstacle (S1, S2, O, B), the robotic work tool (100) being arranged to operate within the work area (205) and the robotic work tool (100) being configured to determine (610) a sensed obstacle (S1, S2, O, B); determine (620) a distance (d); determine (630) whether the distance (d) is inside a threshold distance (D), and if so disregard (640) the proximity sensor (180); and, if not, take (650) evasive action to avoid the sensed obstacle (S1, S2, O, B).
The present disclosure relates to a starter pulley arrangement for an internal combustion engine. The arrangement comprises a cord drum (1) configured to house a starting rope wound thereon, a driver (3) configured to interact with a flywheel (5) or other part connected to an engine crankshaft, and a torsion spring (7) connecting the cord drum (1) to the driver (3), such that the cord drum can resiliently urge the engine crankshaft via the driver. The torsion spring (7) is tensioned in a resting position where the driver does not influence the crankshaft. This provides an improved resistance against wear on the parts of the starter pulley arrangement.
A robotic working tool system (200) comprising a robotic working tool (100) comprising a work tool (160), an attachment receiver (310) arranged to receive an attachment (320) and a controller (110), the controller (110) being configured to receive information regarding an attachment (320) being received, and in response thereto adapt change the operation of the robotic working tool (100) to operate in an attachment operating mode, and to determine an aspect of the attachment (320) and adapt the operation in the attachment operating mode to accommodate for the determined aspect.

A robotic work tool arranged to operate in an operational area bounded by a boundary wire, the operational area encompassing a first charging station and a second charging station, each charging station comprising a base station wire, the robotic work tool comprising a controller, wherein the controller is configured to: operate in the operational area according to a first control signal, the first control signal comprising a first boundary signal being transmitted through the boundary wire and a first base station signal being transmitted through the base station wire of the first charging station; navigate the robotic work tool to locate and move the robotic work tool to the first charging station based on the first control signal; navigate the robotic work tool to distance the robotic work tool from the first charging station in a predetermined manner; synchronize to a second control signal comprising a first boundary signal and a second base station signal both being transmitted through the base station wire of the second charging station; and navigate the robotic work tool to enter the second charging station based on the second control signal.
A cutting tool (100) includes a top blade (102) and a bottom blade (104). The bottom blade (104) is pivotally coupled to the top blade (102). The top blade (102) and the bottom blade (104) together perform a cutting action on an object place between them. A first handle (108) is operatively coupled with the top blade (102). The first handle (108) defines a front portion (109) and a back portion (111). A second handle (110) is operatively coupled with the bottom blade (104). The cutting tool (100) is characterized in that in closed position of the cutting tool (100), at least a part of the second handle (110) at least partially encloses the back portion (111) of the first handle (108).
A hand operated cutting tool (200) for pipes or tubes includes a housing (202). The housing (202) defining at least one first opening (204) to receive an object (210) to perform a first cutting action, and a second opening (206) which is adapted to perform a second cutting action. The first opening (204) includes a longitudinal axis (A-A1) and the second opening (206) include a longitudinal axis (X-X′). The longitudinal axis (A-A1) and the longitudinal axis (X-X′) include an angle (Z) therebetween that is unequal to 0 degree. And, one or more cutting blades (208, 502) are operatively coupled to the first opening (204) and the second opening (206). The one or more cutting blades (208) is arranged such that it is performing both the first cutting action and the second cutting action.
