A carrier comprising at least one hydraulic cylinder having a piston, a controller and a piston position sensor, wherein the carrier is arranged to carry a tool through the use of the hydraulic cylinder and wherein the controller is configured to: receive control input for moving the tool; receive piston position information for at least one piston of the at least one cylinders; determine a current angle for the tool based on the piston position information; and determine that the current angle approximates a desired angle, and in response thereto halt the tool at the desired angle. According to an aspect the controller may be configured to detect and determine the position of a subject relative the carrier based on hydraulic pressure information and tool operational information. Further, the application concerns methods applied with the embodiments of said carrier.
A carrier comprising at least one hydraulic cylinder having a piston, the carrier further comprising a controller and a piston position sensor, wherein the carrier is arranged to carry a tool via the at least one hydraulic cylinder and wherein the controller is configured to:
