Embodiments for implementing a harvester method, system, and apparatus are provided. For example, a harvester for produce may include a fluid knife system at a front end of the harvester in a travel direction of the harvester, wherein the fluid knife system projects a fluid at a pressure and a direction that cuts produce, a roller bar including one or more fingers extending radially outward and configured to receive produce from the fluid knife system, wherein the roller bar rotates on its axis turning the one or more fingers at the front end lifting the produce cut by the fluid knife system, a plurality of conveyers that receive the produce from the roller bar and are configured to transport the produce through the harvester, and a bin system configured to receive the produce from the plurality of conveyers and package the produce into one or more bins.

A robotic work tool system (200) comprising a robotic work tool (100) comprising a collision detection sensor (190), said collision detection sensor (190) comprising a first sensor element (191) and a plurality of second sensor elements (192), wherein said first sensor element (191) is movably arranged with respect to said plurality of second sensor elements (192), wherein said robotic work tool (100) is configured to detect that said first sensor element (191) is proximate a peripheral second sensor element (192) and in response thereto determine that a collision has been detected, and detect that said first sensor element (191) is not proximate any peripheral second sensor element (192) and in response thereto determine that a lift has been detected.
