Abstract: A robot joint including a first part and a second part arranged to have a relative movement in between, and a joint gap spacing the first part and the second part from each other, wherein the robot joint includes an inflatable seal accommodated in the joint gap to provide a fluid-tight sealing of the joint. The disclosure also relates to a robot including the robot joint, a system including the robot and a method for sealing a joint gap of a robot joint.

Abstract: An apparatus, method and computer program for controlling propulsion of marine vessel. The propulsion is implemented by a foil wheel propulsion system. The method includes: receiving a wheel operation status from a wheel drive; receiving a plurality of foil operation statuses from a plurality of foil drives; receiving a command from a vessel control system; generating wheel control data for the wheel drive to control a foil pitch function of the foil wheel propulsion system based on the command in view of the wheel operation status; and generating foil control data for the plurality of the foil drives to further control the foil pitch function of the foil wheel propulsion system based on the command in view of the wheel operation status and the plurality of foil operation statuses, wherein a reference torque of the foil control data for each foil drive is generated using a foil feedforward model.

Abstract: A robot joint including a first robot part and a second robot part arranged to have a relative movement in between, a joint gap separating the first robot part and the second robot part from each other, and a seal arrangement for sealing the joint gap against external impact. The seal arrangement includes a first side element being part of the first robot part and immobile in relation to the same, and a gap element extending across the joint gap. One of the first side element and the gap element includes a first surface in a food grade material, and the other one of the first side element and the gap element includes a first sealing element configured to be in sliding contact with the first surface.
