Abstract: According an embodiment, a work support device includes an arm unit, a brake unit, a state determination unit, and a brake control unit. The arm unit includes a grasping part configured to grasp an object, a plurality of joint parts, and a plurality of link parts actuatably coupled through each joint part. The brake unit is provided to at least one of the joint parts to restrict actuation of the arm unit. The state determination unit determines the state of the arm unit. The brake control unit controls the brake unit to restrict actuation of the arm unit in accordance with the state of the arm unit.

Abstract: According to an embodiment, a transport device includes: a vehicle body including a fork portion that supports a load, a lift portion that drives the fork portion up and down, a movable carriage portion that supports the lift portion, and is movable on a traveling surface by driving a drive wheel, and an auxiliary leg portion that is provided in the movable carriage portion, is movable along a longitudinal direction of the fork portion, and has an auxiliary wheel having a variable position with respect to the movable carriage portion; and a control unit that, in a case where a step is present on the traveling surface, controls operations of the lift portion, the movable carriage portion, and the auxiliary leg portion such that the movable carriage portion climbs the step, based on the position of the center of gravity calculated by a calculation unit.

Abstract: According to an embodiment, a work support device includes a measurement unit and an irradiation control unit. The measurement unit measures an in-passage structure of a passage inside of which a user can work. The irradiation control unit controls an irradiation unit to emit light indicative of a work region to a corrected work position obtained by correcting work position information set based on a predetermined designed in-passage structure indicative of an ideal structure in the passage by using a result of the measurement by the measurement unit.
