Abstract: A mobile object control device includes a first controller that recognizes a surrounding situation of a mobile object based on an output of a detection device having a space around the mobile object as a detection range and generates a first movement plan for the mobile object in a first period based on the recognized surrounding situation of the mobile object, and a second controller that generates a second movement plan for the mobile object in a second period shorter than the first period, and when the second controller generates label data in which label information indicating different values depending on at least the presence or absence of a moving object is imparted to each of division elements obtained by dividing the space around the mobile object into a finite number, and generates the second movement plan based on the label data.

Abstract: A control apparatus for performing predetermined control for a predetermined system using reinforcement learning detects an event in a life cycle of the predetermined system and, in response to the detection of the event, set an exploration parameter specified in accordance with the detected event as a value for adjusting a ratio of exploration in the reinforcement learning. The control apparatus executes the predetermined control using the reinforcement learning in accordance with the set exploration parameter. When a first event is detected, the control apparatus sets the exploration parameter so that makes the ratio of the exploration set during a first period after the first event is smaller than the ratio of the exploration set during a second period before the first event is detected.

Abstract: A robot control apparatus causes one or more robots to perform a predetermined task formed by a plurality of task processes. The robot control apparatus includes first control units each configured to control an operation of the one or more robots for each task process of the plurality of task processes, and a second control unit configured to specify a combination and an order to execute the first control units in the plurality of task processes and cause each of the first control units to operate in accordance with the combination and the order.

Abstract: A vibration damping device of an inverted structure includes a cylinder, a rod capable of protruding and retracting in the cylinder, an outer cylinder coupled to the rod and inserted over the outer periphery of the cylinder, and a bush slidably inserted between the outer cylinder and the cylinder. A gap between the outer cylinder and the cylinder is filled with lubricating oil. The bush contains polytetrafluoroethylene and perfluoro alkoxy alkane. The lubricating oil contains an organic molybdenum additive.

Abstract: A damper control system includes a damper control unit which controls a property of a damper used in a suspension of a vehicle; and a processing unit which accepts feedback data pertaining to behavior of the vehicle measured in the vehicle, applies computational processing specified by executing a machine learning algorithm to the feedback data, and outputs a control variable obtained from the computational processing to the damper control unit. The damper control unit controls the property of the damper on the basis of a control variable used internally within the damper control unit, and replaces the control variable used internally with a new control variable. The new control variable is the control variable output by the processing unit.

Abstract: A damper device provided with a single cylinder type erecting structure having a free piston includes: a partition wall fixed to the cylinder between a piston and the free piston and partitioning inside of the cylinder into spaces in an axial direction of the cylinder; a partition wall orifice composed of an orifice piercing through the partition wall; a piston orifice composed of an orifice piercing through the piston; a partition wall-side flow variable structure configured to regulate a flow rate of a viscous fluid passing through the partition wall orifice; a piston-side flow variable structure configured to regulate a flow rate of the viscous fluid passing through the piston orifice; and a control unit configured to control the partition wall-side flow variable structure and the piston-side flow variable structure.

Abstract: A sealing member according to the present invention is a sealing member against a synthetic oil containing an ester-type additive, and includes 95.0% by mass or more and 99.5% by mass or less of a para-phenylen diisocyariate-based polyurethane and 0.5% by mass or more and 5% by mass or less of a same compound as the ester-based additive. The sealing member according to the present invention has a smaller friction coefficient and more excellent deformability than conventional sealing members and that can inhibit swelling caused by a synthetic oil.

Abstract: A variable damping force member is used in a vehicle suspension device and the damping force of which can be changed. The variable damping force member is equipped with a piston which is slidably housed in a cylinder filled with a fluid and which divides the cylinder into a first fluid chamber and a second fluid chamber, and has fluid passages connecting the first and second fluid passages. A valve member is provided in the piston for blocking the fluid passages, and for opening the fluid passages when the piston slides. A piezoelectric body is connected to the valve member, and pushes the valve member towards the fluid passages when voltage is applied. A bellows is arranged on the valve member so as to seal the piezoelectric body from the fluid, and the bellows biases the piston in the direction in which the piezoelectric body is constricted.
