Abstract: A light receiver 212u provided on the upper side and a light receiver 212d provided on the lower side with respect to the optical axis of a light emitter 211 generate light reception signals corresponding to the light reception intensity of emitted light from the light emitter 211. A liquid level state determiner 30 determines a liquid level state on the basis of a signal level difference between the light reception signal generated by the light receiver 212u and the light reception signal generated by the light receiver 212d. It is not required to perform processing of captured image data, and even in a case where a liquid temperature is substantially equal to the outside air temperature, the state of a liquid level can be easily grasped.

Abstract: An actuator capable of achieving high output with a smaller number of parts is proposed. An actuator including a stator that has teeth arranged on an outer peripheral surface, a rotor that rotates around a central axis of the stator while teeth arranged on an outer peripheral surface mesh with the teeth arranged on the outer peripheral surface of the stator, and a second gear that rotates while meshing with a first gear coupled to the rotor coaxially with a central axis of the rotor and is coupled to an output shaft, in which the stator has an electromagnet, the rotor has a magnet, and a magnetic pole of the electromagnet corresponding to a position of the rotor moves along a circumferential direction of the stator.

Abstract: Provided is an actuator that achieves a high energy efficiency at a low speed while having a compact configuration. The actuator includes a stator and a rotor. The stator has a disk, a pillar including a permanent magnet, and a coil wound around the pillar. The rotor is provided movably along an outer edge of the disk with the rotor being in contact with the outer edge of the disk. The coil is configured to form, through energization of the coil, a magnetic circuit that passes through the disk, the pillar, and the rotor. The disk includes a first part and a second part that are disposed alternately along the outer edge of the disk, in which the first part has a first magnetic permeability and the second part has a second magnetic permeability that is higher than the first magnetic permeability.

Abstract: The present technology relates to an information processing device, an information processing method, and a program capable of generating a trajectory with smoother movement and/or shorter path based on the trajectories generated by a global trajectory planning. The information processing device includes: a first processing unit that executes a collision avoidance optimization process of searching for a path that collides with an obstacle using N postures corresponding to input trajectories of a machine; and a second processing unit that sets a target value of each of the N postures to an intermediate position between two postures before and after a current posture and executes the collision avoidance optimization process. The present technology can be applied to, for example, control of a type of robot called a manipulator.
