Abstract: An illuminance sensor detects a flicker with higher accuracy than in the related art. The illuminance sensor includes: a light receiving unit that receives light and outputs a current; a flicker measurement counter circuit that performs AD conversion on the current and outputs a first digital signal to a flicker measurement storage device; an illuminance measurement counter circuit that performs AD conversion on the current and outputs a second digital signal to an illuminance measurement storage device; and a flicker detection unit that detects a flicker by analyzing the first digital signal stored in the flicker measurement storage device. A cycle during which the first digital signal is output from the flicker measurement counter circuit is shorter than a cycle during which the second digital signal is output from the illuminance measurement counter circuit.

Abstract: A light receiver capable of detecting the intensity of light in a certain wavelength range is provided. The light receiver includes a first light receiving element (PD1) and a second light receiving element (PD2) that have an identical spectral sensitivity characteristic, and a UV cut filter (11). Light that has passed through the UV cut filter (11) enters the first light receiving element (PD1). A subtractor is provided that calculates a difference between a photocurrent of the first light receiving element (PD1) and a photocurrent of the second light receiving element (PD2).

Abstract: Provided is a robot which allows a user to set a parameter, instead of separately providing any specific input section via which the parameter is set. A robot (1) includes (i) a right arm part, (ii) a servomotor, that is a right shoulder pitch, which is configured to drive the right arm part, (iii) an obtaining section (105) which is configured to obtain positional information on a position. of the right arm part which has been operated and (iv) a setting section (107) which is configured to set a value of a predetermined parameter to a value corresponding to the positional information that is obtained by the obtaining section (105).

Abstract: Provision of a robot which has a simpler configuration and is capable of a stand-up operation. A posture controlling section (10) changes a posture of a robot 1 from a sitting posture to a bridge posture. In the bridge posture, a projected point (T), which represents a center of gravity of the robot (1) projected onto a plane parallel to a support polygon (R) of the robot (1), is at a position that is outside the support polygon (R) and near a right leg part 6 and a left leg part 7.

Abstract: A directional characteristic of light that is incident on a light-receiving unit is adjusted in accordance with whether a proximity-illumination sensor is caused to act as a proximity sensor or to act as an illumination sensor. The proximity-illumination sensor (50) includes a light-receiving area selection unit (101) that selects light-receiving sensitivity of which of a first light-receiving area and a second light-receiving area is made higher in accordance with whether the proximity-illumination sensor (50) is caused to act as the proximity sensor or to act as the illumination sensor.
