Abstract

To provide a robot whose degree of freedom of design is not limited, and which has simple structure and further reduces load of an actuator of a neck part, the present invention provides a robot at least including a head part, a body part, and a neck link which connects the head part and the body part, wherein a surrounding object distance measurement means is provided adjacently to the neck link and in an upper portion of the body part between the head part and the body part, and a distance scanning field of the surrounding object distance measurement means is provided in parallel with a horizontal plane.

Claims

1. A robot comprising a head part attached to an upper central portion of a body part via a neck link, and a head actuator for moving the head part, wherein

a laser scanning range sensor is provided adjacently to the neck link and in the center of a top of the body part, a scanning plane of the laser scanning range sensor being in parallel with a horizontal plane, and

a distance l₁ between a top surface of the laser scanning range sensor and an output shaft of the head actuator, and a distance R₁ between the output shaft of the head actuator and the most distant point of a face constituting the head part from the output shaft of the head actuator are set to satisfy the relationship of l₁>

R₁.

2. The robot according to claim 1, comprising two said laser scanning range sensors arranged in the center of the top of the body part.
