Biped robot
First Claim
1. A biped robot having at least a body, two leg linkages each swingably connected to the body through hip joints, and two arm linkages each swingably connected to the body through shoulder joints, such that said robot walks over a floor surface in an operating space by swinging the leg linkages and performs operations on objects in the operating space by driving at least the arm linkages,characterized in that:
- a height from ends of the leg linkages, that contact the floor surface, to the shoulder joints, when the robot is in an upright posture is determined to be a value that falls within a range of averaged value Havg, of heights of the objects from the floor surface, ±
½
a standard deviation σ
of the averaged value.

Abstract
The height from floor surface contact ends of leg linkages 2 to shoulder joints of a biped robot 1 when the biped robot is in an upright posture is defined to be a value falling within a range (Havg±½σ) set based on an averaged value Havg obtained by averaging the heights of a group of objects (subject to operation) from the floor surface and the standard deviation σ thereof, specifically a value in a range of from approximately 700 mm to 1000 mm. By this, the installation height of shoulder joints from the floor surface can be optimally determined in accordance with the heights of the objects, thereby improving operating efficiency in an existing operating space.

5. A biped robot having at least a body, two leg linkages each swingably connected to the body through hip joints, two arm linkages each swingably connected to the body through shoulder joints and equipped with hands at their extremities, and a head swingably connected to the body through a neck joint and installed with a visual sensor composed of an imaging device, such that said robot walks over a floor surface in an operating space by swinging the leg linkages and performs operations on objects in the operating space by driving the arm linkages based on at least information on the operating space obtained from imagery taken by the imaging device,
characterized in that: the imaging device is installed such that optical axes connecting the hands and the imaging device make angles within a range of from 5 degrees to 45 degrees with respect to the horizontal direction when the arm linkages are positioned in a horizontal direction parallel to the floor surface when the robot in an upright posture. - View Dependent Claims (6)
