A humanoid robot including upper limbs, lower limbs, and a trunk. Hip joints which connect the lower limbs and the trunk each possess degrees of freedom provided in correspondence with a hip joint yaw axis, a hip joint roll axis, and a hip joint pitch axis. The humanoid robot is a leg-movement-type robot which walks on two feet. By arbitrarily offsetting the hip joint yaw axes in a roll axis direction, the effects of the movement of the center of gravity occurring when the mode of use of the robot is changed are accommodated to in order to flexibly balance the weights of the upper and lower limbs. The waist is made more compact in order to form a humanoid robot which is well proportioned and which makes it possible to prevent interference between the left and right feet when the direction of a foot is changed. Accordingly, a robot which moves naturally and in a way sufficiently indicative of emotions and feelings using fewer degrees of freedom is provided.

A legged walking robot comprising:
A robot of a type which spreads the legs thereof based on rotational degrees of freedom provided in correspondence with a hip joint roll axis, a hip joint pitch axis, and a hip joint yaw axis, wherein at least the lower limbs and a trunk are mounted substantially vertically along a body axis direction, and wherein the hip yaw axis is offset rearwardly longitudinally from the hip pitch axis by a predetermined amount in the direction of the hip joint roll axis.
A robot of a type which spreads the legs thereof based on rotational degrees of freedom provided in correspondence with a hip joint roll axis, a hip joint pitch axis, and a hip joint yaw axis, wherein at least lower limbs and a trunk are mounted substantially vertically along a body axis direction, and wherein the hip joint yaw axis is offset rearwardly longitudinally from the hip pitch axis by a predetermined amount in a negative roll axis direction of the hip joint roll axis.
A joint device for a robot comprising a plurality of joints, wherein at least rotational degrees of freedom in correspondence with a roll axis, a pitch axis, and a yaw axis are provided, and wherein the yaw axis is offset rearwardly longitudinally from the pitch axis in the direction of the roll axis.
