A walking toy in which if a torso is moved forward walking motion is performed has the torso, two legs. The walking toy includes a crank member having a pair of crank eccentric shafts. Each of the legs has a motion member giving rotational force to the crank member when the torso moves forward. Each of the motion members has an eccentric shaft connecting part pivotably connected to the corresponding crank eccentric shaft, a torso cooperation part, and an action part on which force received from the walking surface act. Projections are formed at the torso cooperation part, while grooves are formed at the torso. If the action part of the one leg moves rearward, the motion member moves to thereby impart rotational force to the crank member and, the other leg is moved forward due to rotation of the crank member, and then contacts the walking surface.

A walking toy includes a body on which gravity center position adjusting members and paired legs are supported to be able to swing in a forward/backward direction, and a gearbox which has a crank mechanism for forcibly swinging the paired legs alternately forward and backward in a forcible swinging direction and which is mounted in the body. Each of the paired legs has a bottom which is configured to be in contact with a floor surface and which is formed into a curved face curved in the forcible swinging direction. The gearbox is driven by a torsion coil spring and has a lever which rotates a drive gear of a gear train for transmitting rotation of the torsion coil spring to an output shaft for rotating the crank mechanism.

A robot apparatus which may be turned to a sound source direction by a spontaneous whole-body concerted operation. With the possible range of rotation of the neck unit of a robot apparatus 1 of ±Y° and with the relative angle of the direction of a sound source S to the front side of the robot apparatus 1 of X°, the entire body trunk unit of the robot apparatus 1 is rotated through (X−Y)°, using the leg units, while the neck joint yaw axis of the robot apparatus is rotated through Y° to the direction of the sound source S, so that the robot apparatus is turned to the direction of the sound source S. If the robot apparatus 1 has found the face of a person already known to the robot apparatus through previous learning and has verified that the person has accosted the apparatus, the body trunk unit is rotated through Y°, at the same time as the neck joint yaw axis is rotated through −Y° to eliminate neck distortion as the apparatus is gazing at the object, so that the apparatus may face the sound source S aright by a spontaneous operation.

It is arranged such that displacement sensors (70) are installed at a position in or vicinity of elastic members (382), to generate outputs indicating a displacement of the floor contact end of a foot (22) relative to a second joint (18, 20), and a floor reaction force acting on the foot is calculated based on the outputs of the displacement sensors by using a model describing a relationship between the displacement and stress generated in the elastic members in response to the displacement, thereby enabling to achieve accurate calculation of the floor reaction force and more stable walking of a legged mobile robot (1). Further, a dual sensory system is constituted by combining different types of detectors, thereby enabling to enhance the detection accuracy. Furthermore, since it self-diagnoses whether abnormality or degradation occurs in the displacement sensors etc. and performs temperature compensation without using a temperature sensor, the detection accuracy can be further enhanced.

The present invention provides a biped (two-footed) walking mobile system, its walk controller, and walk control method therefore, which are to realize enhancing an walk stability, as well as a consumed energy saving. A walk controller (30) of a biped walking mobile system forms a gait data by a gait forming part (33) based on parameters from a gait stabilizing part (32), and drive-controls drive means of respective joint portions (15L, 15R-20L, 20R) of each leg portion based on said gait data. In this case, the walk controller (30) is so constituted as to selectively witch a powered mode to conduct ordinary drive-control and a passive mode to drive-control the drive means similarly with passive joints, whereby drive-controlling respective joint portions. The walk controller (30) preferably switches the drive and passive modes with respect to, for example, joint portions of knee and foot portions, or switches to the powered mode for kick-up and landing during walking motion, and to the passive mode for a free foot state.

A doll includes a body and a head, two legs and two arms, each movably attached to the body. The doll includes a mechanism connected with the head, with each of the legs, and with the arms. The mechanism is configured to displace the legs frontwardly with respect to the body in alternating succession and to displace the head in lateral directions with respect to the body such that the head moves toward one lateral side of the body as one of the legs displaces frontwardly from the opposite lateral side of the body. Movement of the legs displaces the body of the doll in either a walking or a crawling mode. Further, a motor is connected with the mechanism to drive the mechanism to displace the legs, arms and head with respect to the body. An electrical circuit is connected with the motor and has a microphone. The circuit is configured to drive the motor when the microphone receives sound, particularly a user-generated command. Preferably, the circuit includes an integrated circuit chip configured to drive the motor for a randomly specified period of time. The mechanism preferably includes a gear train having an input end connected with the motor and output ends connected with the legs, the arms and the head. Further, the mechanism preferably includes several separate linkages connected with the legs, the arms and the head, each linkage pivoting the associated appendages or the head with respect to the body.

A movement assembly particularly for the legs of a doll comprises a geared transmission whereof the end wheel, supported on the body structure of the doll, has two opposite eccentric pins (48,48'), one for eah leg. On each of the pins a movable U-shoped element (50') is rotatably engaged and is mounted and restrained to the body structure of the doll in order to be driven by the respective eccentric pin in an upward and downward motion and simultaneously an oscillating movement. The U-shaped element has a pin (58) for assembly of the leg, which can be mounted thereon with the possibility of being rotated around the pin.

The mechanism comprises an electric motor 12 capable of rotating in two directions and transmitting rotational movement through an endless belt 14 and two reducer trains 15, 16 to a clutch assembly 17 comprising a center drive wheel 18 and two driven wheels or pinions 19, 20, one on each side, which rotate in a mutually excluding manner depending on the rotational direction of drive wheel 18, its facing side surfaces presenting saw teeth 21, 22 of an appropriate configuration. When the mechanism is activated by removing the pacifier 5 from the doll's mouth, a first phase is executed, consisting in an unsteady walking motion generated by eccentric discs 25 and connecting rods 26, 27; after a specified time has elapsed, this passes on to a second phase consisting in a fall and subsequent upright recovery of the doll, driven by a central wheel 32.
