Abstract: A vehicle control apparatus includes at least one processor and at least one memory communicably coupled to the processor. The processor sets a target steering angle every predetermined cycle, on the basis of a curvature radius of a first arc passing through a current position of a vehicle, and controls a steering angle on the basis of the target steering angle. The processor sets the target steering angle by obtaining a second arc passing through the current position and tangent to a traveling direction of the vehicle, on the basis of a sum of minimum distances to the first arc from respective target points on a target path. The processor sets the target steering angle in a second cycle following a first cycle, before the vehicle reaches a position corresponding to the farthest one of the target points used for setting of the target steering angle in the first cycle.

Abstract: A vehicle control apparatus includes a processor. Before the vehicle passes through an inflection point of a curvature of a target trajectory, the processor sets a first reference point before the inflection point. After the vehicle passes through the inflection point, the processor sets a second reference point at a position where a second distance from a current position of the vehicle after the vehicle passes through the inflection point to the second reference point is longer than a first distance from a current position of the vehicle before the vehicle passes through the inflection point to the first reference point when compared under travel conditions identical in a vehicle speed, an acceleration rate, a deceleration rate, or a steering angle. The processor sets a target steering angle based on the curvature of an arc passing through the current position and the first reference point or the second reference point.

Abstract: A radio controlled toy in which movement of the toy upon changing the travelling direction is natural and human-like. An upper body is mounted on a seat plate such that the upper body is twisted with respect to the seat plate. Two legs are mounted on the seat plate such that the direction thereof is changed with respect to the seat plate. The upper body and the two legs are interconnected by way of a link mechanism so that a twisting movement of the upper body and a direction changing movement of the two legs is performed in an interlocking relationship with each other. Further, a rotation controlling unit is provided for stopping rotation or reducing the speed of rotation of a wheel provided on an inner side of one of the two legs when a twisting movement of the upper body and a direction changing movement of the two legs are carried out.

Abstract: A toy wheeled vehicle includes an inertial element located so as to move between two positions. A spring is associated with the inertial element to accelerate it from its first position to its second position. When the element reaches its second position the force of the acceleration is transferred to the vehicle chassis and the vehicle chassis "jumps" in response to the force.

Abstract: A moving toy has a plurality of rotating elements located along opposite sides of its body. A motor is connected to these elements via a gear train so as to rotate the elements on the body. A plurality of sets of movable members each are capable of independently being connected to either the rotating elements or to both the rotating elements and the body. Each of the sets of the movable members when connected to the rotating elements are capable of moving the body in a unique manner which differs from the method of movement of any of the other of the sets of the members. The members can include eccentric rolling members, single walking members or compound walking members.

Abstract: A summersaulting toy has a housing with a motor located in the housing. A first and second shaft are located parallel to one another transverse to the longitudinal axis of the toy with the ends of the first and second shafts projecting beyond the right and left sides of the housing. A foot pedestal is attached to right and left sides of both the right and left shafts respectively. In response to rotation of the shafts by the motor, the housing rotates about the shafts such that the housing is rotated first by the foot pedestals on the first shaft as the housing summersaults up and over the first shaft, and then by the pedestals on the second shaft as the housing summersaults up and over the second shaft. This process repeats itself in a cyclic manner as the toy does summersaults across a support surface.
