Abstract: In a running device for a model (6) comprising a pair of motors (7), a pair of left and right wheels (8) which are independently driven by the pair of motors (7), and a control device (20) which controls operations of the pair of motors (7) based on instructions concerning speed and direction, the control device (20) controls the pair of motors (7) such that the pair of motors (7) are alternately rotated in an instructed direction when the instructed speed (Vm) is in a low speed range (L, M), and the pair of motors (7) are rotated in the instructed direction simultaneously when the instructed speed is in a high speed range (H) which is higher than the low speed range.

Abstract: A driving device (2) which is remotely controlled by a transmitter (1) holds a first parameter (D) and a second parameter (L), transmits an offense signal based on the first parameter (D), and changes the second parameter (L) according to information included in a received specified signal. A remote control system can realize a battle game where the transmitter (1) and the driving device (2) play against another pair of a driving device (2) and a transmitter (1), the driving device (2) receives the offense signal transmitted from the other driving device (2) as the specified signal, and the second parameter (L) is changed according to the information included in the specified signal can be realized in a remote control toy system. In the system, the transmitter (1) allows a control signal to include specified information according to a user's specified operation, and the driving device (2) changes the its own first parameter (D) based on the specified information in the control signal.

Abstract: The present invention provides a play extension system enhancing a fun of a toy system by use of network. The play extension system is used by combination with the toy system in which a user can change the setting of parameters affecting motion control of a driving machine, for extending a playing method with the toy system. In the system, the setting information corresponding to the setting state of the parameters is received from a predetermined user terminal through a network, and estimation on the obtained setting information is created by referring to a database which stores the setting information and the information for estimating the setting state correspondingly. The created estimation is transmitted to a predetermined destination through the network.
