Robot toy

Abstract

A robot toy includes a body and a controller. The body includes right and left arms, legs, arm-actuating mechanisms, thrust mechanisms, and a driving unit. The arms can be extended forward and back, and are pulled back by a predetermined biasing force in a normal condition. The arm-actuating mechanisms provided at the respective arms allow the corresponding arms to be extended in front of the body against the biasing force. The thrust mechanisms provided at the respective legs allow the corresponding legs to move forward. The driving unit drives one of a pair of the left arm-actuating mechanism and the left thrust mechanism and a pair of the right arm-actuating mechanism and the right thrust mechanism. The driving unit simultaneously drives the arm-actuating mechanism and the thrust mechanism in the same pair.

         7 . A robot toy comprising:
 a robot-toy body including a control unit; and   a controller which remotely controls the robot body via the control unit,   wherein the robot-toy body includes:
 right and left arms each connected to a torso, 
   wherein states of each of the right and left arms include a state of being extended forward and being pulled back, and   wherein each of the right and left arms is pulled back by a predetermined biasing force in a normal condition;
 right and left legs each connected to a hip; 
 right and left arm-actuating mechanisms provided at the right and left arms, respectively, 
   wherein each of the arm-actuating mechanisms allows the corresponding arm to be extended in front of the robot-toy body against the biasing force;
 right and left thrust mechanisms provided at the right and left legs, respectively, 
   wherein each of the thrust mechanisms allows the corresponding leg to push against a support so that the leg moves forward; and
 a driving unit which selectively and simultaneously drives a pair of the left arm-actuating mechanism and the left thrust mechanism and a pair of the right arm-actuating mechanism and the right thrust mechanism. 
   
     
     
         8 . The robot toy according to  claim 7 , wherein
 each of the right and left arms includes an upper arm and a lower arm which are bent and stretched with respect to each other;   when the right and left arms are pulled back, the upper arm and the lower arm of each of the right and left arms are bent with respect to each other, so that the robot-toy body assumes a ready position; and   when one of the right and left arms is extended forward, the upper arm and the lower arm of the extended arm are stretched with respect to each other, so that the robot-toy body assumes a punching position.   
     
     
         9 . The robot toy according to  claim 8 , wherein
 each of the thrust mechanisms comprises:
 a lever extending vertically in an interior of the corresponding leg, the lever being supported rotatably with a shaft in the middle of the lever such that a bottom end portion of the lever moves back and forth; 
 a wheel provided at the bottom end portion of the lever; and 
 a clutch mechanism which locks the wheel when the bottom end portion of the lever moves backward, and which releases the wheel when the bottom end portion of the lever moves forward, and wherein 
   a movement of the lever allows the corresponding leg to move forward.   
     
     
         10 . The robot toy according to  claim 9 , wherein
 the driving unit comprises a rotary board which is rotatable about a shaft vertically extending just below the torso, the rotary board including right and left lever-operation touching units corresponding to the right and left levers, respectively; and   when one of the right and left levers is touched by the corresponding lever-operation touching unit, the touched lever moves.   
     
     
         11 . The robot toy according to  claim 10 , wherein
 each of the arm-actuating mechanisms includes a linkage mechanism having a supporting unit which supports the upper arm; the upper arm; the lower arm; and a link disposed between the supporting unit and the lower arm, and wherein one of the upper arm and the link serves as an input link;   the rotary board includes right and left input-link-operation touching units corresponding to the right and left input links, respectively; and   when one of the right and left input links is touched by the corresponding input-link-operation touching unit, the touched input link moves.   
     
     
         12 . The robot toy according to  claim 7 , wherein the predetermined biasing force is the arm's own weight; and
 in the normal condition, the robot-toy body assumes a ready position where each of the right and left arms is bent due to its own weight.   
     
     
         13 . The robot toy according to  claim 8 , wherein
 the predetermined biasing force is the arm's own weight; and   in the normal condition, the robot-toy body assumes a ready position where each of the right and left arms is bent due to its own weight.   
     
     
         14 . The robot toy according to  claim 9 , wherein
 the predetermined biasing force is the arm's own weight; and   in the normal condition, the robot-toy body assumes a ready position where each of the right and left arms is bent due to its own weight.   
     
     
         15 . The robot toy according to  claim 10 , wherein
 the predetermined biasing force is the arm's own weight; and   in the normal condition, the robot-toy body assumes a ready position where each of the right and left arms is bent due to its own weight.   
     
     
         16 . The robot toy according to  claim 11 , wherein
 the predetermined biasing force is the arm's own weight; and   in the normal condition, the robot-toy body assumes a ready position where each of the right and left arms is bent due to its own weight.
