<p>The robot is composed of a figure simulating a boxer which is mounted to a post. A first arm is mounted to the post for pivoting in a vertical plane. A second arm is mounted to a vertical rod mounted within the figure. A prime mover causes the rod to rotate and as it does so, the second arm rotates in a horizontal plane. A roller is connected to the rod and periodically contacts the second arm thereby causing the arm to elevate. Gravity causes the second arm to fall when it is not contacted by the roller. The roller is so positioned to the rod that it causes the second arm to elevate when the first arm is behind the figure and allows the second arm to fall when the first arm is in front of the figure.</p> |
