  • Patent number: 8265774
    Abstract: An inverted pendulum type moving body according to the present invention includes: first actuators that rotationally drive wheels each disposed on an axle; and a turning motion control portion that controls the first actuators when the inverted pendulum type moving body comes into contact with an obstacle so as to allow the inverted pendulum type moving body to perform a turning motion.
    Type: Grant

  • Patent number: 8011459
    Abstract: To provide an inverted wheel type moving body capable of improving the operability, and a method of controlling the same. An inverted wheel type moving body in accordance with one aspect of the present invention includes motors 34 and 36 for rotationally driving a right driving wheel 18 and a left driving wheel 20 respectively, a passenger seat 74 rotationally supported on mounts 26 and 28 through swing arms 17 and 19, a passenger seat drive motor 70 for driving the passenger seat 74, a control portion 80 for determining whether the manipulation amount exceeds the threshold value or not, and a motor driver 70a for control the passenger seat drive motor 70 such that the passenger seat 74 is moved in accordance with the manipulation amount when the manipulation amount does not exceed the threshold value and the movement of the passenger seat 74 is restored after the manipulation amount exceeds the threshold value.
