Latest Patents

Haikawa's latest patents include a method of generating the gait of a legged walking robot. This innovative method involves a two-legged walking robot that has articulated legs connected to a body through hip joints. The robot is designed to drive its legs in a manner that allows it to walk in a specific direction by estimating the position of its body when the hind leg kicks the ground. The method also determines the amount of lift needed for the heel of the hind leg to ensure the robot reaches the estimated position. Additionally, the vertical amplitude of the robot's trajectory is adjusted to achieve the desired vertical acceleration, ultimately controlling the robot's locomotion based on the generated gait.

Another significant patent is a navigation control system for mobile robots. This system focuses on current position recognition for biped walking robots within a navigation environment. A pre-prepared map of the environment includes designated shape features of objects, such as stairs. The robot utilizes a vision sensor to recognize its current position based on these shape features. The system also establishes evaluation functions to select the most relevant shape features, allowing the robot to navigate effectively along a predesignated path.
