Latest Patents

Among Okada’s latest inventions is a groundbreaking knee joint designed to widen the moveable range while prioritizing energy efficiency. This knee joint is characterized by its compact and lightweight design, making it an attractive option for various applications. Additionally, it features an active type mechanism that remains comparatively inexpensive. The design utilizes a drive section that moves a driven member, with an elastic member positioned between this driven member and a linear motion member. This configuration allows the linear motion member to elastically move in one direction based on the driven member’s movement. Furthermore, a crank mechanism effectively translates the linear motion into rotational motion, thus enabling bending and extension of the knee joint.

Another notable patent focuses on the development of a device and method for estimating the potential existence region of a specific state quantity in mobile robots. This invention employs an arithmetic processing unit to carry out polyhedron projection processing, seeking to identify a projection region derived from a convex polyhedron within a space defined by the contact reaction forces of multiple points on a mobile robot. The convex polyhedron is characterized by mechanical relations between the contact reaction forces and the specific state quantity, alongside linear inequalities that outline constraint conditions for contact reaction forces.
