Latest Patents

Ezawa's latest patents include innovative designs for manipulators. One notable patent describes a manipulator that improves economic efficiency and reliability by reducing the size and weight of the system. This is achieved through a backup mechanism that utilizes a common specification drive circuit and actuator when a fault occurs. The design allows the actuator of the end effector to share a common structure with the actuators of multiple joints, driven by a unified drive unit. Additionally, the actuator features two switchable systems and a spare drive unit.

Another significant patent outlines a manipulator with six degrees of freedom, equipped with a force sensor. This manipulator is controlled by calculating the forces and moments applied to its regions based on the sensor's output. When excessive force or moment is detected, the joint experiencing the highest load is halted to conserve energy. Alternatively, the joint can be driven in a direction that reduces the load, preventing damage to the manipulator's regions. This design allows for optimal strength and size reduction in the manipulator.
