Title: Sadao Kawamura: Innovator in Force Detection and Robotics
Introduction
Sadao Kawamura is a notable inventor based in Shiga, Japan. He has made significant contributions to the fields of force detection and robotics, holding a total of 2 patents. His innovative work has implications for various applications in technology and automation.
Latest Patents
Kawamura's latest patents include a force detector and a robot control apparatus. The force detector comprises a support, fluid bags, a contact portion, a detector, and a computer. The computer obtains information regarding the internal pressures of the fluid bags from the detector. Upon application of an external force to the contact portion from an object, the computer calculates a force acting in a tangential direction on a contact surface based on the difference between the internal pressures of the fluid bags.
The robot control apparatus patent describes a system where an end effector can be accurately moved to a target position, even if there is an error in the kinematic operation of the robot main body or cameras. A positional deviation integral torque is applied to joints while being superimposed with torques based on angular deviations. This innovative approach ensures that the end effector can reliably reach its target position, thereby reducing calibration loads.
