  • Patent number: 10816417
    Abstract: A force detector includes a support, fluid bags, a contact portion, a detector, and a computer. The contact portion is opposite to a side on which the fluid bags are in contact with the support and is adjacent to the fluid bags. 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 between the object and the contact portion based on a difference between the internal pressures of the fluid bags.
