  • Cable force adjustment
    Patent number: 11941160
    Abstract: A method includes transmitting an instruction to a motive power supply of an elastically deformable device to drive the elastically deformable device in accordance with a drive setting; measuring a force exerted on the elastically deformable device with a sensor; outputting an observed value representative of the force; comparing the observed value with a reference value corresponding with a predetermined force to be exerted on the elastically deformable device; and adjusting the drive setting based on a determination that the observed value is outside of a predetermined range of the reference value. The method prevents slack in the elastically deformable device over time. Related apparatuses, systems, techniques and articles are also described.
