Problems solved by technology
[0005] However, this type of force sensor has the following problems: the collision between the intermediate platform and the limit protrusion is introduced, which affects the measurement accuracy, so it is only suitable for static measurement; the force resolution is only two levels, which has great limitations, although Multi-level force resolution can be achieved by means of multi-level limit, but this method easily leads to complex structure of the sensor, and the obtained force resolution is discrete; the two-level force resolution of the force sensor is coupled together, that is, in The force resolution is higher under a small force, but the resolution is lower under a larger force, and the uniqueness of the resolution in the entire measurement range cannot be achieved

Description
technical field [0001] The invention relates to the technical field of force sensors, in particular to a variable configuration force sensor with continuously adjustable force resolution. Background technique [0002] In the field of robotics, the force sensor is mainly used to measure the force on the robot, and provides force information for the force control of the robot, so that it can complete some complex and precise operation tasks, and plays an important role in realizing the intelligentization of the robot. . [0003] In robot operations, different manipulation tasks have different requirements for force control accuracy. For the common force sensor with a single force resolution, the control precision that the robot can achieve is limited. It is neither economical nor practical to equip a robot with a high-resolution force sensor to cope with the multi-task force control accuracy requirements. If multiple force sensors with different force resolutions are used, ...
