PARALLELOGRAM LOAD CELL

摘要

A device includes a first member and a second member disposed in series along a longitudinal axis. The device also includes links coupling first joints of the first member to second joints of the second member. The first and second members and the links arranged to define a planar parallelogram linkage. The devices also include a resilient element disposed between the first member and the second member, the first member and the second member preloaded against the resilient element. The first member and the second member are preloaded to provide an arrangement of the first and the second joints in which a motion of the first joints with respect to the second joints is constrained to a direction substantially parallel to the longitudinal axis. The devices further include a sensor for generating a signal indicating a separation between the first member and the second member.

主权项

1. A device, comprising:
a first member and a second member disposed in series along a longitudinal axis, the first member comprising first joints and the second member comprising second joints; a plurality of links mechanically coupling the first member to the second member via the first and the second joints; and at least one sensor for generating at least one signal indicating a separation between the first member and the second member, wherein the first member, the second member, and the plurality of links are arranged to define at least one substantially planar parallelogram linkage and having a constrained range of motion substantially along the longitudinal axis.
