Abstract:
A force/torque transducer comprises a first member, a second member for receiving a load, and load cells connecting the first and second members. The load cells include sensors for measuring physical deformation of the load cells. Sensor measurements are convertible into force/torque measurements using a transformation matrix configured with M rows and N columns. M and N are respectively defined by a number of degrees of freedom monitored by the transducer and a number of load cells employed by the transducer, or vice-versa. Each row or column that corresponds to each load cell has values relating to that one load cell. Each row or column that corresponds to each degree of freedom has values relating to that one degree of freedom. A sum of the values in each row or column corresponding to each degree of freedom is substantially equal to zero.
