Abstract: Systems and methods related to multiple degree of freedom force sensors are disclosed. One aspect of the disclosure provides a load sensor. The load sensor comprises a first plate and a second plate, a plurality of single-axis load cells including first, second, and third single-axis load cells, wherein each of the first, second, and third single-axis load cells is disposed between the first plate and the second plate and is oriented along a first axis, and a plurality of constraint joints coupled to the first plate and the second plate, the plurality of constraint joints configured to inhibit translation of the first plate relative to the second plate in directions perpendicular to the first axis and configured to inhibit rotation of the first plate relative to the second plate about the first axis.
