A force measurement system includes an effector device with a hollow
interior, an inner support secured within the hollow interior of the
effector device, and at least one sensor secured at a selected location
to the inner support and configured to measure a force applied to the
inner support. At least one outer surface portion of the inner support is
coupled with at least one interior surface portion of the effector device
such that forces applied to the effector device are at least partially
transferred to the inner support for measurement by the sensor.
