Abstract
A system for estimating friction, the system including a contact surface including a plurality of protrusions extending from a base surface, the contact surface further including a first contact surface region and a second contact surface region, the first contact surface region being configured to resist slip less than the second contact surface region, and a sensor arrangement configured for detecting displacement of at least three of the plurality of protrusions in three different dimensions to measure a three-dimensional force applied to the at least three plurality of protrusions at a moment of slippage of the first contact surface region.

A system for estimating friction, the system comprising:
- a contact surface comprising a plurality of protrusions extending from a base surface, the contact surface further including a first contact surface region and a second contact surface region, the first contact surface region being configured to resist slip less than the second contact surface region;
- and
- a sensor arrangement configured for detecting displacement of at least three of the plurality of protrusions in three different dimensions to measure a three-dimensional force applied to the at least three of the plurality of protrusions at a moment of slippage of the first contact surface region.
