1. A system for assessing grip security, the system comprising:
a contact surface having at least 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,
a sensor for detecting slip in the first contact surface region, wherein the contact surface comprises a plurality of protrusions extending from a base surface, the protrusions in the first contact surface region extending away from the base surface a distance less than the protrusions in the second contact surface region.
