A sensing fretboard for stringed instruments is described herein with respect to a guitar. The present invention includes custom frets and a modular sensing array that can be incorporated into a fretboard and coupled to the guitar. By measuring the dynamic forces applied by the players on the frets and strings of the guitar, musicians can be warned in real time during practice, when their grip is too strong, and to help musicians learn and recover from injuries.

A baseline unit for use in a sensor system, the sensor system comprising N force sensors which output N sensor signals, respectively, where N≥2, the baseline unit configured to: monitor measures of gradients of the respective sensor signals; and, in dependence upon the measures of the gradients, control a stored baseline setting to control how a baseline signal for at least one of said sensor signals is calculated using a baseline-calculation method, the baseline-calculation method configured by the currently-stored baseline setting.

Systems and methods to test robotic end effectors may comprise a testing rig having variable mass properties. The testing rig may include a variable weight assembly and a movement assembly that can adjust a position or orientation of the variable weight assembly. In this manner, the testing rig can be modified to simulate or replicate mass properties of a plurality of items, and grasp performance of a robotic end effector may be measured using the testing rig. Further, simulation models of end effectors and items may be validated based on actual grasp performance of a robotic end effector and the testing rig having variable mass properties.

Various tactile sensors and associated methods are enabled. For instance, a sensing apparatus comprises a photosensitive sensor. A compound-eye structure is on the photosensitive sensor and an elastomer layer is on the compound-eye structure. A reflective layer is on the elastomer layer, opposite the compound-eye structure and a light source emits light between the reflective layer and the compound-eye structure.

A force sensing device for use in a robotic finger including: a first segment, the first segment having a first joint at a first end thereof; a second segment, the second segment being connected to the first segment by a second joint; and a third segment, the third segment being connected to the second segment by a third joint; and torque sensor for sensing the torque at each of the joints when a force is applied to the third segment. The first, second and third joints are disposed within the same plane and are disposed in a triangular arrangement.
