Driving a five-finger robotic hand from glove-mounted strain gauges.

The brief

A wearable glove carries one strain gauge across each finger, wired into a Wheatstone bridge. The clinical team asks for a benchtop demonstrator: five bridge channels in the millivolt range, conditioned to produce a per-finger drive that closes a corresponding finger on a desktop robotic hand. Live finger-curl data is captured from a webcam using ML5 hand-pose tracking and treated as the simulated transducer input for each of the five sensors.

Which of the blocks you have studied so far would you place between the strain gauge and the servo, and in what order?
