    Force sensing is advantageous in walking and can signal leg slipping that could destabilize support of body weight, prior to changes in body position. Recordings of strain-detecting campaniform sensilla in blow fly legs showed force encoding in ranges reflecting their minimal body weight but firing was also inhibited by very small transient force decreases. A mathematical model of the receptors reproduced these characteristics and could aid in control of walking machines, independent of size and mass.

    Discharges of sensory receptors (campaniform sensilla) in the hind legs of stick insects can differentially signal forces that occur in walking uphill versus walking downhill. Unexpectedly, sensory firing most closely reflects the rate of change of force (dF/d t) even when the force levels are high. These signals have been replicated in a mathematical model of the receptors and could be used to stabilize leg movements both in the animal and in a walking robot.
