Extended Data Fig. 2: Pitch and height configuration for the exoskeleton.

(a) Schematic of the methodology used to configure the pitch and height settings of the exoskeleton. (b) Images of a freely behaving mouse overlaid with digitally labelled points on the left paws and other body parts, moving at 3 different forwards velocities (1., low velocity; 2., medium velocity; 3., high velocity). (c) Left - Plot of head pitch angles and velocity for all mice (n = 4), with a quadratic fit to the data (red) and the pitch value implemented on the exoskeleton (blue). Numbers correspond to images in (b). Middle - Plot of snout height and velocity for all mice (n = 4), with a quadratic fit to the data (red) and the height value implemented on the exoskeleton (blue). Numbers correspond to images in (b). Right - Plot of the pitch angle and snout height for all mice (n = 4), with a quadratic fit to the data (red) and the height value implemented on the exoskeleton (blue).
