1. A system for manufacturing a mobility aid device having a kinetic shape, the system comprising:
a user interface, including a user input device;
a processor;
a memory communicatively connected to the processor and having a set of software instructions stored thereon which, when executed by the processor, cause the processor to:
receive information regarding: vertical applied force during a stance phase of a given subject's gait based on the given subject's weight, and a personalized measurement of the given subject's gait, and desired horizontal force to be applied by the mobility aid device during the given subject's stance phase;
determine a desired reaction force profile based on the personalized measurement, the vertical applied force, and the desired horizontal force, the desired reaction force profile corresponding to desired forces to be applied to the given subject during the given subject's stance phase;
determine a two-dimensional profile for a roll over shape of the mobility aid device based on the information regarding the vertical applied force and the desired reaction force profile to provide the desired reaction force profile upon application of the vertical applied force at an axis of the roll over shape of the mobility aid device of the given subject, according to:

OG Complex Work Unit Math
where θ is an angular position around the two-dimensional profile, R is a radius of the two-dimensional profile, Fv is the vertical applied force, Fr is the desired reaction force profile, and θi is an initial angle of the object; and
design the mobility aid device personalized for the given subject, the mobility device comprising the roll over shape based on the two-dimensional profile; and
output a file representing the mobility aid device including the roll over shape based on the two-dimensional profile in memory.
