Thus, the passive walker reported here can stand still.
The number of new walkers joining each month remained stable for the first 8 months of the scheme.
The yaw motion should be eliminated since it destabilizes the walker.
The decoherence operators in equation (85) project the walker onto one of the vertices of the hypercube chosen uniformly at random.
This walker has two equal legs, modeled as rigid bodies coupled with a frictionless hinge at the hip.
The simulation shows that the compensator, indeed, effectively compensates for both the yaw and the roll motion, and that the walker is stable.
Specifically, wheeled walkers are associated with higher speed and cadence, lower energy demands, more normal-appearing gait, and higher patient s atisfaction.
It seems that the mechanical parameters of these walkers work better than the complicated control system of the conventional robots in generating natural looking gaits.
