Design and Analysis of a Rigid-Flexible Parallel Mechanism for a Neck Brace

Figure 16

The rotation angles α, β, and γ of the moving platform changing with time t during flexion and extension, lateral bend, and torsion. (a) The rotation angle α changes with time t during flexion and extension. (b) The rotation angle β changes with time t during lateral bend. (c) The rotation angle γ changes with time t during torsion.
