This video introduces a compliant three-degree-of-freedom (3 DOF) spherical mechanism that uses the collective deformations of blue flexures to ensure that every point trajectory on both its white dome-shaped frame and attached yellow probe lie in concentric spherical shells around a single stationary point (i.e., the center of the probe’s sphere). The mechanism was designed as a vibrating compliant kinematic sculpture to mesmerize students that poke at it.
The flexures used were adapted from a design proposed by Professor Just Herder’s group from Delft University of Technology. A link to their paper published in Precision Engineering is provided here:
