A mechanical "soldier" busting myths. |
Case in point, the very popular science entertainment show "MythBusters" (produced for the Discovery Channel).
In an episode challenging the concept of destructive harmonics caused by an army marching in unison, MythBusters decided to create an "army" of mechanical feet to march in over a mock bridge. An important requirement was a mechanical rotational movement device that would allow for synchronized movement (simulating the legs of soldiers). Accurate and smooth control of multiple actuators so the cadence could be controlled was crucial. Enter Kinetrol.
To see a 4 minute clip of the setup, test and results, see Kinetrol in action on the Breakstep Bridge Minimyth here.
Below are some images from the broadcast.
