1. An end effector for use with a moving device, said end effector comprising:

  • a) a frame;

    b) a plurality of operational members configured for longitudinal movement on said frame;

    c) an actuation mechanism connected to a first operational member of said plurality of operational members and configured and operable to move said first operational member from a first position to a second position;

    d) a linking apparatus for linking said first operational member to a second operational member of said plurality of operational members said second operational member not directly connected to said actuation mechanism;

    said actuation mechanism being configured and operable to move said first operational member from said first position to said second position, such that said second operational member is operable to be moved by said linking apparatus from a third position to a fourth position;

    and wherein said actuation mechanism comprises;

    i) at least one cam block having a cam slot in an upper surface of said at least one cam block said cam slot extending in a generally transverse direction that is generally orthogonal to the direction of longitudinal movement, said at least one cam block also being configured for longitudinal movement relative to said frame;

    ii) a generally longitudinally oriented member attached to and extending between said at least one cam block and said first operational member;

    iii) a rotary cam configured and operable for rotation about an axis that is generally orthogonal to said direction of longitudinal movement and said transverse direction, said rotary cam being configured for connection to a rotatable drive shaft that is also rotatable generally about said axis;

    said rotary cam having at least one cam follower protruding from said rotary cam, wherein said at least one cam follower is configured and operable for movement transversely inside said cam slot of said at least one cam block and thus is operable to move said at least one cam block in a longitudinal direction during rotation of said rotary cam.
