An apparatus, method, and system for controlling motion in six degrees of freedom is described. The apparatus includes a support structure, a first pedal and a second pedal. A first set of three independent articulating mechanisms is operatively connected to the support structure and the first pedal. The first set of three independent articulating mechanisms, in combination, enable motion of the first pedal in three control axes corresponding to three discrete degrees of freedom. A second set of three independent articulating mechanisms, operatively connected to the second pedal, enable motion, in combination, in three control axes corresponding to a discrete second set of three degrees of freedom. The apparatus may also include first and second sensors configured to detect the motion of the first and second pedals.

The apparatus of claim 1, wherein at least one of the independent articulating mechanisms of the first set is configured to enable discrete motion of the first pedal in an axis corresponding to forward and backward in-plane translation. 3. The apparatus of claim 1, wherein at least one of the independent articulating mechanisms of the first set is configured to enable discrete motion of the first pedal in an axis corresponding to lateral in-plane translation to the left and right of a human operator. 4. The apparatus of claim 1, wherein at least one of the independent articulating mechanisms of the first set is configured to enable discrete motion in an axis corresponding to moving the first pedal up and down vertically. 5. The apparatus of claim 1, wherein at least one of the independent articulating mechanisms of the second set is configured to enable discrete rotation of the second pedal about an axis collinear with the rotational axis for flexion and extension of an ankle of a human operator. 6. The apparatus of claim 1, wherein at least one of the independent articulating mechanisms of the second set is configured to enable discrete rotation of the second pedal about a horizontal axis corresponding to lateral rolling of an ankle of a human operator. 7. The apparatus of claim 1, wherein at least one of the independent articulating mechanisms of the first set includes a centering mechanism for specifying a neutral position of the first pedal. 8. The apparatus of claim 7, wherein at least one of the independent articulating mechanisms of the second set includes a centering mechanism for specifying a neutral position of the second pedal. 9. The apparatus of claim 8, wherein the centering mechanism for specifying a neutral position is spring-driven, and a deflection force necessary for moving the first pedal and the second pedal is determined by the spring-driven centering mechanism. 10. The apparatus of claim 1, wherein one of the independent articulating mechanisms of the first set is configured to enable motion in a rotational control axis that corresponds with a rotational axis of a joint of a leg of a human operator. 11. The apparatus of claim 1, further comprising: a first sensor configured to detect the motion of the first pedal in at least one of three degrees of freedom; anda second sensor configured to detect the motion of the second pedal in at least one of three degrees of freedom. 12.
