Claim 15:
16. A hand controller, comprising:
a control member movable in at least one degree of freedom between a neutral position and a plurality of deflection positions including at least a first deflection position and a second deflection position;
a plurality of scissor spring assemblies coupled to the control member, wherein the scissor assemblies include at least a first scissor spring assembly, a second scissor spring assembly, and a third scissor spring assembly, wherein the first scissor spring assembly is configured to actuate in response to the control member moving in a first dimension, wherein the second scissor spring assembly is configured to actuate in response to the control member moving in a second dimension, wherein the third scissor spring assembly is configured to actuate in response to the control member moving in a third dimension, wherein the first, second, and third dimensions are perpendicular to one another, and wherein each of the first, second, and third scissor spring assemblies comprises:
a scissor apparatus comprising a first scissor jaw and a second scissor jaw that are coupled together, wherein the first scissor jaw has a first jaw face, wherein the second scissor jaw has a second jaw face that opposes the first jaw face, wherein the scissor apparatus is configured to actuate between a closed position and a plurality of open positions including at least a first open position and a second open position, and wherein a distance between the first and second jaw faces increases as the scissor apparatus actuates from the closed position to the open positions;
a pivot pin extending through the first and second scissor jaws, wherein the first and second jaws are configured to rotate around the pivot pin as the scissor apparatus actuates between the closed position and the open positions;
a dynamic pin positioned between the first jaw face and the second jaw face, wherein the dynamic pin is configured to push against the first jaw face in a first direction such that the dynamic pin and the first scissor jaw move in the first direction to actuate the scissor apparatus into the first open position in response to the control member moving into the first deflection position, wherein the dynamic pin is configured to push against the second jaw face in a second direction such that the dynamic pin and the second scissor jaw move in the second direction to actuate the scissor apparatus into the second open position in response to the control member moving into the second deflection position, and wherein the first and second directions are arcuate and opposite of one another;
a static pin positioned at least partially between the first jaw face and the second jaw face, wherein the static pin prevents the second scissor jaw from moving as the scissor apparatus actuates into the first open position, and wherein the static pin prevents the first scissor jaw from moving as the scissor apparatus actuates into the second open position; and
a biasing member extending around an outer perimeter of the scissor apparatus, wherein the biasing member is configured to provide a bias force that actuates the scissor apparatus into the closed position and moves the control member into the neutral position in response to a user releasing the control member.
