Motion base for displacing an object above a support surface

A motion base for displacing an object above a support surface, the motion base comprising:

• a base assembly having a motor coupled thereto;
• a support structure configured to be coupled to the object, the support structure comprising a displaceable carriage configured to be coupled to the object, the displaceable carriage having a support surface configured to support both a first foot and a second foot of a person within the displaceable carriage and being rotatably coupled to the base assembly about a transverse rotational axis, the transverse rotational axis being disposed beneath a top surface of the object;
• an actuation system, the actuation system including one or more actuators operatively coupled to the support structure, at least one of the one or more actuators including a rotation member rotated by the motor at a bottom end thereof,
• wherein a top end of the at least one of the one or more actuators is mounted to the displaceable carriage such that the support surface of the displaceable carriage is suspended below the top end of the at least one of the one or more actuators of the actuation systems, and the one or more actuators configured to rotate the support structure relative to the base assembly about the transverse rotational axis and translate the support structure so as to simulate a rotation of the support structure about an imaginary rotational axis disposed above the top surface of the object;
• and
• one or more data processing devices operatively coupled to the actuation system, the one or more data processing devices configured to generate control signals that rotate the support structure relative to the base assembly about the transverse rotational axis and translate the support structure, thereby simulating the rotation of the support structure about the imaginary rotational axis disposed above the top surface of the object.

A motion base for displacing a force measurement assembly, the motion base comprising:

• a base assembly having a motor coupled thereto;
• a support structure configured to be coupled to the force measurement assembly, the support structure comprising a displaceable carriage configured to be coupled to the force measurement assembly, the displaceable carriage having a support surface configured to support both a first foot and a second foot of a person within the displaceable carriage and being rotatably coupled to the base assembly about a transverse rotational axis, the transverse rotational axis being disposed beneath a top surface of the force measurement assembly;
• an actuation system, the actuation system including one or more actuators operatively coupled to the support structure, at least one of the one or more actuators including a rotation member rotated by the motor at a bottom end thereof,
• wherein a top end of the at least one of the one or more actuators is mounted to the displaceable carriage such that the support surface of the displaceable carriage is suspended below the top end of the at least one of the one or more actuators of the actuation systems, and the one or more actuators configured to rotate the support structure relative to the base assembly about the transverse rotational axis and translate the support structure so as to simulate a rotation of the support structure about an imaginary rotational axis disposed above the top surface of the force measurement assembly;
• and
• one or more data processing devices operatively coupled to the actuation system of the motion base and the force measurement assembly, the one or more data processing devices configured to generate control signals that rotate the support structure relative to the base assembly about the transverse rotational axis and translate the support structure, thereby simulating the rotation of the support structure about the imaginary rotational axis disposed above the top surface of the force measurement assembly.
