Abstract
A test platform system for testing lower limb assistive devices includes a lower limb device, a guide system by which the movement of a lower limb device is simulated during its transition between positions, a second motor that performs the movement of the lower limb device, and a moving belt.
Claims20
A test platform system for testing lower limb assistive devices, comprising
- a lower limb device,
- a vertical guide system, wherein a movement of the lower limb device is simulated by the vertical guide system during a transition of the lower limb device between positions,
- a second motor, wherein the second motor performs the movement of the lower limb device, and
- a moving belt,
- wherein the vertical guide system comprises:
- a vertical rail element,
- a center of mass plate positioned on the vertical rail element and movable upwards and downwards on the vertical rail element,
- a vertical ball screw connected to the vertical rail element by means of at least one connection plate,
- a first motor, wherein the first motor is positioned on the vertical ball screw and performs a movement of the center of mass plate (CoM),
- at least one nut, wherein the at least one nut acts on the vertical ball screw and converts a rotational movement of the first motor into a linear movement, wherein the center of mass plate is coupled with the nut via at least one ball bearing, at least one rod, and a nut plate, wherein the nut plate connects the nut to the at least one rod element.

A method of an operation of a test platform system, comprising the steps of:
- a) connecting a lower limb device to the test platform system,
- b) moving a center of mass (CoM) upwards and downwards during a movement of a guide system along the lower limb device,
- c) controlling a position of the CoM of a first motor positioned on a vertical ball screw and performing a CoM motion, and at least one nut acting on the vertical ball screw and converting a rotational movement of the first motor into a linear movement,
- d) controlling sitting-standing and walking movements of the lower limb device on a moving belt and adjusting a speed.
