Abstract
The present disclosure is directed to embodiments including an apparatus, method and system for collapsing/lowering an exo-skeleton device including at least one motor and at least one component. In some embodiments, the device is configured to be moved by the at least one motor. When at least one of a plurality of faults including power faults such as a low power fault and a power failure fault, electrical faults, software faults and mechanical faults are detected in the powering the exoskeleton device, one or more components of the device may be decelerated via the at least one motor.
Claims20
A method for facilitating a controlled collapse of an exoskeleton device including a motor, the method comprising:
- receiving an indication of one or more of a power fault, an electrical fault, a software fault and a mechanical fault of the exoskeleton device which initiates the exoskeleton device or a component thereof to fall to a ground;
- and
- establishing a low impedance circuit between a positive terminal and a negative terminal of the motor so as to cause generation of an electro-magnetic force to resist or slow down the fall of the exoskeleton device or the component.
A collapse circuit for facilitating a controlled collapse of an exoskeleton device including a motor, the circuit comprising:
- a processor configured to receive an indication of one or more of a power fault, an electrical fault, a software fault and a mechanical fault of the exoskeleton device causing the exoskeleton device or a component thereof to initiate a fall to the ground;
- and
- a power driver configured to establishing low impedance between a positive terminal and a negative terminal of the motor so as to cause generation of an electro-magnetic force to resist or slow down the fall of the exoskeleton device or the component.
A method for facilitating a collapse of an exoskeleton device in use by a user, the exoskeleton device including a motor, the method comprising:
- receiving an indication of one or more of a power fault, an electrical fault, a software fault and a mechanical fault of the exoskeleton device causing the exoskeleton device to initiate a fall to a ground;
- determining an amount of electro-magnetic force sufficient to resist or slow down the fall of the exoskeleton device so that a collapse speed of the exoskeleton device during at least a portion of the fall is substantially constant in time;
- and
- establishing a low impedance between a positive terminal and a negative terminal of the motor so as to cause generation of the determined amount of electro-magnetic force to resist or slow down the fall of the exoskeleton device.
