Abstract
A soft robotic ankle-foot orthosis exosuit includes a brace configured to be worn on a user's foot, a first soft actuator, a second soft actuator, and a pneumatic system. The first soft actuator is coupled to the brace so that it is configured to be positioned proximate a top of the user's foot. The second soft actuator is also coupled to the brace and is configured to be positioned proximate a side of the user's foot. The pneumatic system is configured to change an internal pressure of the first soft actuator and the second soft actuator.
Claims20
A soft robotic ankle-foot orthosis exosuit comprising:
- a brace configured to be worn on a user's foot;
- a first soft actuator coupled to the brace and configured to be positioned proximate a top of the user's foot;
- a second soft actuator coupled to the brace and configured to be positioned proximate a side of the user's foot;
- and
- a pneumatic system configured to change an internal pressure of the first soft actuator and the second soft actuator.
A soft robotic ankle-foot orthosis exosuit comprising:
- a brace configured to be worn on a user's foot;
- sensors coupled to the brace;
- a first soft actuator coupled to the brace and configured to provide dorsiflexion assistance to the user's foot;
- a second soft actuator coupled to the brace and configured to limit inversion or eversion of the user's foot;
- and
- a pump in fluid communication with the first soft actuator and the second soft actuator, the pump configured to adjust an internal pressure of the first soft actuator and an internal pressure of the second soft actuator based on measurements from the sensors.
A soft robotic ankle-foot orthosis exosuit comprising:
- a brace configured to be worn on a user's foot;
- an actuator array coupled to the brace proximate a top of the user's foot, the actuator array including multiple interconnected fluid bladders;
- a first side actuator coupled to a first side of the brace;
- a second side actuator coupled to a second side of the brace;
- and
- a pneumatic system supported by the user away from the brace, the pneumatic system configured to substantially uniformly change an internal pressure in the interconnected fluid bladders and substantially uniformly change an internal pressure in the first and second side actuators.
