Abstract: A lower-leg exoskeleton that includes an actuator configured to be worn about a portion a leg of a user that is below the knee of the user; and a foot structure coupled to a first actuator end of the actuator, the foot structure configured to surround a portion of the foot of the user. The foot structure includes one or more sidewalls configured to extend around the foot of the user and including one or more sidewall attachment points for connecting to a base portion, and a base portion configured to reside at a base of the foot of the user and including one or more base attachment points coupling with the one or more sidewall attachment points.

Abstract: A lower-leg exoskeleton that includes an inflatable actuator configured to be worn over a front portion of a leg of a user and configured to be disposed directly adjacent to and surrounding a joint of the leg of the user. The inflatable actuator is configured, when worn by the user, to receive and transmit an actuator load generated by the inflatable actuator around the joint of the user to a load contact point. Inflation of the inflatable actuator generates a moment about the joint of the user to cause flexion of the leg of the user.

Abstract: A lower-leg exoskeleton including an inflatable actuator that is configured to be worn over a front portion of a foot of a user; a rigid foot structure coupled to the inflatable actuator that is configured to surround a portion of a foot of the user; and a rigid shin structure coupled to the inflatable actuator and configured to engage the shin of the user. When worn by a user, the lower-leg exoskeleton can receive and transmit an actuator load generated by the inflatable actuator to a load contact point defined by the rigid foot structure which is forward of the heel of a user. Inflation of the inflatable actuator can generate a moment about the ankle of a user to cause flexion of the foot of the user.
