An exoskeleton system comprising a leg actuator unit that is configured to be coupled to a leg of a user. The leg actuator unit includes: an upper arm and a lower arm that are rotatably coupled via a rotatable joint, the rotatable joint configured to be positioned at a knee of the user with the upper arm coupled about an upper-leg portion of the user above the knee and with the lower arm coupled about a lower-leg portion of the user below the knee. The upper arm is configured to be coupled to the upper-leg portion above the knee via a first set of couplers that includes a first upper-leg coupler, the lower arm is configured to be coupled to the lower-leg portion below the knee via a second set of couplers that includes one or more lower-leg couplers associated with a lower-leg brace, and an actuator extends between the upper arm and lower arm, the actuator configurable to move the upper arm and lower arm.

Fit and suspension systems and methods for a mobile robot

A method of performing a fit test on an actuator unit coupled to a user. The method includes actuating the actuator unit; determining a first configuration of the actuator unit generated during the actuating the actuator unit; determining a second configuration of the actuator unit generated during the actuating the actuator unit; determining a change in configuration of the actuator unit based at least in part on the difference between the first and second configuration; and determining that the change in configuration corresponds to an improper fit of the actuator unit to the user.

Exoskeleton fit evaluation system and method

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.

Lower-leg exoskeleton system and method

A fluidic exoskeleton system. The system can include one or more fluidic actuator units that have: a joint; a first and second arm coupled to the joint; an inflatable bellows actuator extending between a first and second plate associated with the joint, the inflatable bellows actuator defining a bellows cavity, the inflatable bellows actuator configured to extend along a length of the bellows actuator when inflated by introducing fluid into the bellows cavity; and one or more constraint ribs extending from the joint and surrounding portions of the bellows actuator along the length of the bellows actuator.

Leg exoskeleton system and method

A method of performing a fit test on an actuator unit coupled to a user. The method includes determining a first configuration of the actuator unit generated in response to actuating the actuator unit while the user is performing one or more movements for the fit test; determining a change from the first configuration of the actuator unit while the user is performing the one or more movements for the fit test; determining that the change from the first configuration corresponds to an improper fit of the actuator unit coupled the user; and generating an improper fit indication that indicates improper fit of at least leg actuator units coupled the user.

Exoskeleton continuous-use fit evaluation system and method

A method of performing a fit test on an actuator unit coupled to a user. The method includes determining a first configuration of the actuator unit while the actuator unit is in an un-actuating state and while the user is in a fit test position; actuating the actuator unit; determining a second configuration of the actuator unit generated in response to the actuating the leg actuator unit; determining a change in configuration of the actuator unit based at least in part on the difference between the first and second configuration; and determining that the change in configuration corresponds to an improper fit of the actuator unit to the user.

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.
