1. An exoskeleton system comprising:
a left and right leg actuator unit that are respectively coupled to a left and right leg of a user over clothing of the user, the left and right leg actuator units each including:
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 coupled to the upper leg portion above the knee via a first set of couplers that includes a first and second coupler that are joined by a unitary curved rigid plate assembly disposed on and extending around a lateral side of the upper leg portion, with straps of the first and second couplers extending around the upper leg portion, the first coupler disposed and extending completely above a top end of the upper arm, the upper arm coupled to the rigid plate assembly on a lateral side of the upper leg portion and configured to transfer force generated by the upper arm to the upper leg portion,
the lower arm coupled to the lower leg portion below the knee via a second set of couplers that includes a third and fourth coupler, with a coupling branch unit extending from a distal end the lower arm, the coupling branch unit comprising:
a first branch that extends from a lateral position on the lower leg portion, curving upward above the distal end of the lower arm and toward the anterior of the lower leg portion to a first attachment on the anterior of the lower leg portion below the knee, with the first attachment joining the third coupler and the first branch of the coupling branch unit wherein the first branch is spaced apart from the lower leg portion below the knee at rest, and
a second branch that extends from a lateral position on the lower leg portion of the leg, curving downward and toward the posterior of the lower leg portion to a second attachment on the posterior of the lower leg portion below the knee, with the second attachment joining the fourth coupler and the second branch of the coupling branch unit wherein the second branch is spaced apart from the lower leg portion below the knee at rest;
a bellows actuator that extends between the upper arm and lower arm; and
one or more sets of pneumatic lines coupled to the bellows actuator to introduce pneumatic fluid to and remove fluid from the bellows actuator to cause the bellows actuator to expand and contract and move the upper arm and lower arm.
