Lower limb exoskeleton

A method to augment motion of a user, comprising:

• disposing a foot plate within a boot of the user;
• connecting a first adapter to a side surface of the foot plate, the first adapter including a slot exposed towards an external portion of the boot;
• providing a shin pad configured to couple with a shin of the user;
• coupling at least one housing of one or more housings with the shin pad;
• enclosing electronic circuitry and an electric motor within the one or more housings, wherein the electronic circuitry and the electric motor are configured to generate torque about an axis of rotation of an ankle joint of the user;
• forming a second adapter from an end surface of a post;
• and
• connecting a chassis to the post to form an actuator module;
• wherein the slot of the first adapter is configured to:
• receive the second adapter of the actuator module upon insertion of the second adapter into the slot, wherein the second adapter and the post are at a first angle relative to the first adapter;
• and
• lock the second adapter upon rotation of the second adapter and the post from the first angle to a second angle relative to the first adapter to configure the actuator module to generate torque about the axis of rotation of the ankle joint of the user.
