Classification: CPC A  B | IPC A

Claim 0:
1. A robotic system configured to execute a semi-supervised intent recognition control program, the robotic system comprising a leg actuator unit that includes:
a processor;
a user interface comprising a single button;
a joint configured to be aligned with a knee of a leg of a user wearing the leg actuator unit;
an upper arm coupled to the joint and extending along a length of an upper leg portion above the knee of the user wearing the leg actuator unit;
a lower arm coupled to the joint and extending along a length of a lower leg portion below the knee of the user wearing the leg actuator unit; and
an actuator configured to actuate the upper arm and lower arm and move the leg actuator unit into a plurality of different position states, and
where executing the semi-supervised intent recognition control program causes the robotic system to:
receive a state transition intention input via the single button for indicating, via only pressing the single button, an intention to make a state transition without indicating, via pressing the single button, a specific state transition of a plurality of possible state transitions to be made, and pressing the single button only indicating a user intention to make a state transition from a first state to a second state, with the second state being identifiable by the robotic system from a plurality of possible different states, only the single button is useable to generate the state transition intention input, and
in response to the state transition intention input, the processor is configured to change the robotic system from operating in a first mode with sensitivity to detecting state transitions at a first sensitivity level to temporarily operating in a second mode with sensitivity to detecting state transitions while operating in the second mode at a second sensitivity level that is more sensitive than the first sensitivity level;
identify a state transition of the plurality of possible state transitions to be made while operating in the second mode and using the second sensitivity level, and in response, facilitate the identified state transition by actuating the robotic system; and
automatically switch back to the first mode from the second mode without input from the single button.
