  • Patent number: 11337881
    Abstract: A control system and method for an exoskeleton is provided. The control system utilizes the admittance control paradigm to provide a system and method for manipulating the exoskeleton using minimal force from the user. A force/torque sensor and servo motors are fitted onto a passive arm support, enabling motorized support for a user with upper extremity weaknesses. The exoskeleton may be used on any extremity. The admittance control paradigm includes an impedance control and an admittance control to allow a user with upper extremity weakness and limited independence to intuitively and with minimal force control the precise trajectory of their arms to achieve a greater degree of independence in activities of daily living. Unlike existing passive arm supports that utilize springs or rubber bands to balance the user's arm against gravity, this system provides more precise gravity compensation and minimizes the amount of force required to control the exoskeleton.

    Abstract: A robot design system, and associated method, that is particularly well-suited for legged robots (e.g., monopods, bipeds, and quadrupeds). The system implements three stages or modules: (a) a motion optimization module; (b) a morphology optimization module; and (c) a link length optimization module. The motion optimization module outputs motion trajectories of the robot's center of mass (COM) and force effectors. The morphology optimization module uses as input the optimized motion trajectories and a library of modular robot components and outputs an optimized robot morphology, e.g., a parameterized mechanical design in which the number of links in each of the legs and other parameters are optimized. The link length optimization module takes this as input and outputs optimal link lengths for a particular task such that the design of a robot is more efficient. The system solves the problem of automatically designing legged robots for given locomotion tasks by numerical optimization.

  • Patent number: 10195099
    Abstract: Motion of a body segment is assisted when the body segment is moving in a positive power mode but not when it is moving in a negative power mode. When the motion of the body segment is cyclical, for example during walking, assistance to the body segment is switched on and off throughout the cycle to correspond to positive and negative power modes respectively. Energy used to assist the body segment may be harvested from prior motion of the body segment, either in prior cycles and/or when the body segment is moving in a negative power mode. The energy used may also be harvested from other body segments. Assisting motion of a body segment may be used to reduce the metabolic cost of locomotion, or to reduce exertion, when walking, jogging, running or sprinting.

  • Patent number: 10179078
    Abstract: The invention relates to embodiments of methods for extending a subject-controllable range of joint motion, and for increasing subject control of joint movement within a range of motion. Embodiments include fastening a powered device around a joint so as to be able to control the joint, allowing the subject to move the joint within a range of volitional motion, and then engaging the powered device to support movement of the joint into an expanded, rehabilitative range. In some embodiments, the device supports joint movement by substantially providing the force to move the joint beyond the volitional boundary. In other embodiments, supporting movement includes the subject substantially providing the force, and the device allowing movement only in a desired direction. The invention further relates to a system for increasing the functional capability of a joint by implementing embodiments of the method.

  • Patent number: 10086890
    Abstract: A robot includes a main body, a handlebar disposed on the main body and grippable by a user, a detection unit that detects a load applied to the handlebar, a moving device including a rotating body and moving the robot by controlling the rotation of the rotating body, and a switching unit that switches a support mode for supporting the user with walking. The support mode includes a first mode in which the robot autonomously moves to guide the user who is walking and a second mode in which the robot moves in accordance with a first load detected by the detection unit. When the robot moves in the first mode, the switching unit switches the support mode from the first mode to the second mode on the basis of the second load detected by the detection unit.

  • Patent number: 10016330
    Abstract: Provided is a step assist device including a first phase angle modifying section that, according to repetition of the step movement, modifies in a staged manner the phase angle input thereto, based on a predetermined phase change pattern, such that a phase pattern of the phase angle approaches a straight line relative to the passage of time, and outputs the modified phase angle as a first modified phase angle. The control section acquires a target value based on a continuous change pattern of the auxiliary force set in advance for at least one of the first modified phase angle and a prescribed phase angle, and controls the providing section according to the target value.

  • Patent number: 9789919
    Abstract: An example implementation involves receiving measurements from an inertial sensor coupled to the robot and detecting an occurrence of a foot of the legged robot making contact with a surface. The implementation also involves reducing a gain value of an amplifier from a nominal value to a reduced value upon detecting the occurrence. The amplifier receives the measurements from the inertial sensor and provides a modulated output based on the gain value. The implementation further involves increasing the gain value from the reduced value to the nominal value over a predetermined duration of time after detecting the occurrence. The gain value is increased according to a profile indicative of a manner in which to increase the gain value of the predetermined duration of time. The implementation also involves controlling at least one actuator of the legged robot based on the modulated output during the predetermined duration of time.

  • Patent number: 9744093
    Abstract: A leg support exoskeleton is strapped on as wearable device to support its user during squatting. The exoskeleton includes a knee joint connected to a first line and a second link, which is configured to allow flexion and extension motion between the first link and the second link. A force generator has a first end that is rotatably connected to the first link. A constraining mechanism is connected to the second link and has at least two operational positions. In a first operational position, the second end of the force generator engages the constraining mechanism, where the first link and the second link flex relative to each other. In a second operational position, the second end of the force generator does not engage the constraining mechanism; the first link and the second link are free to flex and extend relative to each other.

  • Patent number: 9707147
    Abstract: The present invention provides a device which can generate commands for controlling a physical therapy apparatus adapted to accept external commands. The device has a base, a motion manipulation portion and a moveable portion of substantially the same shape and dimensions as the portion of the physical therapy apparatus which interacts with at least one part of the body of a patient. The device also includes conversion means for converting stored time-dependent output signals to a series of command signals and means for transmitting the command signals to the physical therapy apparatus. The command signals are produced by the movements of the moveable portion, and, when transmitted to the physical therapy apparatus, can induce the physical therapy apparatus to undergo a series of motions substantially identical to those of the moveable portion.
