Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for an exosuit activity transition control structure. In some implementations, sensor data for a powered exosuit is received. The sensor data is classified depending on whether the sensor data is indicative of a transition between different types of activities of a wearer of the powered exosuit. The classification is provided to a control system for the powered exosuit. The powered exosuit is controlled based on the classification.

A load reduction assistance device is provided with an acquisition unit configured to acquire position information of a user wearing a load reduction device that reduces a load on the user; a status detection unit configured to extract an operation mode of the load reduction device corresponding to a surrounding environment state based on the position information of the user; and an operation control unit configured to cause the load reduction device to operate in the extracted operation mode.

An assist device includes a first body-worn unit; second body-worn units; an actuator; a controller configured to obtain an assist parameter that determines assist torque to be generated, and perform control to operate the actuator at an output based on the assist parameter; and a tilt angle detection part configured to obtain tilt angle information on a tilt angle of an upper body of a user. The actuator includes arms; and swing angle detection parts configured to obtain swing angle information on swing angles of the arms that represent angles formed by the upper body and thighs of the user. The controller is configured to obtain the assist parameter based on the swing angle information and the tilt angle information.

An assist device includes a first body-worn unit, second body-worn units, an actuator, a sensor, and a controller including a processing unit configured to obtain a command value for assist torque based on a detection result of the sensor and using correspondence information indicating a relation between a forward swing speed of a leg and a torque compensation value including first and second torque compensation values. The processing unit is configured to perform an adjustment process of changing the first torque compensation value based on the forward swing angle of at least one of right and left legs of a user, in a case where the processing unit obtains the command value.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating, using, or both, exosuit historical data. In some implementations, (i) sensor data generated by sensors of an exosuit worn by a user and (ii) control data indicating actions performed by or control signals generated by the exosuit based on the sensor data while worn by the user are received. The sensor data and the control data are added to a database that includes historical data describing use of the exosuit over time by the user. A control scheme of the exosuit is customized for the user by updating the one or more machine learning models or settings that govern the application of the one or more machine learning models. Forces provided by one or more actuators of the exosuit are controlled using the updated one or more machine learning models or the updated settings.

A method for moving an exoskeleton from a seated position to a standing position (and vice versa) in which none of the degrees of freedom of the exoskeleton is non-actuated. The method includes the implementation by a data processor of steps of: (a) generating a trajectory of the exoskeleton from the seated position to the standing position (and vice versa), the trajectory being parameterised as a function of time; (b) applying to the trajectory a set of virtual constraints on the actuated degrees of freedom, the virtual constraints being parameterised by a phase variable; and (c) running a controller of the exoskeleton associated with the set of virtual constraints such that the exoskeleton moves from the seated position to the standing position (and vice versa), the controller being capable of generating commands for the actuators so as to comply with the virtual constraints during the trajectory.

An exoskeleton comprising a plurality of support structures, and a plurality of joint mechanisms each joint mechanism rotatably coupling at least two of the plurality of support structures. A sensor discrepancy detection system can be operable to compare sensor output data from a user operated force moment sensor and at least one torque sensor of a joint mechanism. A controller can be configured to recruit at least one substitute sensor from a first sensor group of based on an identified discrepancy between the sensor output data and to execute a remedial measure associated with a safety mode of the exoskeleton for safe operation of the exoskeleton.

The present invention is in the sector of wearable robotic devices, and in particular it concerns a method for the adaptive control of a wearable robot.

Exosuit systems and methods according to various embodiments are described herein. The exosuit system can be a suit that is worn by a wearer on the outside of his or her body. It may be worn under the wearer's normal clothing, over their clothing, between layers of clothing, or may be the wearer's primary clothing itself. The exosuit may be assistive, as it physically assists the wearer in performing particular activities, or can provide other functionality such as communication to the wearer through physical expressions to the body, engagement of the environment, or capturing of information from the wearer.

A wearable device for assisting a human body movement according to an embodiment of the present disclosure includes a sensor including an inner electrode arranged at a center of an arbitrary circle, a plurality of outer electrodes arranged at regular intervals in a circumferential direction at positions spaced apart from the inner electrode in a radial direction so as to be arranged on a circumference of the circle, and a plurality of deformation elements disposed between the inner electrode and each of the outer electrodes and formed of a material whose resistance is changed by deformation; a controller configured to apply different control signals to an actuator according to a combination of different resistance values of the deformation elements of the sensor; and the actuator operating based on the control signals of the controller.
