Abstract: A twisted string transmission system comprises a twisted string actuator, a force sensor, and a controller. The twisted string actuator is for converting a rotational motion into a linear force. The force sensor is for sensing the linear force. The controller is for receiving sensor information regarding the linear force from the force sensor and for providing control information to control the rotational motion based at least in part on the sensor information.

Abstract: An example torque controlled actuator includes a frame, and one or more timing belt stages coupled in serial on the frame. The timing belt stages include an input stage for coupling to a motor and an output stage for coupling to a load, and the timing belt stages couple rotation of the motor to rotation of an output of the output stage. The torque controlled actuator also includes one or more belt idlers coupled to the frame that contact a timing belt of the output stage, and a strain gauge coupled to the frame to determine a tension of the timing belt of the output stage based on force applied by the timing belt of the output stage to the one or more belt idlers.

Abstract: Example embodiments may relate to a compliant force sensor used in actuated and non-actuated systems. For instance, a structure (e.g., a transmission) may be configured to receive a force based on application of a load to the structure. A rigid member may be coupled to the structure and configured to provide a first deformation based on application of the load to the structure and transfer of the force to the rigid member. An elastic element may provide compliance and may be connected to the rigid member such that the rigid member is configured to further transfer the force to the elastic element. The elastic member may be configured to provide a second deformation under application of the load that is larger than the first deformation. A sensor may be positioned on the rigid member and configured to measure the first deformation independent of hysteresis and non-linearity in the elastic element.

Abstract: A method for providing user content that may receive, from a user device, a request for content. The method may obtain, in response to the request, a field identifier from a multiple of field identifiers according to a priority for a multiple of fields corresponding to the field identifiers. The field identifier may correspond to a field. The method may obtain application content based on the field identifier. The method may generate declarative content from the application content. The declarative content may express the application content in a declarative programming language. The method may transmit, to the user device, the declarative content.

Abstract: Example embodiments may relate to a series elastic actuator (SEA). The SEA may include a motor, a transmission assembly, and an output plate that collectively form a motor housing assembly. The motor housing assembly may be supported on bearings that allow for a rotation of the motor housing assembly. The bearings may be supported on a housing of the SEA that may be connected to a robot link. Springs may be connected between the housing and the transmission assembly. The springs may be connected such that friction is reduced between the balls and races of the bearings. A sensor may be configured to measure a rotary deflection of the transmission assembly. A string may be wrapped around a rotary shaft of the sensor and ends of the string may be attached to the transmission assembly such that a rotation of the transmission assembly causes a rotation of the rotary shaft.

Abstract: A haptic simulation method determines a location of a needle assembly within a magneto-rheological fluid. The needle assembly within the magneto-rheological fluid is associated with a desired resistance value. A viscosity control signal representative of the desired resistance value is generated. The viscosity control signal is applied to a viscosity control device to vary a viscosity of the magneto-rheological fluid to achieve the desired resistance value.
