Abstract: Exemplary embodiments relate to various improvements in soft robotic actuators, and techniques for manufacturing the improvements. For example, techniques for manufacturing a rigidizing layer for reinforcing a soft robotic actuator is provided. In another embodiment, a soft robotic actuator having integrated sensors is described. A flexible electroadhesive pad for achieving a conformal grip is also described. Still further, exemplary embodiments provide hydraulically-actuated soft robotic grippers, which allows for a reduction in the size of the actuation system and improved underwater operation.

Abstract: A power-assist lower limb exoskeleton robot with adjustable stiffness joints includes a human-robot information interaction unit, an electronic control unit, an electro-hydraulic servo driving unit and a mechanical structure unit of a lower limb exoskeleton. In the mechanical structure unit of the lower limb exoskeleton, a hip joint and a hip joint connector are connected by a cross hinge mechanism. In combination with a bidirectional hydraulic cylinder, the hip joint of the lower limb exoskeleton fits well with the space structure characteristics of a human hip joint. The unidirectional hydraulic cylinders with spring reduction meets the needs of fast response and large torque during walking and increases walking endurance time. The present invention uses a plantar pressure information collection unit and a waist gyroscope to collect the human gait and gesture information. Besides, it uses a crutch unit to introduce wearer's movement intention into the exoskeleton robot's cooperative control.

Abstract: A material-mapped actuator useful as, or as part of, a soft robot along with automated methods of design and manufacture. The actuator exhibits mechanical properties that spatially vary along a coordinate system of the actuator. The actuator body has an initial shape with a corresponding initial map of mechanical attributes consisting of locally-varying stiffness at each point in a volume of the actuator body. The actuator is configured to change to a different shape or distribution of mechanical properties upon being activated by an actuation medium. The map of mechanical attributes influences and determines the new shape or distribution. The material-mapped actuator can incorporate a spatially-varying distribution of mechanical properties that dictates multiple desired shapes as the actuation medium is applied, including an actuation sequence in which the actuator transitions from a first shape to a desired intermediate shape(s), and from the intermediate shape to a desired final shape.
