This work presents the design and testing of a soft robot for water utility pipeline inspection. The preliminary findings of this new approach to conventional methods of pipe inspection demonstrate that a soft inflatable robot can successfully traverse the interior space of a range of diameter pipes without the need of adjusting mechanical components. The robot utilizes inflatable soft actuators with adjustable radius which, when pressurized, can mobilize the robot inside the pipe, or anchor it in place.
The human hand comprises complex sensorimotor functions that can be impaired by neurological diseases and traumatic injuries. Effective rehabilitation can bring the impaired hand back to a functional state because of the plasticity of the central nervous system to relearn and remodel the lost synapses in the brain. Current rehabilitation therapies focus on strengthening motor skills, such as grasping, employ multiple objects of varying stiffness so that affected persons can experience a wide range of strength training.
This work focuses on the design, development and evaluation of a soft-inflatable exosuit for knee rehabilitation. Soft-inflatable actuators made of heat-sealable thermoplastic polyurethane (TPU) materials are fabricated in beam-like structures of I cross-section and mechanically characterized for their torque performance in knee-extension assistance. The soft-inflatable actuators are integrated into a light-weight, low-cost and bodyconforming interface to assist the quadricep muscle groups during walking.
