TL;DR: The state of the art in the design of actuators with adaptable passive compliance is described, which is not preferred for classical position-controlled applications such as pick and place operations but is preferred in novel robots where safe human- robot interaction is required or in applications where energy efficiency must be increased by adapting the actuator's resonance frequency.

TL;DR: The structural design, control system, and integrated biofeedback for a wearable exoskeletal robot for upper extremity stroke rehabilitation are presented and the device has four actuated degrees-of-freedom driven by compliant and safe pneumatic muscles on the shoulder, elbow, and wrist.

TL;DR: In this article, a unique, robust, robotic transtibial prosthesis with regenerative kinetics was successfully built and a 6-month human subject trial was conducted on one male below-the-knee amputee under linear walking conditions.

TL;DR: Results from many experiments are described that demonstrate the ability of the system to carry flexible boards and large boxes as well as the system's robustness to alignment and odometry errors.

TL;DR: Using this approach, an initial prototype has provided 100% of the power and energy necessary for ankle gait in a compact 0.95 kg package, seven times less than an equivalent motor/gearbox system.
