Wearable robotic systems for supporting a load

Wearable robotic systems including robotic limbs for supporting a load while a user moves through an environment and their methods of use are described. In one embodiment, a robotic system includes robotic limbs with first and second robotic limb segments that are movable between different configurations to support a load while a user is standing or crawling. In another embodiment, a robotic system includes first and second robotic limbs that are substantially located within a plane parallel to a frontal plane of a user when the robotic system is worn. In another embodiment, a wearable robotic system includes first and second robotic limbs and an associated base that is attachable to a user's torso. The first and second robotic limbs may include a plurality of actuators and associated robotic limb segments to couple the robotic legs to the base and control their movement.

Rapid Inspection of Aerospace Structures - Is It Autonomous Yet?

The trend to increase the usage of aging aircraft added a great deal of urgency to the ongoing need for low-cost, rapid, simple-to-operate, reliable and efficient NDE methods for detection and characterization of flaws in aircraft structures. In many cases, the problem of inspection is complex due to the limitation of current technology and the need to disassemble aircraft structures and testing them in lab conditions. To overcome these limitations, reliable field inspection tools are being developed for rapid NDE of large and complex-shape structures, that can operate at harsh, hostal and remote conditions with minimum human interface. In recent years, to address the need for rapid inspection in field conditions, numerous portable scanners were developed using NDE methods, including ultrasonics, shearography, thermography. This paper is written with emphasis on ultrasonic NDE scanners, their evolution and the expected direction of growth.
