Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

A remote control system to operate a manipulator arm by the HAL (Hybrid Assistive Limb) robot suit is examined in the application of in-cell equipment maintenance. In this integrated system the operator wears the exoskeletal-structured HAL and the operator's movement is transferred through HAL's computer system to a slave-type manipulator arm. The system includes a bioelectrical signals (BES) control scheme and a position control scheme. In the former scheme, sensors attached to the skin on the operator's arms detect faint BES when the operator makes a movement. The signals are processed and analyzed by a computer to determine the operator's intention. The computer then calculates the necessary assistive power and the power units generate adequate power to each joint of the HAL suit to assist the operator. To evaluate the effectiveness and usefulness of the system, remote handling experiments were designed using mockup equipment, and the performance of remote operation conducted by the two schemes mentioned above was compared with that by the more conventional three-dimensional mouse control scheme. Of these three control schemes, the BES control scheme clearly outperformed the others in executing direct-contact tasks of in-cell equipment maintenance with small operation time and small variation.
