Development of wheelchair that can acsend and descend unknown height step by using disturbance observer by Fumiaki TAKEMORI

“…In addition, it was confirmed that wheelchair with an adult man actually boarded can ascend and descend step height of 140 mm, as a result of implementing an arm movement model that realizes step up and down while maintaining the posture of the wheelchair body horizontally for the arm mechanism after touchdown.…”

Visual augmentation of deck-landing-ability improves helicopter ship landing decisions by Mathieu Thomas, Julien R. Serres, Thomas Rakotomamonjy, Franck Ruffier, Antoine H. P. Morice

“…Abstract When attempting to land on a ship deck tossed by the sea, helicopter pilots must make sure that the helicopter can develop sufficient lift to be able to safely touchdown. This reminder of affordance theory led us to model and study the affordance of deck-landing-ability, which defines whether it is possible to land safely on a ship deck depending on the helicopter's available lift and the ship’s deck heave movements. …”
