A self-recovery mechanism for quadrotors
2014 IEEE International Conference on Robotics and Biomimetics (ROBIO 2014), 2014Flying robots have many applications in constrained environments. But they are facing difficulties when they cannot take off again without human intervention if they are not in upright position after a fall. This paper presents a method to design a self-recovery mechanism for the quadrotor to protect itself and recover autonomously after accidental ...

Self-Recovery Superhydrophobic Surfaces
2021Superhydrophobic surfaces are already being used in processes such as self-cleaning, water-oil separation, water harvesting, and other fields. Surfaces are defined as superhydrophobic when they consist of densely packed protrusions on the nanoscale and/or microscale, with side walls that have tilt angles exceeding the advancing contact angle of water ...

Two theories have been put forward to account for the broadening of the X-ray reflexions given by cold-worked metals. First, the crystals may be broken down into small mosaic elements (fragmentation)1, or, secondly, they may be so distorted by the stresses (microstresses) present that the lattice parameter varies over a range of values2.
