Smartphone CanSat for Actualization of Real-time Streaming Video Calls Using Remote Screen Touch System with Shape Memory Alloy Actuator

Abstract

This paper reports the Smart Call from the Sky (SCSky) Can Satellite (CanSat) platform developed by Chosun University, South Korea, with a focus on a smart material of shape memory alloy actuator applications. The primary objective of this study is to verify the effectiveness of a remote screen touch system using shape memory alloy wires. The system is currently being utilized to operate the on-board smartphone of a CanSat by telecommands from a ground station. It provides real-time streaming video showing the internal and external states of CanSat through video calls during actual flight. The secondary objective of the mission is to acquire a wide-scan image from the on-board USB cameras, whose elevation angles are actuated using shape memory alloy springs. The effectiveness of the design proposed was validated experimentally through actual flight tests using model rockets.

Towards Electron-Beam-Driven Soft / Polymer Fiber Microrobotics For Vacuum Conditions

“…As practice shows, this indirect and not always accessible way of solving problems (the transition from macroscale to microscale robotics and the introduction of non-standard interpretations despite the inconsistency with the high-budget mainstream) can help in obtaining non-standard results using spacecraft, as was the case decades ago [44][45][46]. A fibrillar manipulator cannot replace a macromanipulator, but for nanosatellites and picosatellites (such as "CanSat"), sets of cooperative fibrillar manipulators with the electron beam control may be the only possible means of achieving efficiency in many mechanical applications including pulsed one-time manipulations (such as opening a mirror or a solar battery) [47][48][49][50][51][52][53][54][55][56][57].…”

Fabrication of Smart Materials Using Laser Processing: Analysis and Prospects

“…Smart materials with shape memory properties are used in robotics to create self-deploying structures and adaptive robotic components [15]. Shape memory alloys can be integrated into consumer electronics, such as smartphones, to enable adaptable form factors or user interfaces [163]. Shape change materials can be employed in automotive applications, such as self-healing or adaptive panels [164,165].…”
