South Korean engineers have created a case for the smartphone, equipped with feet, by which he can creep in the right direction. As an example, the developers demonstrated how a smartphone independently moved to wireless charging. An article about the case published in IEEE Robotics and Automation Letters, she drew the attention of the publication IEEE Spectrum.
In the middle of the 2010s years, several smartphone manufacturers have been mining in the field of modular smartphones, which could be expanded with additional components. The most notable such project is Google’s Ara, and not embodied in serial form. It’s also worth noting LG G5, in which the battery can be replaced by the module with the battery and buttons on the camera or on a module with improved digital-to-analog Converter.
Greater success has reached a different concept in which functions can be expanded through optional overlays or covers. For example, Motorola a few years sold smartphonesthat support overhead modules on the back surface, without which they were still able to function normally, and Apple still sells for their smartphone cases with extra battery and a manual control button camera.
Engineers from South Korea under the leadership of Cho Gyu-Jin (Kyu-Jin Cho) from Seoul national University have created a prototype robocable, allowing the smartphone to move independently. Case width almost equal to that of the smartphone, and the length is considerably greater it: over the top frame of the smartphone is a part of the cover that hides the motors and other components. The weight of the case is 81,55 grams without regard to smartphone.
The case is equipped with two motors and six legs. Feet on each side synchronously driven by one motor via a crank mechanism. During movement, the robot raises and lowers legs, as they bend only in one direction, each step moving forward. And to turn it changes the speed of motors on one side. In the present case operates under the control of the operator, but the authors propose to equip it with an Autonomous control system.
