| dc.description.abstract | This thesis aims to improve the mobility of the wheeled-type robot. Combining with jumping function, the wheeled-model robot can work effectively in two usual conditions in a house: for the wheeled-model, it can move fast on the smooth surface; for the jumping-model, it can jump over low obstacles. In jumping-model, we use DC motor to compress two springs in the jumping mechanism. The Y-shaped absorbers are set in its wheels for avoiding the damage when the robot is jumping or accidentally falling down the stairs,. The body of the robot is made up with carbon and ABS plastic to reduce its weight. Besides, to enhance the mobility of the robot moving in wheeled-type, the designed fuzzy controller can adjust its moving way to match the specified trajectory. The robot can be used in homecare system based on embedded Raspbian operation system. Through a computer or a smartphone, the robot can capture and transmit its front environment image to the user in real-time. In addition, due to the installed sensor, the system has an SOS switch for an emergency situation and an SMS messages for warning users.
In this thesis, we successfully design and fabricate a wheeled-type robot with jumping function. The ability of jumping function can make the robot jumping with 25 cm vertically and 25 cm horizontally in maximum such that the robot cross the obstacles stably on the uneven surface, e.g., sill of doors and stairs. Furthermore, the robot can execute the monitor task in homecare application effectively. | en_US |
