Internet of Things Technology Applies to Two Wheeled Guard Robot with Visual Ability

In this study, a two wheeled guard robot (TWGR) system with visual ability is realized. The hardware of the TWGR includes a chassis carrying dc motors for wheels, the input/output (I/O) board connects the TWGR system to a personal computer (PC) and Personal Digital Assistant (PDA), driver circuits for the motors, the necessary sensors and filter circuit needed to measure system states. Moreover, camera system and image transmission module are also connected to the chassis. Moreover, based on Internet of Things (IoT) technology, all system state and real-time image from the visual system can be transmitted to the cloud server through the Internet. Administrator is able to access the cloud server to monitor each TWGR immediately. Finally, TWGRs can be controlled remotely to deal with any emergency situation.
