Design and Development of Android-Based BOT for Medicine and Food Distribution to Patients

The Android-based robot can be used for applications such as spy bots, it can also be used for supplying medicines to the patients. This Android-based robot which is driven by the “to and fro” movement of Android phone can also distribute medicines to the suffering patients. The robot is connected to the Android phone through Bluetooth module. In this research, a wireless robot is designed by using serial communication and Bluetooth process for wireless transmission of data and an Android mobile. A Bluetooth module has been interfaced with CPLD device and connected with Android operating system-based mobile. By using this mobile APP transmission of data to CPLD is done and it will receive data by using Bluetooth module and according to the requirement the robot will work. This application in mobile will transmit ASCII of the characters—“W,” “A,” “S,” and “D” to the robot. The robot will receive these characters using Bluetooth module and it will perform the operations—“Forward,” “Backward,” “Left,” and “Right.”
