mobile robot schematics
The mobile robot schematic diagram is designed for operation via a cellphone interface, utilizing several key components to facilitate control and movement. The DTMF (Dual-Tone Multi-Frequency) decoder, specifically the MT8870 or CM8870, serves as the primary interface for receiving commands from the cellphone. This decoder interprets the DTMF signals generated by the cellphone keypad, converting them into corresponding digital signals that can be processed by the microcontroller.
The microcontroller at the heart of this system is the ATMEGA16, which is responsible for interpreting the output from the DTMF decoder and executing the appropriate control logic. It processes the signals received and determines the actions that the robot should perform, such as moving forward, backward, or turning.
To drive the robot's movement, a motor driver, specifically the L293D, is employed. This component acts as an interface between the microcontroller and the DC motors, allowing the low-power signals from the microcontroller to control the higher-power motors effectively. The L293D can drive two DC motors simultaneously, providing the capability to control the direction and speed of the robot's movement.
The actuators used in this mobile robot are DC motors rated for 5-6V. These motors convert electrical energy into mechanical energy, enabling the robot to move. The selection of these motors is crucial as they must provide adequate torque and speed for the intended application, ensuring the robot can navigate effectively.
Overall, this schematic diagram integrates these components to create a functional mobile robot that can be controlled remotely via a cellphone, showcasing the synergy between telecommunications and robotics.Mobile robot schematic diagram for cellphone controlled robot.
