What is DTMF robot?

DTMF is an acronym for Dual Tone Modulation Frequency. Robotic vehicle based on DTMF technology is explained in this article. Here, is a circuit that operates the robot without using a microcontroller. This circuit consists of simple DTMF Tone decoder IC and a motor driver IC.

What is mobile controlled robot?

The “mobile controlled robot” is controlled by a mobile phone that makes a call to another mobile phone attached to the robot. In the course of a call, if any button is pressed, a tone corresponding to the button pressed is heard at the other end of the call.

How does DTMF work?

DTMF technology works by having the handset generate tones at specific frequencies and playing them over the phone line when a button is pressed on the keypad. Equipment at the other end of the phone line listens to the specific sounds and decodes them into commands.

What are the materials in constructing a line tracing robot?

It consists of an IR LED and a Photo diode and some other components like comparator, LED etc. As mentioned earlier, we have used a pre – assembled IR Sensor. In case you do not have one, you can make your own sensor using the following circuit.

What’s DTMF on a cell phone?

Dual-tone multi-frequency (DTMF) tones are used by automated dial-in systems such as voicemail or where prompts are used to navigate.

Which sensor is used to make gesture controlled robot?

accelerometer
A gesture controlled robot using an accelerometer is one kind of robot which can be operated by the movement of hand by placing an accelerometer on it. This project is divided into two parts transmitter device and receiver device.

How to operate the robot without a microcontroller?

Here, is a circuit that operates the robot without using a microcontroller. This circuit consists of simple DTMF Tone decoder IC and a motor driver IC. When a key is pressed from our mobile, it generates a tone, which is a combination of two frequencies.

What is the robotic vehicle based on DTMF technology?

Robotic vehicle based on DTMF technology is explained in this article. Here, is a circuit that operates the robot without using a microcontroller. This circuit consists of simple DTMF Tone decoder IC and a motor driver IC. When a key is pressed from our mobile, it generates a tone, which is a combination of two frequencies.

How is a robot controlled by pressing a key?

When a key is pressed from our mobile, it generates a tone, which is a combination of two frequencies. Of the two frequencies, one is high frequency and another one is low frequency. This frequency can be decoded by the decoder IC into binary sequence. Using this binary sequence, the robot is controlled.

How do I Make my Robot move forward and backward?

Arrange the robot mechanically i.e. connect the wheels to the motors, place the circuit on the robot with a mobile fixed to it. Now press ‘5’ from your mobile, robot starts moving forward. Now press ‘0’ from your mobile, robot starts moving backward.
