GSM Cell Phone Operating Robot Seminar Report: Radio control abbreviated as R/C or RC uses radio signals to control a device remotely. It is used to refer to control the model vehicles with the help of hand-held radio transmitter. It is used in many fields like Industries, military and scientific research organizations. A remote control vehicle is a mobile device which is controlled by a means but does not restrict motion to the device.
A radio control device is like a cable between control and vehicle or an infrared controller. A remote control vehicle is different from a robot where RCV is controlled by a human. It is important that a vehicle must proceed accurately to a reach an area, to fulfill its mission and returning accurately and safely.
Sony Ericsson has released a remote control car recently which is controlled by Bluetooth cell phone. Radio is the most popular since it does not need the vehicle to limit its length. Bluetooth is expensive and has short range to viable commercially.
The First Remote Control Vehicle/Precision Guided Weapon built by Nikola Tesla in 1898. Every remotely operated vehicle present in air, land or sea is powered by lead-acid batteries and an electric drive motor.
The technology used in this project, Dual-Tone Multi-Frequency (DTMF) signaling is used between telephone handsets and other communications devices and the switching center for telecommunication signaling over analog telephone lines in the voice-frequency band. The version of DTMF is known by term Touch-Tone and is standardized by ITU-T Recommendation Q.23.
Cable television broadcasters used DTMF tones as a method of in-band signaling for indication of start and stop times of local commercial points for the benefit of cable companies.
GSM Cell Phone Operating Robot Seminar Report Conclusion:
Hence small scale remote control vehicles are popular among hobbyists. These remote controlled vehicles have a wide range in price and sophistication. There are many kinds of radio controlled vehicles which include on-road cars, off-road trucks, boats, airplanes, and even helicopters.
