Rumble Robots

Rumble robots have been the most popular robots to hit the market in the year of 2001. There was no extraordinary mechanics used in the production of this machine but still it was very innovative in its working. The main feature of this robot was its gaming facility. The only change in the working of rumble robots was the kind of transmitter that it was employing in its system and that made it unique.

Almost all RC toys are controlled by the radio transmitter. When you press for a certain control then the transmitter transmits a prefixed radio signal of a unique frequency to the receiver placed inside the toy. The receiver receives the signal, processes it and then actuates the mode set for that signal. Thus in this way you will be able to see a particular move when it is pressed. The same process is used in the rumble robots; it just uses infrared instead of the radio waves to send the signals. It consists of a diode which transmits the infrared at a particular frequency which is then received by the receiver in the rumble robots. The receiver, or the sensor, then deciphers the signal and works accordingly.

The technology which is used in the rumble robots is same as that used in a T.V. The remote control of the rumble robots consists of the following parts:

- LED
- 3 batteries
- 2 circuit boards

Like any other robot of the present times, the rumble robots use the printed circuitry. It is usually made up of a thin fiberglass piece and different kinds of copper wires are etched on the surface of the fiberglass.

The circuitry of the rumble robots includes components like transistors, capacitors and diodes. It also includes integrated circuit and it also includes a number of buttons. These buttons are a key element for the toy and whenever you press the key of the remote control then it pushes a particular button inside it. This buttons then completes a particular circuit providing it a conducting path and in the process IR is emitted. It is then received by the sensors in the toy and it works accordingly, hence this is the process by which the rumble robots work.
