The Clare™ 8088 – a commercially available DTMF transceiver chip – is used to generate the signal.The signal is then amplified for audible output via a small 8-ohm speaker.On the receiving side,a condenser microphone is used to pick up the signal.The signal is then deciphered and acknowledge by the receiver robot.The receiver robot then takes the appropriate action as commanded by the sender to prove successful transmission.Figure 3A shows the DTMF hardware on the Handyboard controller,Figure 3B shows the robot setup with DTMF capability.
Remark:There is an issue arose during implementation of the hardware that requires attention.Most of small-scale mobile robots use battery packs that have limited power output capability.This limitation of the robot’s onboard power supply sets a limit on the maximum power delivered to the speaker and consequently its effective range.For the implementation of this experiment,the author is satisfied that the current amplification is s
