Sound-seeking robot called PeanutBot consists of three microphone circuits, three servo motors, an MCU and a PC. It can triangulate the angle of source and detects the arrival time of the signal at certain amplitude approaching at each of its microphone. The autonomous robot records the microphone data at 10 microsecond intervals for 10 milliseconds and do not synchronized with the pulse generator. Three programmers Angela Israni, Hemanshu Chawda and Seth Spiel from Cornell University made this Autonomous Sound Finding Robot as their project for the ECE 476 Designing with Microcontrollers course. It doesn’t require any sort of guidance and can follow the source itself. It took them only $361 to put it into shape and out of this amount, $325 was spent only on BrainStem PPRK autonomous robot kit.
