7.6 Interface circuit to modified R/C car

Essentially you tape the microphone of the speech-recognition kit
to the speaker of the walkie-talkie. The microphone and speaker
assembly may be enclosed in a box by itself to reduce background
noise.

Training and controlling the mobile robot

The SRC on the mobile robotic platform should be trained using
the walkie-talkie, if that’s the way it will be operated and used. The
digital display on the board is active when the interface board is
connected, so it can be used to check word recognition accuracy.
Find out the range of the walkie-talkie system. Don’t let the mobile
robot travel outside of this range or you will end up running after
it yelling “stop, stop, stop” into the walkie-talkie. Controlling the
robot is as simple as talking to it, and it’s pretty impressive to boot.
