Two way intercom design for tele-operated robot Answered
I'm working on building a tele-operated robot that will be able to send signals generated by moving your arms and mapping these to the robot arms. I'm looking to add an intercom system to the robot that would allow for the operator to speak into a microphone and come out a speaker on the robot and a microphone on the robot so send audio that someone speaking to the robot generates to the operator.
I've currently been looking into VOX circuits and walkie talkies but all walkie talkies I have seen require both sides to use a headset. It would be fine for the operator of the robot to use a headset but it would be better for the speaker and microphone on the robot to be out loud.
Does anyone have ideas about how this type of system could be implemented? Could I replace the PTT button on a walkie talkie with a voice activated switch kit available online?
