Reynolds Fits LPRS Easy-Radio In Interviewer Robot
The biggest design issue was the audio interaction between the robot and the interviewee. A method was required to remotely play back more than 200 words and phrases accurately and quickly to make the interviews run smoothly. Nothing existed off the shelf, so Reynolds undertook a custom design employing an MP3 playback unit, amplifier and speaker located in the chariot that would produce the humanoid's voice.
An RS232 input stream operates the unit, and a modified USB keyboard outputs the required instruction data stream to remotely provide the words and phrases. Reynolds decided to use an LPRS Easy-Radio to transmit the data over RF to the receiver in the chariot.
A spokesperson from Reynolds said: 'The LPRS Easy-Radio modules were a breath of fresh air and could be put directly into the data stream, with no extra circuitry or software tweaks required. 'The modules worked flawlessly out of the box and as an added bonus were slim enough to fit directly into the back of the keyboard unit. 'The robot could now speak to any guest directly and any phrase or saying could be accessed at the touch of a button. 'The modules worked quickly enough to allow multiple phrases and names to be strung together.
