Robot brains

 TalkBotBrain v1
TalkBot Brain - IS NOW ON SALE!

This miniature robot controller "brain" features a PIC microcontroller and 1 Megabit of eeprom sound storage. It can control 8 servos and play up to 256 sounds, so this tiny PCB (45 x 34mm) can act as a complete talking robot brain.

TalkBot Brain comes fully assembled with surface mount ICs, and is already programmed with "slave" software. The slave software accepts 2-byte serial commands using just one PIC pin to control 8 servos and play sounds. You just need to attach a DC power source (5v to 15v) and a speaker.

 TalkBotBrain and Servo

TalkBot Brain has open-source PIC software, all the PIC source code is provided in C. You can use it straight out of the box to add speech and extra servos to your existing robot, or reprogram the PIC yourself so that TalkBot Brain becomes a stand-alone controller for a small simple robot or other device.

Make your robot talk!

We provide free easy to use Windows software that enables you to take sounds from any wave (.WAV) files, join the sounds into one handy sound "library" and download the sound library direct into TalkBot Brain. Add speech to a robot or home appliance, build a talking clock, the applications are up to you. You do not need to do any PIC programming to load your own sounds into TalkBot Brain.

TalkBot Brain holds a total of 23.8 seconds of 1.5bit sound, indexed for playback of up to 256 individual sounds, all at a playback rate of 44.1kHz. That is about 50 spoken words!
