Sentinel

Sentinel is a tool for better bringing-together.

From conference calls on speakerphone to wheeled telepresence robots, the technology behind remote conversations has always been evolving - but perhaps not fast enough. No matter which medium it's expressed in, a wireless conversation is constrained by the inability to perceive emotion or understand body language.

That barrier to effective human communication is resolved with Sentinel.

Details

Two NEMA-17 stepper motors provide 80 N*m torque to a powerful pan-tilt device, on which a smartphone can be placed. An Arduino microcontroller drives the motors. Phone gyroscope readings pan and tilt the device correspondingly, to provide a realistic conversational experience.
