“Mobile Autonomous Robotic Virtual Intelligence Node”Or
“Make A Robot Virtually Intelligent Now”
Main Features Smart Navigation Various visual and audio interactions Connectivity Remote Control
Raspberry Pi “brain” Barebone ATmega as central nervous system Servo driver for motor functions Sensors, camera and external devices for
perception
Intend to reproduce life behaviour• Environnement analysis and interaction
• Inlude some Chaotics reactions to create new behaviours
Anatomy
Screen breakout board • 3,3v and 5v I²C
• 3,3v UART
