Surveillance Module for Father AI
The Father AI requires a surveillance module. To that end, the above device was constructed to proof out the basic components and functions.
The central component of the system is the sensors head. This unit consists of a video camera and an ultrasonic sensor. The items are arranged to imitate a face. The housing is made of acrylic and custom cut at LVL1 on it's laser cutter.
The sensors head is placed upon a simple pan and title mechanism driven by servo motors.
The pan and tilt mechanism is mounted onto a project board which also holds the electronics.
Finishing out the device is a NTSC monitor.
The basic operation of the module is to allow the user to control a camera's motions, recieve video and have a sensor reading on distance between the camera and the observed. For this build, the module displays distance on the monitor when it is below 50 centimeters. Motion is controller by a user joystick. The servos are driven by a serial servo controller. The distance is recorded by an ultrasonic sensor with the result overlayed over the video by a Video Experimenter board.
