Robocam - Homemade Video Robot




Robocam is a heavy duty homemade robot platform supporting a video camera and transmitter.  The platform for Robocam is made from plywood and threaded rods.  Locomotion is provided by two surplus six volt motors connected to lawn mower wheels.  Power is provided by a lead acid battery. Rather than use a modern transistor or IC based H-bridge, Robocam uses four electromechanical relays (which make great clicking noises when in operation).  The camera is mounted on a hobby servo that allows the camera to pan back and forth under program control.  The camera is connected to a battery powered transmitter.  The transmitter broadcasts on TV frequencies so you can remotely monitor what the Robocam sees with a standard non-digital TV.  Robocam can be controlled via low cost micro-controllers like the Arduino, Basic Stamp, Propeller, etc. (not shown).  A power switch is mounted on the front of the lower platform to prevent the circuits and motors from draining the batteries when not in use.

    Instructables is for people to post "instructions" for projects- the pics are great but you really missed the point if you don't tell us how to do it.

    Actually instructables is about "sharing what you make". There are three kinds of instructables: photo instructables which allow you to upload photos of what you made, video instructables which allow you to share videos of your projects, and step by step instructables which adds instructions to photos in a step by step format. (see This instructable is a photo instructable.
