SHOWALL HIGH VOLTAGE ROBOTICS

The 4x4 truck base contained all of the drive electronics, transmission parts, and battery pack all in the base, which made it easy to simply build on top of the platform. I planned to keep the drive motors running from the original 12 volt battery pack and add a separate pack for the lights, video transmitter and additional subsystems so that run times would be extended. The only puzzle here was how to control the functions such as the payload delivery system and camera pan head by utilizing the original remote control. No doubt, a good hack will present itself, so I started by creating the new all weather body to add over the RC truck base.

I wanted the new body to be fully weather proof, robust and much heavier than the original plastic truck cover. Since the drive system has more power than it would probably ever need, it made sense to actually weigh down the unit for better traction which would allow it to slowly sneak through tall grass, up hills and run in soft dirt. A had a lot of scrap 1/16 inch thick sheet metal lying round my shop after making my other robot "Goober", so I decided to use the left over pieces to make the body for this spy robot as well.

The body will be a simple turtle shell with a rounded top and flat sides, as this would lend itself well to running though areas with tall grass or bush, making the robot slip though without getting snagged. The two side panels were cut with wheel wells and a rounded top and the center strips are cut out to be as wide as the truck bas so the new body will fit snuggly over the plastic base.
